摘要
本文在分析目前密码管理协议的基础上,针对DSPS系统的需求和特点设计并实现一种密钥管理协议。目前普遍的密钥交换算法,采用时间戳或随机数来确认产生的会话密钥的新鲜性,本文引入了新的密钥产生函数KHF,保证通信双方只有同步交换信息时,才能得到正确的会话密钥。
Basing on the analysis of the popular key management protocols,we design and implement a novel key management protocol aiming at the requirements of DSPS system. Current key exchange algorithm commonly uses timestamps or random number to verify the freshness of the new session key. In this article we use KHF to generate the session key, so that users are guaranteed to get correct session key, only when information exchange is in synchronization and in security.
