| 摘 要： | 针对托管代理机构存在最受信赖代理和由官方与民间代理共同组成两种情况,采用高安全性的椭圆曲线密码体制和高效率的基于状态树（t,n）门限秘密共享算法,分别设计了两类密钥托管方案.方案不仅实现了托管代理权限的灵活设置,还在防止用户、托管代理和监听机构欺诈的同时,提出并解决了密钥管理中心的欺诈问题.

| Abstract: | Aimed at two conditions of having trusted agent and making up of official and civil agents for escrow agency,the paper proposed key escrow schemes separately.The schemes were based on high security elliptic curve cryptosystem,and adopted the efficient threshold(t,n) secret sharing scheme of status-tree based.The two schemes not only placed the importance of escrow agents flexible,but also put forward the question of KMC′ cheating and its preventing method while they averted the cheating of users,escrow agent and supervision agency. |
