Paper Abstract

We propose two interactive identification protocols based on a general construction of quantum public-key cryptosystem. Basic protocol contains set-up phase and authentication phase. Participants do operation with quantum computing of Boolean function in two-round transmission of authentication phase. Basic one only ensures completeness and soundness, but leaks information about private-key. We modify basic protocol with random string and random Boolean permutation. After modification, both transmitted states in two-round transmission can be proved to be ultimate mixed states. No participant or attacker will get useful information about private-key by measuring such states. Modified protocol achieves property of zero-knowledge.
