Abstract: Aiming at the problems existed in security protection mechanism of IMS media level, a user-oriented uniform security frame in IMS media level is presented. The design scheme is given in detail, which provides users with security protection mechanism of media level flexibly. The security negotiation between encryption algorithm and the key at media level is implemented, and the communication security between users with end to end is guaranteed. Experimental results show this scheme is effective.

Key words: uniform security frame, security of media level, authentication, negotiation of algorithm
