摘要:Since 2016, the National Institute for Standards and Technology (NIST) launched a post-quantum standardization project. Now the competition reaches its third round, and NIST inviting the cryptographic community to participate by improving and analyzing the finalist candidates. On our side, we contribute by creating an improved release of NTRU Lattice-Based post-quantum key exchange (KEM) scheme, called �NTRUrobust�; with parameters set that meet the category 5 security level defined by the NIST. NTRUrobust used our own Fast Modular Multiplication algorithm (FMMA) and the Number Theoretic Transform algorithm (NTT) together for speeding-up the polynomials multiplication in the cryptographic process. We obtain drastic results; our release is faster by factor up to 93 times than NTRUphs821 release proposed by the NTRU team. NTRUrobust warrants strong security level, perfect correctness, and great flexibility for eventual future extensions.
