在代理签名方案中,代理签名人B被允许代表原始签名人A产生签名。然而,代理签名密钥的暴露可能是对代理签名方案的最具破坏性的攻击,因为任何对手都可以代表代理签名人对消息进行签名。在本文中,我们应用了Dodis等人的“的密钥隔离机制,提出了一种基于身份的密钥隔离代理签名方案(IBKIPS)。该方案是强密钥隔离和完全密钥隔离的。我们的方案还支持无限的周期数和随机访问密钥更新。
In proxy signature schemes, the proxy signer B is permitted to produce a signature on behalf of the original signer A. However, exposure of proxy signing keys can be the most devastating attack on a proxy signature scheme since any adversary can sign messages on behalf of the proxy signer. In this paper, we applied Dodis,et al.’s key-insulation mechanism and proposed an Identity-Based (ID-based) Key-Insulated Proxy Signature (IBKIPS) scheme with secure key-updates. The proposed scheme is strong key-insulated and perfectly key-insulated. Our scheme also supports unbounded period numbers and random-access key-updates.
