一种改进的基于Hash函数的RFID双向认证协议

An Improved RFID Mutual Authentication Protocol Based on Hash Function

针对物联网应用中,基于Hash函数的Radio Frequency Identification(RFID,射频识别)安全认证协议存在缺陷以及安全协议认证效率不高等问题,提出了一种改进的基于Hash函数的RFID双向安全认证协议,协议能保护标签的数据隐私,防止重放、追踪、伪造等攻击.通过和已有的此类安全认证协议进行安全性分析和性能比较,结果表明该协议具有更高的认证效率,并且引入了标签认证标志Tuse、Tstore以及动态秘密值S,能有效地防止去同步化攻击的威胁,适用于低成本的RFID系统.

In view of the existing defects of RFID authentication protocol , based on the Hash function , and the low efficiency of the security protocol authentication in the application of the Internet of Things , it proposed an improved RFID security mutual authentication protocol , based on the Hash function .This protocol can protect data privacy , and prevent replay attack , privacy track , and spoofing attack .Com-pared with other protocols of this kind in security and performance , this protocol, which uses Label certi-fication mark Tuse , Tstore and dynamic secret value S , can prevent desynchronization attack , has higher efficiency , and is suitable for low-cost RFID systems .
