NTT-based fast lattice cryptography library

NFLlib is an efficient and open-source C++ library dedicated to ideal lattice cryptography. It is specialized in polynomial rings quotiented by a cyclotomic polynomial whose degree is a power of two. The library combines algorithmic optimizations Chinese Remainder Theorem, optimized Number Theoretic Transform together with programming optimization techniques SSE and AVX2 specializations, C++ expression templates, etc.
