Added

  • BFV/CKKS : added a check for minimum polynomial degree when creating parameters.
  • BFV : added the bfv.Element.Level method.
  • RING : test for sparse ternary sampler.

Changed

  • BFV/CKKS : pk is now (-as + e, a) instead of (-(as + e), a).
  • BFV : harmonized the EvaluationKey setter from SetRelinKeys to Set
  • CKKS : renamed BootstrappParams into BootstrappingParameters
  • CKKS : the Evaluator.DropLevel, Parameters.SetLogSlots and Element.Copy methods no longer return errors
  • RING : minimum poly degree modulus is 16 to ensure the NTT correctness.
  • RING : isPrime has been replaced by big.ProbablyPrime, which is deterministic for integers < 2^64.

Fixed

  • ALL : reduced cyclomatic complexity of several functions.
  • ALL : fixed all instances reporeted by staticcheck and gosec excluding G103 (audit the use of unsafe).
  • ALL : test vectors are now generated using the crypto/rand instead of math/rand package.
  • ALL : fixed some unhandled errors.
  • BFV/CKKS : improved the documentation: documentated several hardcoded values and fixed typos.
  • RING : fixed bias in sparse ternary sampling for some parameters.
  • RING : tests for the modular reduction algorithms are now deterministic.
