A Ticket-Based Anonymous Authentication Protocol for Mobile Roaming Networks

Ticket based anonymous authentication protocol is an important branch of anonymous authentication protocol research. In this paper, we propose an anonymous authentication protocol for large-scale practical applications, which satisfies that the interaction rounds are few and the efficiency is high. Analysis shows that the ticket can be used multiple times, the ticket generation phase does not need the participation of the foreign network server, and the roaming authentication phase does not need the participation of the home network server.
