There are many security defects in existing mobile communication systems, such as unidirectional authentication and cipher key transmission in plaintext. With the expansion of the mobile communication services, the mobile security becomes more and more important, but the existing communication systems can not prevent hostile attacks to supply high-quality service because of their defects in security. To solve these problems, we propose a new Security Architecture for Mobile Communication (SAMC), which employs new authentication protocols, chooses different encryption algorithms for different requirements and implements integrity control mechanism. Good security is developed in an open environment with the collaboration of experts. It has the robust security and the outstanding performance, just a slight and acceptable loss.
