一种新的基于椭圆曲线的代理签名方案

数字签名和消息加密是信息安全的关键之一。文中利用椭圆曲线密码体制的高可靠性和短密钥等良好特性,提出一种指定接收者恢复消息的代理签名方案,并进行安全性和性能分析。该方案不需要使用专门的安全传输通道及分发代理签名密钥,而且将签名和加密较好地结合起来,可应用于电子现金和移动电子商务等场合。

A Novel Proxy Signature Scheme Based on ECC

The digital signature and encryption are key problems of the message security.A novel efficient signature scheme based on the elliptic curve with the designed receiver and message recovery is discussed.It makes full use of the characteristics of the elliptic curve cryptography.The scheme has two advantages that the proxy signature key can be transmitted without secure channels and only the designed receiver can recover the message.This scheme can be applied in the occasions like electronic cash and mobile E-business.
