 # Test vectors for TFHE
 These test vectors are generated using [TFHE-rs](https://github.com/zama-ai/tfhe-rs), with the git tag `tfhe-test-vectors-0.2.0`.
 
-They are TFHE-rs objects serialized in the [cbor format](https://cbor.io/). You can deserialize them using any cbor library for the language of your choice. For example, using the [cbor2](https://pypi.org/project/cbor2/) program, run: `cbor2 --pretty toy_params/lwe_a.cbor`.

-You will find 2 folders with test vectors for different parameter sets:

-- `toy_params`: insecure parameters that yield smaller values
+There are 2 folders with test vectors for different parameter sets:
+- `valid_params_128`: valid classical PBS parameters using a Gaussian noise distribution, providing 128-bits of security in the IND-CPA model (i.e., the probability of failure is smaller than 2^{-64}).
+- `toy_params`: insecure parameters that yield smaller values to simplify the bit comparison of the results.
 
-The values are generated for the keyswitch -> bootstrap (KS-PBS) atomic pattern. The cleartext inputs are 2 values, A and B defined below.
+The values are generated to compute a keyswitch (KS) followed by a bootstrap (PBS). The cleartext inputs are 2 values, A and B defined below.
 
 All the random values are generated from a fixed seed, that can be found in the `RAND_SEED` constant below. The PRNG used is the one based on the AES block cipher in counter mode, from tfhe `tfhe-csprng` crate.
 
-The programmable bootstrap is applied twice, with 2 different lut, the identity lut and a specific one (currently a x2 operation)
+The bootstrap is applied twice, with 2 different lut, the identity lut and a specific one computing the double of the input value (i.e., f(x) = 2*x).

+Ciphertexts with the `_karatsuba` suffix are generated using the Karatsuba polynomial multiplication algorithm in the blind rotation, while default ciphertexts are generated using an FFT multiplication.
+This makes it easier to reproduce bit exact results.

 # FHE shortint Trivium implementation
 
-The same implementation is also available for generic Ciphertexts representing bits (meant to be used with parameters `V1_5_PARAM_MESSAGE_1_CARRY_1_KS_PBS_GAUSSIAN_2M128`).
+The same implementation is also available for generic Ciphertexts representing bits (meant to be used with parameters `V1_6_PARAM_MESSAGE_1_CARRY_1_KS_PBS_GAUSSIAN_2M128`).
 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.
