异构网络中高效切换认证算法研究*

提出了一种异构网络高效切换认证算法，包括目标切换网络的软预测机制和基于上下文传递的融合认证机制。该算法在集中式认证机制的基础上进行改进，先通过层次邻居图法来快速确定目标切换网络，然后协商、传递会话密钥和信任材料等相关上下文信息，尽可能减少移动终端与家乡网络的认证交互，提高了切换重认证的效率。

Research on efficient algorithm of handoff and authentication inheterogeneous networks

This paper proposed an efficient algorithm of handoff and authentication in the heterogeneous networks,which contained two parts:soft prediction mechanism of target network for handoff and integrated authentication technique based on context transfer algorithm. Improved the algorithm based on centralized authentication method. The soft prediction mechanism could predict the target network quickly,so the integrated authentication technique could generate and transfer the security credentials and session key ...
