摘要

本文提出了一种利用零知识协议和密钥交换来提供认证和机密性的新方法。零知识证明协议是密码学的重要组成部分,近年来越来越受到学者们的关注。它的应用范围越来越广,在数学、网络安全等多个领域都取得了进展。这个简单的协议基于零知识证明,通过它,用户可以向身份验证服务器证明他拥有密码,而不必将密码以明文或加密格式发送给服务器。这是一种协议,其中一方(即检查员)获得的数据允许他/她核实陈述是否属实,但不透露任何额外信息。本文首先讨论了零知识协议的知识证明系统和用户之间的密钥交换,然后将其修改为具有保密密钥交换的认证方案。整个协议涉及到两个用户的相互识别,交换一个随机的公共密钥或会话密钥来验证公钥。

An Alternative Methodology for Authentication and Confidentiality Based on Zero Knowledge Protocols Using Diffie-Hellman Key Exchange
This paper presents a concept for a new method to provide the authentication and confidentiality using zero knowledge protocol and key exchange. Zero knowledge proof protocol is a essential component of cryptography, which in recent years has increasingly popular amongst scholars. Its applications have widened and it has made inroads in several areas including mathematics and network safety and so on. This simple protocol based on zero knowledge proof by which user can prove to the authentication server that he has the password without having to send the password to the server either clear text or in encrypted format. This is a protocol in which the data learned by one party (i.e., The inspector) allow him/her to verify that a statement is true but does not reveal any additional information. In this paper we first discuss about zero-knowledge protocol proof system of knowledge and also key exchange between users and which then is modified into an authentication scheme with secret key exchange for confidentiality. The whole protocol involves mutual identification of two users, exchange of a random common secret key or session key for the verification of public keys.
