摘　　要：针对现有RFID认证协议在安全认证过程中,由于协议的设计缺陷,导致协议安全性不足的问题,提出了一种利用同步化随机数以及PUF改进的轻量级RFID认证协议。首先提出了一种对RFID协议的去同步化攻击方法,并分析其原因;然后通过在标签和读写器两端设置一个同步化随机数,增强协议抗去同步化攻击的能力;最后,在标签中引入了PUF,通过PUF的不可克隆性提高了标签密钥的抗攻击能力。分析结果表明,新协议能有效地抵抗多种攻击,在保证一定效率和开销的同时具有更高的安全性。In view of the existing RFID authentication protocol is insufficient in the security authentication process due to the flaws in the design of the protocol,this paper proposed an improved lightweight RFID authentication protocol using synchronized random number and PUF.It firstly proposed a desynchronizing attack method on RFID protocols,and analyzed the reason.Then it enhanced the protocol’s ability to resist desynchronization attacks by setting a synchronized random number at both ends of the tag and reader.Finally,it introduced the PUF in the tag,used the PUF’s non-clonality to improve the tag’s anti-attack capability.The analysis results show that the new protocol can effectively resist multiple attacks,and it has higher security while ensuring certain efficiency and overhead.
