基于成绩管理系统中ECC一次性口令的身份认证方案

A Scheme of ECC One-Time Password Identity Authentication in the Score Management System

本文阐述了椭圆曲线密码体制的基本原理及其优点,介绍了一次性口令认证技术的原理,分析了S/Key一次性口令系统。利用ECC密码体制对现有的一次口令系统进行改进,实现了成绩管理系统中双向认证的一次性口令认证方案,在运算速度和存储空间方面相对其它身份认证方案有较大的优势。

This paper illustrates the basic principles and advantages of the Elliptic Curve Cryptosystem （ECC）, intro- duced the principle of One-time password authentication technology, and analyzed S/Key One-time password systems. Based on the ECC password system, the current one-time password system is improved, and the Scheme of ECC One-Time Password for the Two-way Identity Anthentieation is realized in the Score Management, which is eompara- tively superior to others in calculating speed and storage space.
