| Abstract: | The authentication and authorization are analyzed and researched when a 3G user is accessed in this paper. The 3G security system architecture is introduced firstly; then the detailed analysis is made about the process of authentication and authorization for 3G, the process and method of encryption and integrity protection for user's information, and the negotiation mechanism of privacy key, at the same time, the potential vulnerabilities of this mechanism is given; and at last, the mutual security and the conversion algorithm of security context for 2G and 3G are classified and anatomized. |
