摘要:

为了减轻基于身份的签名系统中密钥泄漏所带来危害,运用Weng等的门限密钥隔离机制设计了一个基于身份的门限密钥隔离签名方案.所提方案的安全性证明是基于标准模型的,即不需要随机预言机.

Abstract:

To minimize the damage caused by key-exposure in ID-based signature scenarios, this paper  proposed an identity-based threshold key-insulated signature scheme by using Weng et al.’s threshold key-insulated mechanism. The formal proof of security was presented in the standard model, i.e. without random oracles.

Key words: threshold keyinsulated, identitybased, signature
