摘要：Actually, the NIST post-quantum cryptosystem standardization competition reached its third round with seven finalist candidates. And NIST invites the cryptographic community to analyzing the selected candidates. In this context, we contribute by creating a new blind digital signature protocol over our release of NTRU post-quantum cryptosystem. Our protocol can be a variant of FALCON digital signature scheme, which is among of those finalist candidates. Because of our NTRU release is additively homomorphic, we successfully blind and unblind the digital signature by adding a random message. We obtained good results; the speed performance of our protocol outperforms FALCON by a factor up to 27, with a stronger security level, and perfect correctness.
