An anonymous authentication scheme for mobile communication without trusted third party

In order to provide anonymity services for mobile network users, ensure the confidentiality of the user´s identity, we raised an anonymous authentication scheme without trusted third party. The scheme not only solves the problem of user´s anonymity in the whole network, but also can open the message to track users when necessary, and achieve controllable anonymity. The scheme is implemented by difficult discrete logarithm problem and partially blind signature technology. Through the program´s correctness, security analysis, the program is safe and reliable.
