Examples
- Secondly , we described the fundamental concepts and properties of group signature scheme and some general digital signatures that can be used to construct group signature amply , and presented a group signature scheme based on the integer factorization . thirdly , we explained the fundamental concepts and properties of authorized group signature in detail and propounded a secure authorized group signature based upon the discrete logarithm . finally , we illuminated electronic payment system in e - commerce and designed a simple and high secure electronic cash system with multiple banks based on group signature
首先,对群签名体制的研究背景、意义以及发展现状进行了介绍;接着针对群签名体制的基本概念和性质以及可用于构造群签名的一些普通的数字签名体制进行了详细描述,并基于大整数分解问题给出一个群签名方案;同时还对授权群签名的基本概念和必须满足的基本性质进行了详细说明,并且基于离散对数问题给出一个安全的授权群签名方案;最后,对电子商务中的一个重要组成部分? ?电子支付系统进行了详细的阐述,利用群签名技术设计出一个简单、高安全性的多银行电子现金系统方案。 - The primary advantage that elliptic curve systems have over systems based on the multiplicative group of a finite field ( and also over systems based on the intractability of integer factorization ) is the absence of a subexponential - time algorithm ( such as those of index calculus type ) that could find discrete logs in these groups
与基于有限域的乘法群系统(及基于整数分解的难解性之上的系统)相比,椭圆曲线系统的优势在于,迄今为止还没找到这类群上离散对数的次指数时间算法(如微积分类)
