fhe-study

Implementations from scratch done while studying some FHE papers; do not use in production.

  • arith: contains $\mathbb{Z}_q$, $R_q=\mathbb{Z}_q/(X^N+1)$ and $R=\mathbb{Z}/(X^N+1)$ arithmetic implementations, together with the NTT implementation.
  • generalized-fhe: contains the structs and logic for RLWE, GLWE, GLev, GGSW, RGSW cryptosystems, which can be used by concrete FHE schemes.
  • bfv: https://eprint.iacr.org/2012/144.pdf scheme implementation
  • ckks: https://eprint.iacr.org/2016/421.pdf scheme implementation
