一种基于RSA密码体制的强代理签名方案

A Strong Proxy Signature Scheme Based on RSA Cryptosystem

提出了一种基于RSA密码体制的代理签名方案.与其它方案相比,该方案中的原始签名人与代理签名人的安全参数互不相同,并具有无需以安全方式传送代理秘钥和容易实现相互代理的特点.

In this paper, a new proxy signature scheme based on RSA cryptosystem is proposed. Comparing with other proxy signature schemes, it does not need to have the same security parameters for the original signer and the proxy signer. It has the new properties of delivering the proxy signature keys in no secure manner and obtaining easily to delegate signing power each other between the original signer and the proxy signer.
