Contribution

It presents a novel quantum no-key protocol with mutual authentication that can be securely reused, expanding quantum cryptography capabilities.

Findings

Protocol is unconditionally secure

Authentication key can be reused permanently

Utilizes quantum computation of Boolean permutation

Abstract

We realize shamir's no-key protocol via quantum computation of Boolean permutation and private quantum channel. The quantum no-key (QNK) protocol presented here is one with mutual authentications, and proved to be unconditionally secure. An important property of this protocol is that0 its authentication key can be reused permanently.
