如何处理基于身份的签名中的密钥暴露问题是一个有价值的挑战。针对这一问题，本文将Dodis等人的密钥隔离机制应用于基于身份的签名场景，提出了一种基于身份的密钥隔离签名方案。该方案具有两个吸引人的特点：(1)强键绝缘；（ii）它是可证明的安全的，没有随机的预言。
It is a worthwhile challenge to deal with the key-exposure problem in identity-based signatures.To deal with this problem,this paper adopts Dodis,et al.'s key-insulation mechanism to identity-based signature scenarios, and proposes an identity-based key-insulated signature scheme.The proposed scheme enjoys two attractive features: (i)it is strong key-insulated;(ii)it is provably secure without random oracles.
