TFHE-rs version 0.2.2

TFHE-rs v0.2.2 features:

(core) Fix rng
(core) Disable split PBS u128 implementation
(boolean) Add BooleanEngine::replace_thread_local

TFHE-rs version 0.2.1

TFHE-rs v0.2.1 features:

• (integer) Fix default multiplication
• (integer) Improve Min/Max performance
• (hl_api) Add trivial_ciphertext to the high-level API
• (hl_api) Fix the number of blocks for FheUint32
• (Doc) Benches updated

TFHE-rs version 0.2.0

TFHE-rs v0.2.0 includes:

• New modules:

  • An integer module to manage homomorphic unsigned integers encrypting messages up to 256 bits;
  • A high-level API, including predefined homomorphic types and overloaded operators. A C binding is also available;

• New features in all modules:

  • Encryption key choice: In shortint and integer, the large LWE key is used by default. It is now possible to encrypt with the small one;
  • A smaller public encryption key: As a consequence of the previous point, a smaller secret encryption key implies a smaller public key;

• New features in core_crypto:

  • The ability to compute a PBS over 128-bit ciphertexts;
  • The choice of the ciphertext modulus: This can now be modified to use any powers of two smaller than 2^128;
  • Parallel Programmable Bootstrapping: A parallelized version of the bootstrapping is now available.

TFHE-rs version 0.1.12

TFHE-rs 0.1.12 features:

• fix a bug in avx512 specific code

TFHE-rs version 0.1.11

TFHE-rs 0.1.11 features:

TFHE-rs version 0.1.9

TFHE-rs 0.1.9 features:

• fix documentation about shortint default parameters
• fix a bug in generate_lwe_private_functional_packing_keyswitch_key (the parallel variant was not affected) which yielded incorrect keys

TFHE-rs version 0.1.8

TFHE-rs 0.1.8 features:

• Use karatsuba polynomial multiplication when appropriate, significantly boosting keygen times
• Upgrade concrete-csprng to 0.3.0 replacing the deprecated aes_soft crate from the dependency tree by the aes crate

TFHE-rs version 0.1.6

TFHE-rs 0.1.6 features:

• A low-level, cryptographic library that implements Zama’s variant of TFHE, including programmable bootstrapping;
• An implementation of the original TFHE boolean API, which can be used as a drop-in replacement for other TFHE libraries;
• A short integer API, which enables exact, unbounded FHE integer arithmetics with up to 8 bits of message space;
• A public key encryption implementation for TFHE;
• Ciphertext and server key compression for efficient data transfer;
• A full Rust and C API, and a client-side WASM API.
