北京邮电大学硕上学位论文 北京邮电大学硕上学位论文 IMS核心网络认证框架研究 RESEARCH ON AUTHENTICATION FRAMEWORK OF IMS CORE NETWORK ABSTRACT IMS，i．e．IP Multimedia Subsystem，iS a kind of state of art Multimedia business． It can satisfy the novelty and diversi fication of the multimedia business products． Although IMS has not been widely deployed in commercial scenario．some of the most famous Telecommunication equipment providers have released their newly developed IMS—based Product．Some operators are undertaking their test network plan using IMS techniques．During the process of network evolution and convergence．the security aspect of IMS is especially important．This topic divides IMS into 3 layers，which are access 1evel，core node 1evel and business 1evel．which compromise the 3 IMS core network Authentication framework．This framework iS based on the research on the standard and draft of 3GPP，TISpAN，ITU—T and IETF， l paid attention to the description of client access authentication．core nodes authentication and the integrated IMS architecture Trustworthy solution after the detail analysis of the protoc01．architectures and services of NGN and IMS techniques．Aiming at the multiple and open IMS services，I present a full service authentication architecture with 3 GPP／3 GPP2 GAA as reference． Among the authentication technologies，access authentications are described both as mobile access and fixed network access．Core network analysis includes mutual authentication between P—CSCF and S—CSCF．and trusted IMS as well． Business authentication includes the bootstrapping authentication framework of fixed network access to IMS． KEY WORDS：IP Multimedia Subsystem，Authentication，Trust compute， Authenti cation and Key Agreement 独创性(或创新性)声明 独创性(或创新性)声明 本人声明所呈交的论文是本人在导师指导下进行的研究工作及取得的研究 成果。尽我所知，除了文中特别加以标注和致谢中所罗列的内容以外，论文中不 包含其他人已经发表或撰写过的研究成果，也不包含为获得北京邮电大学或其他 教育机构的学位或证书而使用过的材料。与我一同工作的同志对本研究所做的任 何贡献均已在论文中作了明确的说明并表示了谢意。 关于论文使用授权的说明 学位论文作者完全了解北京邮电大学有关保留和使刚学位论文的规定，即：研究生在校 攻读学位期间论文：r：作的知识产权单位属北京邮电人学。学校有权保留并向国家有关部 l、J或机构送交论文的复印
