基于位替换运算的RFID双向认证协议

Bits Substitution Based on RFID Mutual Authentication Protocol

安全性是射频识别系统面临的重要隐患,针对该问题,设计了用于加密的位替换运算,并提出了一种新的基于位替换运算的RFID双向认证协议(SRMAP)。安全与性能分析表明:SRMAP可抵抗多种潜在攻击,且能够使标签内计算操作、存储空间及通信量得以降低。最后,采用BAN逻辑方法形式化证明了该协议的正确性与安全性。

According to the problem that security is an important hidden trouble of RFID system,the bits substitution operation for encryption is designed,and a new bits substitution based on RFID mutual authentication protocol （SRMAP） is proposed.Security and performance analysis show SRMAP can resist various attacks and make tags use fewer computation operation,storage space and communication cost.Finally,it proves formally the protocol is correct and secure with BAN logic.
