“…This QKA protocol does not require the help of a semi-trusted third party and some keys for authentication, unlike other QKA protocols. [32,34,35] Therefore, this protocol can reduce the complexity of authentication and save communication costs. Moreover, the security analysis also proves that our scheme is secure, reliable and feasible.…”

“…In recent years, some QKA protocols with identity authentication have been proposed. [31][32][33][34][35] In 2021, Zhu et al [33] presented a QKA protocol for authentication with the help of a semi-trusted third party, Trent, using GHZ-like states. In the protocol, Trent is assumed to be an internal eavesdropper, and the probability that he can eavesdrop the session key K AB is (1/2) L (L denotes the length of K AB ).…”

In order to make the quantum key agreement process immune to participant attacks, it is necessary to introduce the authentication in the communication process. A quantum key agreement protocol with identity authentication that exploit the measurement correlation of six-particle entangled states is proposed. In contrast to some recently proposed quantum key agreement protocols with authentication, this protocol requires neither a semi-trusted third party nor additional private keys in the authentication process. The entire process of authentication and key agreement can be achieved using only n six-particle entangled states, which saves communication costs and reduces the complexity of the authentication process. Finally, security analysis shows that this scheme is resistant to some important attacks.
