TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
|

-----------------------------------------------------------
|
||||
|
||||
PREAMBLE
|
||||
The goals of the Open Font License (OFL) are to stimulate worldwide
|
||||
development of collaborative font projects, to support the font creation
|
||||
efforts of academic and linguistic communities, and to provide a free and
|
||||
open framework in which fonts may be shared and improved in partnership
|
||||
with others.
|
||||
|
||||
The OFL allows the licensed fonts to be used, studied, modified and
|
||||
redistributed freely as long as they are not sold by themselves. The
|
||||
fonts, including any derivative works, can be bundled, embedded,
|
||||
redistributed and/or sold with any software provided that any reserved
|
||||
names are not used by derivative works. The fonts and derivatives,
|
||||
however, cannot be released under any other type of license. The
|
||||
requirement for fonts to remain under this license does not apply
|
||||
to any document created using the fonts or their derivatives.
|
||||
|
||||

<p>TLSNotary is a protocol which allows users to export data from any website in a
|
||||
credible way. This way they can verify the authenticity of parts of a
|
||||
TLS-encrypted web session without compromising on privacy.</p>
|
||||
<p>It works by adding a third party, the Notary, to the usual TLS connection
|
||||
between the User and a web server. The User forwards the encrypted TLS traffic
|
||||
to the Notary which checks that it has not been tampered with and notarizes the
|
||||
whole TLS session by signing a transcript of it.</p>
|
||||
<p>The User can now use this transcript and disclose parts of it to another
|
||||
party, which we call the Verifier. The Verifier only needs to trust the Notary
|
||||
in order to accept proofs from many different users. This way, TLSNotary
|
||||
can be used for a variety of purposes. For example you can use TLSNotary to
|
||||
prove that</p>
|
||||
<ul>
|
||||
<li>you have received a money transfer using your online banking account, without
|
||||
revealing your login credentials or sensitive financial information.</li>
|
||||
<li>you have access to an account on a web platform.</li>
|
||||
<li>a website showed some specific content on a certain date.</li>
|
||||
</ul>
|
||||
<p>Overall, the TLSNotary protocol can be used in any scenario where you need to
|
||||
prove to a third party facts about the content of a TLS connection.</p>
|
||||
<p>Some interesting aspects of TLSNotary are:</p>
|
||||
<ul>
|
||||
<li>The protocol is transparent to the web server, because it is not aware of the
|
||||
notarization process. For the server it just looks like normal browsing.</li>
|
||||
<li>Data is kept private from the Notary. The Notary only sees the ciphertext and
|
||||
never has access to the plaintext.</li>
|
||||
<li>No modifications to the TLS protocol are needed. You can use it without any
|
||||
changes to web servers.</li>
|
||||
<li>The Notary and the Verifier can be the same entity. That means if you as a
|
||||
Verifier do not want to trust some Notary server, you can run one yourself.</li>

|

<p>Some protocols used in TLSNotary need to convert two-party sharings of products
|
||||
or sums of some field elements into each other. For this purpose we use share
|
||||
conversion protocols which use oblivious transfer (OT) as a sub-protocol. Here
|
||||
we want to have a closer look at the security guarantees these protocols offer.</p>
|

<h3 id="adding-covert-security"><a class="header" href="#adding-covert-security">Adding covert security</a></h3>
|
||||
<p>Our goal is to add covert security to our share conversion protocols. This
|
||||
means that we want an honest party to be able to detect a malicious adversary,
|
||||
who is then able to abort the protocol. Our main concern is that the adversary
|
||||
might be able to leak private inputs of the honest party without being noticed.
|
||||
For this reason we require that the adversary cannot do anything which would
|
||||
give him a better chance than guessing the private input at random, which is<br />
|
||||
guessing <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6944em;"></span><span class="mord mathnormal" style="margin-right:0.03148em;">k</span></span></span></span> bits with a probability of <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.8491em;"></span><span class="mord"><span class="mord">2</span><span class="msupsub"><span class="vlist-t"><span class="vlist-r"><span class="vlist" style="height:0.8491em;"><span style="top:-3.063em;margin-right:0.05em;"><span class="pstrut" style="height:2.7em;"></span><span class="sizing reset-size6 size3 mtight"><span class="mord mtight"><span class="mord mtight">−</span><span class="mord mathnormal mtight" style="margin-right:0.03148em;">k</span></span></span></span></span></span></span></span></span></span></span></span> for not being detected.</p>

deviate from the protocol.</p>

<h4 id="malicious-receiver"><a class="header" href="#malicious-receiver">Malicious receiver</a></h4>
|

<p>Note that in our protocol a malicious receiver cannot forge the protocol output,

since he does not send anything to the sender during protocol execution. Even

when this protocol is embedded into an outer protocol, where at some point the

receiver has to open his output or a computation involving it, then all he can

do is to open an output <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.9463em;vertical-align:-0.1944em;"></span><span class="mord"><span class="mord mathnormal" style="margin-right:0.03588em;">y</span><span class="msupsub"><span class="vlist-t"><span class="vlist-r"><span class="vlist" style="height:0.7519em;"><span style="top:-3.063em;margin-right:0.05em;"><span class="pstrut" style="height:2.7em;"></span><span class="sizing reset-size6 size3 mtight"><span class="mord mtight"><span class="mord mtight">′</span></span></span></span></span></span></span></span></span></span></span></span> with <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.9463em;vertical-align:-0.1944em;"></span><span class="mord"><span class="mord mathnormal" style="margin-right:0.03588em;">y</span><span class="msupsub"><span class="vlist-t"><span class="vlist-r"><span class="vlist" style="height:0.7519em;"><span style="top:-3.063em;margin-right:0.05em;"><span class="pstrut" style="height:2.7em;"></span><span class="sizing reset-size6 size3 mtight"><span class="mord mtight"><span class="mord mtight">′</span></span></span></span></span></span></span></span></span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel"><span class="mrel"><span class="mord vbox"><span class="thinbox"><span class="rlap"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="inner"><span class="mord"><span class="mrel"></span></span></span><span class="fix"></span></span></span></span></span><span class="mrel">=</span></span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.625em;vertical-align:-0.1944em;"></span><span class="mord mathnormal" style="margin-right:0.03588em;">y</span></span></span></span>, which is just equivalent to

<h3 id="replay-protocol"><a class="header" href="#replay-protocol">Replay protocol</a></h3>
|
||||
<p>In order to mitigate the mentioned protocol deviations in the case of a malicious
|
||||
sender we will introduce a replay protocol.</p>
|
||||
<p>In this section we will use capital letters for values sent in the replay
|
||||
protocol, which in the case of an honest sender are equal to their lowercase
|
||||
counterparts.</p>
|
||||
<p>The idea for the replay protocol is that at some point after the conversion
|
||||
protocol, the sender has to reveal the rng seed <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span></span></span></span> and his input <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal">a</span></span></span></span> to the
|
||||
receiver. In order to do this, he will send <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal" style="margin-right:0.00773em;">R</span></span></span></span> and <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal">A</span></span></span></span> to the receiver after
|
||||
the conversion protocol has been executed. If the sender is honest then of
|
||||
course <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">==</span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal" style="margin-right:0.00773em;">R</span></span></span></span> and <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal">a</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">==</span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal">A</span></span></span></span>. The receiver can then check if the value he picked

during protocol execution does match what he can now reconstruct from <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal" style="margin-right:0.00773em;">R</span></span></span></span> and

|

<p><strong>Using this replay protocol the sender at some point reveals all his secrets
|
||||
because he sends his rng seed and protocol input to the receiver. This means
|
||||
that we can only use covertly secure share conversion with replay as a
|
||||
sub-protocol if it is acceptable for the outer protocol, that the input to
|
||||
share-conversion becomes public at some later point.</strong></p>
|
||||
<p>Now in practice we often want to execute several rounds of share-conversion, as we
|
||||
need to convert several field elements. Because of this we let the sender use
|
||||
the same rng seed <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span></span></span></span> to seed his rng once and then he uses this rng instance
|

|

<p>Having a look at the ways a malicious sender could cheat from earlier, we
|
||||
notice:</p>
|
||||
<ol>
|
||||
<li>The sender can no longer impose an arbitrary field element <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.7519em;"></span><span class="mord"><span class="mord mathnormal">b</span><span class="msupsub"><span class="vlist-t"><span class="vlist-r"><span class="vlist" style="height:0.7519em;"><span style="top:-3.063em;margin-right:0.05em;"><span class="pstrut" style="height:2.7em;"></span><span class="sizing reset-size6 size3 mtight"><span class="mord mtight"><span class="mord mtight">′</span></span></span></span></span></span></span></span></span></span></span></span> onto the
|
||||
receiver, because the receiver would notice that <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="mord mathnormal">t</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel"><span class="mrel"><span class="mord vbox"><span class="thinbox"><span class="rlap"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="inner"><span class="mord"><span class="mrel"></span></span></span><span class="fix"></span></span></span></span></span><span class="mrel">=</span></span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal" style="margin-right:0.13889em;">T</span></span></span></span> during the replay.</li>
|
||||
<li>The sender can still carry out a selective-failure attack, but this is
|
||||
equivalent to guessing <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6944em;"></span><span class="mord mathnormal" style="margin-right:0.03148em;">k</span></span></span></span> bits of <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6944em;"></span><span class="mord mathnormal">b</span></span></span></span> at random with a probability of
|

|
||||
<li>The sender is now forced to use an rng seed to produce the masks, because
|
||||
during the replay, these masks are reproduced from <span class="katex"><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6833em;"></span><span class="mord mathnormal" style="margin-right:0.00773em;">R</span></span></span></span> and indirectly checked

|

<p>At the end of the TLSNotary protocol, the User has the authenticated AES ciphertext which can be thought of as a commitment to the plaintext. This form of commitment is not amenable to use cases when the User wants to make part of the plaintext public while keeping another part private. Naively, the User's option is to prove the decryption of the ciphertext in zero-knowledge which is computationally expensive.</p>
|
||||
<p>We describe two less computationally heavy approaches for converting the AES ciphertext commitments. </p>
|
||||
<p>The first approach is useful for commitments to the data which the User intends to make public. It is based on decrypting the ciphertext with Garbled Circuits and producing a hash commitment to the wire labels.</p>
|
||||
<p>The second approach is useful for commitments to the private data which the User later intends to prove statements about in zero-knowledge. This approach produces a Poseidon hash over the private data. </p>

<h1 id="notarization-phase"><a class="header" href="#notarization-phase">Notarization Phase</a></h1>
|
||||
<p>During the Notarization Phase the <code>Requester</code>, otherwise referred to as the <code>User</code>, and the <code>Notary</code> work together to generate an authenticated <code>Transcript</code> of a TLS session with a <code>Server</code>.</p>
|
||||
<p>Listed below are some key points regarding this process:</p>
|
||||
<ul>
|
||||
<li>The identity of the <code>Server</code> is not revealed to the <code>Notary</code>, but the <code>Requester</code> is capable of proving the <code>Server</code> identity to a <code>Verifier</code> later.</li>
|
||||
<li>The <code>Notary</code> only ever sees the <em>encrypted</em> application data of the TLS session.</li>
|
||||
<li>The protocol guarantees that the <code>Requester</code> is not solely capable of constructing requests, nor can they forge responses from the <code>Server</code>.</li>
|
||||
</ul>
|
||||
<h2 id="requester"><a class="header" href="#requester">Requester</a></h2>
|
||||
<p>The <code>Requester</code> is the party which runs the TLS connection with the <code>Server</code>. The <code>Requester</code> constructs application payloads, eg. HTTP requests, and coordinates with the <code>Notary</code> to encrypt them with the TLS session keys prior to sending them. Subsequently, the <code>Requester</code> works with the <code>Notary</code> to decrypt responses from the <code>Server</code>. The plaintext of the application data is only ever revealed to the <code>Requester</code>.</p>
|
||||
<h2 id="notary"><a class="header" href="#notary">Notary</a></h2>
|
||||
<p>The <code>Notary</code> is the party of which the authenticity of the <code>Transcript</code> relies on. During the session the <code>Notary</code> withholds its' shares of the TLS keys and participates in a series of secure 2-party computation protocols with the <code>Requester</code> to operate the TLS connection.</p>
|
||||
<h2 id="server"><a class="header" href="#server">Server</a></h2>
|
||||
<p>The <code>Server</code> can be any server which supports TLS. The TLSNotary protocol is entirely transparent to the <code>Server</code>, thus it can not be censored nor does it have to support any additional functionality.</p>
|
||||
<img src="https://raw.githubusercontent.com/tlsnotary/docs-assets/main/diagrams/tls12-multiround.png">
|
||||
<h2 id="transcript"><a class="header" href="#transcript">Transcript</a></h2>
|
||||
<p>The primary artifact generated from this phase is called the <code>Transcript</code>. It contains session meta-data, handshake data, and commitments to all the requests and responses. Typically the <code>Transcript</code> is signed by the <code>Notary</code>, however that is not necessary in the case where the <code>Notary</code> will also act as the <code>Verifier</code> in the selective disclosure phase.</p>
|
||||
<blockquote>
|
||||
<p>Note that the server ephemeral key does not reveal the identity of the server to the <code>Notary</code>.</p>

<p>The pre-master secret (<code>PMS</code>) must be put through a <code>PRF</code> (pseudo-random function) defined by the TLS spec in order to compute the symmetric TLS keys and also to compute the <code>verify_data</code> for the <code>Client_Finished</code> and the <code>Server_Finished</code> messages.</p>
|
||||
<p>Below we describe how the parties (<code>N</code> stands for <code>Notary</code> and <code>U</code> stands for <code>User</code>) who have their shares of <code>PMS</code> can use 2PC to compute the <code>PRF</code>. </p>
|
||||
<blockquote>
|
||||
<p>Since the TLSNotary protocol already uses Garbled Circuits and Oblivious Transfer which give 128-bit computational security for the parties against each other, we argue that it is acceptable to perform some PRF computations outside of 2PC as long as it is done with at least 128-bit security.
|
||||
Performing some PRF computations outside of 2PC allows to save on computation and bandwidth.</p>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>Note that the User's TLS connection retains the standard TLS security guarantees against any third-party adversary. </p>
|
||||
</blockquote>
|
||||
<p>To elaborate, recall how <a href="https://en.wikipedia.org/wiki/HMAC">HMAC</a> is computed (assuming |k| <= block size):</p>
|
||||
<pre><code>HMAC(k, m) = H((k ⊕ opad) | H((k ⊕ ipad) | m))
|
||||
</code></pre>
|
||||
<p>Notice that both H(k ⊕ opad) and H(k ⊕ ipad) can be computed separately prior to finalization. In this
|
||||
document we name these units as such:</p>
|
||||
<ul>
|
||||
<li><code>outer hash state</code>: H(k ⊕ opad)</li>
|
||||
<li><code>inner hash state</code>: H(k ⊕ ipad)</li>
|
||||
<li><code>inner hash</code>: H((k ⊕ ipad) | m)</li>
|
||||
</ul>
|
||||
<p>In TLS, the master secret is computed like so:</p>
|
||||
<pre><code class="language-python">seed = "master secret" | client_random | server_random
|
||||
a0 = seed
|
||||
a1 = HMAC(pms, a0)
|
||||
a2 = HMAC(pms, a1)
|
||||
p1 = HMAC(pms, a1 | seed)
|
||||
p2 = HMAC(pms, a2 | seed)
|
||||
ms = (p1 | p2)[:48]
|
||||
</code></pre>
|
||||
<p>Notice that in each step the key, in this case <code>PMS</code>, is constant. Thus both the <code>outer</code> and <code>inner hash state</code> can be reused for each step.</p>
|
||||
<p>Below is the description of the all the steps to compute the <code>PRF</code> both inside and outside the 2PC circuit.</p>

<li>To evaluate the circuit, the parties input their <code>PMS</code> shares. The circuit outputs:</li>
|
||||
</ol>
|
||||
<ul>
|
||||
<li>H(PMS ⊕ opad) called <code>PMS</code> <code>outer hash state</code> to <code>N</code> and</li>

<p>At the end of the TLSNotary session, both <code>U</code> and <code>N</code> know the authenticated AES <code>ciphertext</code>. </p>

</li>

<p><code>N</code> reveals his TLS session key shares to <code>U</code>.</p>

</li>
|

<li>

<p><code>N</code> picks a <code>seed</code> and uses it as the source of randomness to generate (in the semi-honest model) a privacy-free garbled circuit whose functionality is to accept the plaintext input, encrypt it, and output the ciphertext. </p>
|
||||
</li>
|
||||
<li>
|
||||
<p>With <code>p</code> as her circuit input, <code>U</code> receives input wire labels <code>IWLs</code> via Oblivious Transfer and then evaluates the circuit on those <code>IWLs</code>. The result of the evaluation are output wire labels <code>OWLs</code> which <code>U</code> does not know the decoding for.</p>

<p>In situations where <code>U</code> does not know in advance which subset of the public data she will be revealing later to the Verifier, <code>U</code> can commit to the Merkle tree of all her input wire labels (from Step 4 above).
