Abstract :
VoIP is popularly used recently, and it will be more popular in the future. However, the security of VoIP is still a problem. There is no identity authentication in these services. According to the property of this system, a distributed trusted centers (TCS) system is proposed. In this paper, we propose a new solution for the authentication of all TCS. It keeps TCS legal, in the meanwhile, it makes the management of TCS convenient. This scheme prevents the replay attack and the identity impersonation attack. It also has perfect forward secrecy.
