基于密钥绝缘体制的多级代理签名体制

本文通过分析密钥绝缘体制和多级代理签名体制性质，发现他们之间存在某些本质上
的一致性，构造了一种新的多级代理签名体制。在这个签名体制中，代理签名者可以将原始 签名者的签名权利进一步委托给新的代理签名者，使得新代理签名者也能够代表原始签名者生成有效的数字签名。

Multiple grade proxy signature scheme based on key-insulated scheme CHENG Hua’qin, GAO Feng’xiu, MA Chuan’gui （Institute of Information Engineering, Information Engineering University, Zhengzhou, 450002） Abstract: Through analyzing the relation between key-insulated scheme and multiple grade proxy signature scheme, we find there are some identities and construct a new multiple grade signature scheme based on key-insulated scheme. In this scheme, a proxy signer can delegate his signing capabilities to a new proxy signer who could generate the signature on behalf of the original signer.
