一种增强型RFID双向认证协议

An Enhanced Mutual Authentication Protocol for RFID

RFID系统的安全性问题一直是研究者们关注的热门话题。针对RFID认证协议,研究者们提出的方案各有千秋,比如基于Hash函数的方法易实现,基于密钥的方法更安全。论文对一种基于非对称密钥和Hash函数的RFID认证协议进行了分析与改进。改进后的协议安全性更高,能够抵抗多种非法攻击,更有实用价值。最后,文章用BAN逻辑分析方法形式化验证了改进协议的安全性。

The security of RFID system has always been a hot topic for researchers.For the RFID authentication protocol,the solutions proposed by the researchers have their own advantages.For example,the method based on Hash function is easy to imple ment,and the key-based method is more secure.This paper analyzes and improves an RFID authentication protocol based on asym metric keys and Hash function.And the improved protocol has high security and practicability with resisting many kings of attacks.Finally,the article formal analyzes the security of improved protocol by using BAN logic.
