A Quantum Identity Authentication Model Based on Twin-field
Inspired by the twin-field quantum key distribution protocol,a new quantum identity authentication protocol based on twin-field is propoed.With the help of third-party Charlie measurement,the authenticated session key is encoded using a hash function to achieve quantum identity authentication between the communicating parties.With the support of existing technology,the protocol is easy to implement and has strong feasibility.Through protocol analysis,it can be seen that the protocol can resist various known attacks and has high security.
