Mobile TV is a key service in TD-SCDMA system,and the multimedia broadcast multicast service(MBMS) is introduced to 3GPP R6.Security is very important for multimedia multicast service of MBMS over TD-SCDMA system.In this paper,generic bootstrapping architecture(GBA) is introduced,TD-MBMS service security architecture and key management system over GBA for 3GPP system are analyzed.Advantages and deficiency of the security system are discussed,and the amelioration proposition for multicast service is given.
