v0.3.0

TFHE-go v0.3.0 arrives with major new features, performance improvements, bug fixes and more!

  • Implement Multi-Key TFHE.
  • Implement public key encryption for some parameters.
  • Change representation of FourierPoly coefficients: now it is represented with 4 blocks of float, making AVX2 path faster.
  • Reduce FFT in Bootstrapping. Now Programmable Bootstrapping is 1.5~2.0x faster.
  • Optimize numerous methods and functions, including AVX2 implementations.
  • Rename methods and variables to be more concise and meaningful.

v0.2.7
  • Implement EBS(Extended Bootstrapping) from [LY23]. This significantly improves bootstrapping performance and key size, especially for large parameters.
  • Fix polynomial multiplication for small degree polynomials.
  • Fix panic in SampleExtract.
  • Fix to use cyclic FFT, rather than negacyclic FFT.

v0.2.5
  • Breaking Change: tfheb package is now integrated to tfhe. tfheb.XXX structures are now renamed to tfhe.BinaryXXX.
  • Add option to choose bootstrapping order in Parameters. This matches TFHE-rs implementation.
  • Revert LWESmallDimension to LWEDimension to reduce confusion.
  • Optimize default parameters so that it matches security level of TFHE-rs.
  • Optimize codepath for BlockSize 1, which matches the original bootstrapping of TFHE.

v0.2.4
  • Breaking Change: Change the order of KeySwitch and BlindRotate. This allows for better parameters, and is consistent with TFHE-rs. LWEDimension is renamed to LWESmallDimension, and LWELargeDimension is now LWEDimension.
  • Breaking Change: Rename Hoisted methods to Decomposed.
  • Breaking Change: Remove defined types from num package.
  • Add custom binary serialization to all common entities. Now all plaintexts, ciphertexts and keys implement io.WriterTo/io.ReaderFrom, and encoding.BinaryMarshaler/encoding.BinaryUnmarshaler interfaces.
  • Optimize CSPRNGs. Now EvaluationKey generation is ~50% faster.

v0.2.3
  • Breaking Change: Rename DecompositionParameters to GadgetParameters for concise code
  • Add Clear() methods
  • Add binary marshalling/unmarshalling to parameters. Now all common entities (plaintexts, ciphertexts, keys) can be marshalled/unmarshalled into binary using encoding/gob.
  • Fix incorrect gaussian sampling
