| Abstract: |
| Cooperative communication technology that is introduced into the 4th generation （4G）mobile communication system can bring new security hazards while improving system performance. Starting with excavating security flaws of protocols, this paper discusses security flaws in system by analyzing the security protocols and mechanisms of 4G system, summarizes the possible attack modes, and on this basis provides an authentication mechanism to avoid attack aiming at cooperative communication in 4G system. This mechanism can improve effectively security in the cooperative environment of 4G system. |
