基于小型核心网的LTE鉴权的一种新实现

New Realization of LTE Authentication Based on Miniature Core Network

LTE移动通信系统采用3GPP认证与密钥协商机制来加强对用户的保护。为了节约成本,在用户容量较小和一般性研发测试的环境下,引入一种小型核心网来满足特殊的需求。鉴权过程需要核心网向HSS服务器申请鉴权参数,通过一定的算法来对UE进行鉴权。主要提出了一种针对这种小型核心网的鉴权实现方法,将计算鉴权参数的过程集成到核心网。该实现方法不需要HSS服务器的参与,实现更简单方便,节约开发成本。

The LTE Mobile Telecommunication System （UMTS） adopts 3GPP authentication and key agreement （3GPP AKA） mechanism to strengthen the protection of the user. In order to save costs, a miniature core network is introduced to fulfill the special requirement, when only smaller user capaci- ty and normal test need. Authentication procedure require the core network apply for authentication parameters, which is used in UE authentication by some specific algorithms, from HSS sever. This paper aims at providing a new method which will embed the computational process of authentication parameters inside the miniature core network to realize authentication based on miniature core network. In this way, the realization of authentication will be more simple and convenience by getting rid of the HSS sever ,what＇s more, the costs of the research will also be reduced.
