摘要
随着移动通信技术广泛应用,现有移动核心网面临的安全威胁越来越突出。首先介绍了基于任务的访问控制模型(TBAC),进而研究并设计了一个适合在移动核心网中应用的基于任务的访问控制模型(M-TBAC)。该模型通过定义完整的模型元素和任务状态,能动态地控制网络中各个网元访问归属位置寄存器(HLR)的权限,具有较好的安全性和可扩展性。
With the wide applicationt of mobile communication technology, the security of mobile core net- work faces more and more threats. Firstly, the task--based access control model (TBAC) is introduced, and then a task--based access control model for mobile core network ( M - TBAC) is designed. The model defines the whole model elements and task status, and can control the privilege of each network unit access Home Location Register(HLR)dynamically.This model has good security and expansibility.
