一种基于二维条码的移动商务一次性口令认证方案

A New OTP Authentication Scheme for M-Commerce Based on 2-D Bar Code

本文在现有身份认证技术的基础上,结合二维条码和一次性口令认证技术,提出了移动商务环境下的一种身份认证方案。与传统方案相比,该方案考虑了移动商务的安全性要求及移动设备的技术限制,安全性高,运算量小,实现了通信双方的相互认证,并且利用二维条码技术增强了认证方案的安全性和服务的便捷性。

The paper proposes a new OTP authentication scheme based on 2-D bar code and adapts it into M-commerce environment. Compared to the traditional schemes,the scheme considers the strains of wireless networks and mobile equipment. The scheme not only isolates such problems of traditional schemes, but also provides mutual authentication between the user and the server,and the security is strengthened by 2-D bar code.
