Abstract

Existing mutual authentication quantum key negotiation protocols commonly use entangled states to enhance the protocol's security and efficiency, but preparing these states is difficult, and practical implementation remains challenging. To address this, this paper proposed a new quantum key negotiation protocol that achieved mutual identity authentication between two parties. The protocol enabled identity authentication and key agreement by encoding identity and private key information into orthogonal product states via unitary operations, and decoding them based on the publicly announced initial states and measurement bases. Compared with entangled states, orthogonal product states are easier to prepare, and their nonlocality ensures that eavesdroppers cannot obtain secret information by measuring particles transmitted in the protocol. Security analysis showed that the protocol effectively resisted participant attacks and external attacks, such as targeting identity authentication impersonation attacks, Trojan horse attacks, intercept-resend attacks, measure-resend attacks, and entangle-measure attacks, thereby enhancing the protocol's security and application value.
