Quantum identity authentication using a Hadamard gate based on a GHZ state

Abstract: According to the properties of Hadamard gate and GHZ state, a quantum authentication protocol with transferable information is proposed. This protocol has higher security and integrity. Especially, the direct appearance of the key and the transmitted information is not required for both quantum and classical channels. In addition, the protocol realizes the key update in the process of identity authentication, which can automatically generate the key needed for the next information transmission. We expect that … Show more
