基于Bell态纠缠交换的身份认证协议

his paper presented a new quantum authentication protocols. The protocol took Bell state as the transmission carrier and used Bell state entanglement swapping and Bell basis measurement to authenticate communication users. There was no need to do any unitary transformation in the transmission of two Bell states. Only need to perform Bell basis measurement and bitwise XOR operation could achieve the transmission of information. Throughout the process, the quantum carrier was simple and easy to implement. In addition, this paper also verified the correctness of this protocol.
