基于二次剩余的新型盲签名方案

盲签名在密码学中扮演着重要角色,许多密码研究者在这个领域做了研究,并设计了一些方案。但是,这些方案大多是基于离散对数、双线性配对或RSA体制。本文设计了一种基于二次剩余的盲签名方案,该盲签名方案满足盲签名的两个重要的基本安全需求,并且由于计算效率较高,它比较适用于移动通信等计算能力受限的场合。

A New Blind Signature Scheme Based on the Quadratic Residue

Blind signature plays an important role in cryptography. Many cryptographic researchers have made considerable achievement in this field,and have designed many schemes. However,to our knowledge,most of the existing blind signature schemes are based on the discrete logarithm problem,blinear pairings,or the RSA cryptosystem. In this paper,we propose a new blind signature scheme based on the quadratic residue. This blind signature scheme can meet the two important basic security requirements of blind signature...
