摘要: 目前的门限代理签名方案几乎都是基于离散对数问题的,基于RSA密码体制的门限代理签名方案几乎很少。借助简单秘密共享思想构造了一个新的、安全有效的RSA门限代理签名方案,该方案满足门限代理签名方案的安全性的同时,计算量小,易实现。

Abstract: The proposed threshold proxy signature schemes have been based on the discrete logarithm problem,and there are few RSA-based schemes.Using the simple threshold RSA method,a new secure RSA-based threshold proxy signature scheme is proposed.This scheme has the properties of threshold proxy signature scheme.The fast computation and simple operation are also the features of this scheme.

Key words: RSA cryptosystems, threshold proxy signature, simple secret sharing
