Also, there are possibly better BS algorithms by now. + +## How it works + +Well, the actual program is not there yet. There's just some code to facilitate +polynomial multiplication in a ring modulo X^m+1 over a modulo field with +non-canonical range — [-(n-1)/2, (n-1)/2] rather than [0, n-1]. Interestingly, +only modulo operations in the latter range seem to be directly supported in +FLINT as of today. + +## Building + +Please consult the included Makefile :) + +- [1] https://eprint.iacr.org/2008/322 +- [2] https://flintlib.org/ |
