射频识别系统抗碰撞可信协议研究

Research of Credible Protocol with Anti-collision for RFID System

RFID在得到广泛应用的同时,安全性的隐患也接踵而来.当多个标签同时进入感应区范围时,标签的合法身份要首先进行验证.本研究在现有的RFID认证协议的基础上,结合单向散列函数提出了一种采用带敏感密钥的用户、阅读器与服务器三者双向认证协议,可抵抗外界的重放攻击、伪造攻击及生日攻击等,并结合优良的标签二进制序列的列队算法快捷和安全地识别出合法身份的用户.本方案算法简单实用,可应用于现实的识别系统之中.

With the development of RFID,hidden danger in its safety is appearing.When several labels enter the induced zone range at the same time,the legal identity of label wants to carry on a verification first.With the foundation protocol of RFID,the double protocol adopting a consumer tape sensitive key and reader and server three can resist playback attack,forgery attack and birthday attack etc,and may combine the algorithm of good label binary array to identify a consumer of legal identity fast and safely.This scheme algorithm is simple and practical,which can be applied to the real identification systems.
