+# Contributor Covenant Code of Conduct
+
+## Our pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting us anonymously through [this form](https://forms.gle/569j3cZqGRFgrR3u9).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+

-Mitigation for side channel attacks have not yet been implemented in TFHE-rs,
+The default parameters for the TFHE-rs library are chosen considering the IND-CPA security model, and are selected with a bootstrapping failure probability fixed at p_error = $2^{-64}$. In particular, it is assumed that the results of decrypted computations are not shared by the secret key owner with any third parties, as such an action can lead to leakage of the secret encryption key. If you are designing an application where decryptions must be shared, you will need to craft custom encryption parameters which are chosen in consideration of the IND-CPA^D security model [1].

+# FHE boolean Trivium implementation using TFHE-rs
+
+The cleartext boolean Trivium is available to be built using the function `TriviumStream::<bool>::new`. 
+This takes as input 2 arrays of 80 bool: the Trivium key and the IV. After initialization, it returns a TriviumStream on 
+which the user can call `next`, getting the next bit of the cipher stream, or `next_64`, which will compute 64 values at once,
+using multithreading to accelerate the computation.
+
+
+Quite similarly, the function `TriviumStream::<FheBool>::new` will return a very similar object running in FHE space. Its arguments are
+2 arrays of 80 FheBool representing the encrypted Trivium key, and the encrypted IV. It also requires a reference to the the server key of the 
+current scheme. This means that any user of this feature must also have the `tfhe-rs` crate as a dependency.
+
+
+Example of a Rust main below:
+```rust
+use tfhe::{ConfigBuilder, generate_keys, FheBool};
+use tfhe::prelude::*;
+use tfhe_trivium::TriviumStream;
+
+fn get_hexadecimal_string_from_lsb_first_stream(a: Vec<bool>) -> String {

+	let mut hexadecimal: String = "".to_string();
+	for test in a.chunks(8) {

+# FHE byte Trivium implementation
+
+The same objects have also been implemented to stream bytes instead of booleans. They can be constructed and used in the same way via the functions `TriviumStreamByte::<u8>::new` and 
+`TriviumStreamByte::<FheUint8>::new` with the same arguments as before. The `FheUint8` version is significantly slower than the `FheBool` version, because not running 
+with the same cryptographic parameters. Its interest lie in its trans-ciphering capabilities: `TriviumStreamByte<FheUint8>` implements the trait `TransCiphering`, 
+meaning it implements the functions `trans_encrypt_64`. This function takes as input a `FheUint64` and outputs a `FheUint64`, the output being
+encrypted via tfhe and trivium. For convenience we also provide `trans_decrypt_64`, but this is of course the exact same function.
+
+Other sizes than 64 bit are expected to be available in the future.
+
+# FHE shortint Trivium implementation
+
+The same implementation is also available for generic Ciphertexts representing bits (meant to be used with parameters `PARAM_MESSAGE_1_CARRY_1_KS_PBS`). It uses a lower level API 
+of tfhe-rs, so the syntax is a little bit different. It also implements the `TransCiphering` trait. For optimization purposes, it does not internally run on the same 
+cryptographic parameters as the high level API of tfhe-rs. As such, it requires the usage of a casting key, to switch from one parameter space to another, which makes 
+its setup a little more intricate.
+
+Example code:
+```rust
+use tfhe::shortint::prelude::*;
+use tfhe::shortint::CastingKey;
+use tfhe::{ConfigBuilder, generate_keys, FheUint64};
+use tfhe::prelude::*;
+use tfhe_trivium::TriviumStreamShortint;

+	let ksk = CastingKey::new((&client_key, &server_key), (&hl_client_key, &hl_server_key));
+
+	let key_string = "0053A6F94C9FF24598EB".to_string();

+

+		for j in 0..8 {
+			key[8*(i>>1) + j] = val % 2;
+			val >>= 1;
+		}
+	}
+

+

+		let trans_ciphered_message = trivium.trans_encrypt_64(ciphered_message.pop().unwrap(), &hl_server_key);
+		vec.push(trans_ciphered_message.decrypt(&hl_client_key));
+	}
+
+	let hexadecimal = get_hexagonal_string_from_u64(vec);
+	assert_eq!(output_0_63, hexadecimal[0..64*2]);
+}
+```
+
+# FHE Kreyvium implementation using tfhe-rs crate
+
+This will work in exactly the same way as the Trivium implementation, except that the key and iv need to be 128 bits now. Available for the same internal types as Trivium, with similar syntax.
+
+`KreyviumStreamByte<FheUint8>` and `KreyviumStreamShortint` also implement the `TransCiphering` trait.
+
+# Testing
+
+If you wish to run tests on this app, please run `cargo test -r trivium -- --test-threads=1` as multithreading provokes interferences between several running 
+Triviums at the same time.

+# TFHE Cuda backend
+
+## Introduction
+
+The `tfhe-cuda-backend` holds the code for GPU acceleration of Zama's variant of TFHE.
+It implements CUDA/C++ functions to perform homomorphic operations on LWE ciphertexts.
+
+It provides functions to allocate memory on the GPU, to copy data back 
+and forth between the CPU and the GPU, to create and destroy Cuda streams, etc.:
+- `cuda_create_stream`, `cuda_destroy_stream`
+- `cuda_malloc`, `cuda_check_valid_malloc`
+- `cuda_memcpy_async_to_cpu`, `cuda_memcpy_async_to_gpu`
+- `cuda_get_number_of_gpus`
+- `cuda_synchronize_device`
+The cryptographic operations it provides are:
+- an amortized implementation of the TFHE programmable bootstrap: `cuda_bootstrap_amortized_lwe_ciphertext_vector_32` and `cuda_bootstrap_amortized_lwe_ciphertext_vector_64`
+- a low latency implementation of the TFHE programmable bootstrap: `cuda_bootstrap_low latency_lwe_ciphertext_vector_32` and `cuda_bootstrap_low_latency_lwe_ciphertext_vector_64`
+- the keyswitch: `cuda_keyswitch_lwe_ciphertext_vector_32` and `cuda_keyswitch_lwe_ciphertext_vector_64`
+- the larger precision programmable bootstrap (wop PBS, which supports up to 16 bits of message while the classical PBS only supports up to 8 bits of message) and its sub-components: `cuda_wop_pbs_64`, `cuda_extract_bits_64`, `cuda_circuit_bootstrap_64`, `cuda_cmux_tree_64`, `cuda_blind_rotation_sample_extraction_64`
+- acceleration for leveled operations: `cuda_negate_lwe_ciphertext_vector_64`, `cuda_add_lwe_ciphertext_vector_64`, `cuda_add_lwe_ciphertext_vector_plaintext_vector_64`, `cuda_mult_lwe_ciphertext_vector_cleartext_vector`.
+
+## Dependencies
+
+**Disclaimer**: Compilation on Windows/Mac is not supported yet. Only Nvidia GPUs are supported. 
+
+- nvidia driver - for example, if you're running Ubuntu 20.04 check this [page](https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-20-04-focal-fossa-linux) for installation
+- [nvcc](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html) >= 10.0
+- [gcc](https://gcc.gnu.org/) >= 8.0 - check this [page](https://gist.github.com/ax3l/9489132) for more details about nvcc/gcc compatible versions
+- [cmake](https://cmake.org/) >= 3.24
+
+## Build
+
+The Cuda project held in `tfhe-cuda-backend` can be compiled independently from TFHE-rs in the following way:
+```
+git clone git@github.com:zama-ai/tfhe-rs
+cd backends/tfhe-cuda-backend/cuda
+mkdir build
+cd build
+cmake ..
+make
+```
+The compute capability is detected automatically (with the first GPU information) and set accordingly.
+If your machine does not have an available Nvidia GPU, the compilation will work if you have the nvcc compiler installed. The generated executable will target a 7.0 compute capability (sm_70).
