基于离散对数新的多重代理多重盲签名方案

New multi-proxy multi-signature scheme based on discrete logarithm

为了抵抗原始签名者内部攻击,代理授权信息以及签名信息不需要通过安全信道被安全传递,对提高签名方案的速率具有重要意义.在基于离散对数的多重代理多重盲签名方案的基础上,通过改进代理私钥,结合哈希求逆函数困难的方法,提出一种新的基于离散对数的多重代理多重盲签名方案.同时给出签名方案详细的授权过程、签名过程和验证过程.通过对方案的正确性和安全性分析,表明该方案具有不可否认性、不可链接性和盲性等特点.

To counter internal attacks from the original signers and eliminate the need for secure transmission of proxy authorization and signature information through a secure channel,it is of great significance to improve the speed of the signature scheme.Based on the discrete logarithm,a new multi-proxy multi-blind signature scheme was proposed by enhancing the proxy private key and combining it with the hardness of the hash inverse function.Detailed processes for authorization,signature,and verification were provided for the signature scheme.Through correctness and security analysis of the scheme,it was demonstrated that the scheme possesses features such as non-repudiation,unlinkability,and blindness.
