在介绍IPSec协议基本原理的基础上,分析了CD-MA2000系统在引入分组数据业务后的安全需求,详细描述了在CDMA2000分组数据服务节点(PDSN)上使用IPSec为移动IP提供安全保护的过程,并给出一个在PDSN上实现IPSec的模型。
Based on the introduction of the basic principle of IPSec protocol, the security requirements of CD-MA2000 system after the introduction of packet data service are analyzed. The process of using IPSec to provide security protection for mobile IP on CDMA2000 Packet Data Serving Node (PDSN) And gives a model of implementing IPSec on PDSN.
