摘要:

目前安全的椭圆曲线密码体制中,其安全性是基于椭圆曲线离散对数的难解性,安全指数是全指数的,本文根据椭圆曲线密码体制的安全性,并结合代理签名和多重盲签名的特性,设计了一种基于椭圆曲线密码体制的代理多重盲签名方案。该方案步骤简单、安全性高,能达到代理委托签名的任务和多重签名的要求,并且该签名方案具有盲签名的特性,能在未知对方身份的情况下进行身份验证,并经过严密的证明得出该签名方案是实用、安全和有效的。

Abstract: At present, the security of Elliptic Curve Cryptography is based on the elliptic curve discrete logarithm difficulty, and its safety index is full index. According to the safety, we design an Elliptic Curve Cryptosystem proxy multiple blind signature that combes with the proxy signature and the multiblindsignature features.This signature scheme has simple steps, highlevel security,and achieves the task of agency and the requirements of multisignature. And this signature scheme has blind signature characteristics, can verify the identity in the case of unknown authentication, and a rigorous proof proves this signature scheme is practical,safe and effective.
