为了研究3G(第三代移动通信技术)安全协议的发展现状,该文以3G实体认证协议为重点研究内容,广泛地分析了3GPP(第三代合作伙伴计划)提出的一系列相关安全协议及技术规范,给出了基于独立同分布概率理论的认证数据流量数学分析模型。该文分析了现存3GPP安全协议在用户接入过程中存在的单向认证安全缺陷,以及认证数据流量分布不均、体系过于复杂的缺点。在此基础上通过研究IBC(基于标识的密码技术)理论及技术,为3G安全认证技术的发展提出了新的技术解决途径,为进一步深入研究提供了详实的分析材料。
In order to study the status quo of 3G (third generation mobile communication technology) security protocol, this paper focuses on the 3G entity authentication protocol and analyzes a series of related security protocols proposed by 3GPP (3rd Generation Partnership Project) Technical specifications, and gives the mathematical analysis model of authentication data flow based on the independent and identically distributed probability theory. This paper analyzes the defects of the unidirectional authentication security existing in the existing 3GPP security protocols during the user access process, as well as the uneven distribution of the authentication data traffic and the complicated system. Based on this, IBC (Identity-Based Cryptography) theory and technology are put forward to provide new technical solutions for the development of 3G security authentication technology and provide detailed analysis materials for further research.
