Embodiments of the present invention disclose a method and an apparatus for security algorithm selection processing, a network entity, and a communication system. The method includes: receiving a service request message sent by user equipment; and according to a security protection requirement of the service request message, selecting a security algorithm from a security algorithm list supported by both the user equipment and a network entity, where security algorithm lists supported by the user equipment and/or the network entity are set separately based on different security protection requirements, or security algorithm lists supported by the user equipment and the network entity are used for indicating security capability of the user equipment and the network entity respectively. In the embodiments of the present invention, different security algorithms may be selected according to security protection requirements of different service request messages, so that different security protection is performed for the corresponding service, which improves security of the service. Moreover, in a communication system, complexity of each algorithm and an overhead occupied by each algorithm are considered comprehensively, and therefore, performance of the communication system is improved when effective security protection is performed on the service. |
