摘　　要：目前,彩信系统存在的安全问题,如彩信病毒,冒充用户等给彩信业务的应用带来了极大的威胁。本文结合移动通信系统的特点,提出了基于安全证书的多媒体信息客户端安全解决方案。该方案实施与彩信应用层,利用彩信系统现有的传输通道加以改进完成彩信客户端之间的双向认证,加密,密钥协商和更新。通过一些关键技术的引用,如由入侵检测结果和用户可信度决定的动态密钥生存期,后台彩信查询对端公钥证书的方法,MSISDN号作为对方身份验证的加强等保证安全彩信的安全可靠性同时也提高其工作效率。present more and more security problems existing in multimedia message system like MMS virus and fake client are threatening MMS service development. Considering Mobile network characteristics, we present a end to end security solution based on certificate which is broadly applied in MMS terminals. Based on current MMS transmission system, the solution could provide the dual mode authentication, encryption, key creation and updating to improve the MMS secrity. With the introduce of some key technologies, i.e. Request the certificate in background mode, Key lifetime changed by reliablity and environment security status, MSISDN used to enhanced MMS certification, Packaging MMS security message, the MMS systems reliability, security, efficiency are improved greatly.
