An anonymous authentication scheme for mobile communication

In order to enable mobile network to provide anonymity services, ensure the confidentiality of the user´s identity, whereabouts and other information, we raised an anonymous authentication scheme. The scheme solves the problem of user´s anonymity not only in roaming network, but also in adscription network. The scheme bases on binary tree theory and the knowledge proof, and combines divisible e-cash theory to implement. Theoretical analysis and experimental results demonstrate using the scheme can provide users for anonymity service not only in roaming network, but also in adscription network.
