基于身份和私钥隔离的密码系统
摘要
利用私钥隔离的思想来缓解基于身份密码系统中的私钥泄漏问题。首先构建了基于身份和私钥隔离的密码学原语
给出了这个原语的形式化安全模型
然后构造了一个具体的方案
并且证明了该方案的安全性。
Abstract
The method of key insulation to identity-cryptosystems was applied
for solving the key exposure problem ex-isting in the identity-based schemes were applied.After developing the formal secure model for identity-based and key insulated cryptosystems
a concrete scheme proved secure under this model was constructed.
