摘　　要：针对现有的RFID(Radio Frequency Identification)认证协议存在的安全隐私保护弱点以及成本过高问题,提出一个基于PUF(Physical Unclonable Functions)的轻量级RFID安全认证协议。利用PUF与LFSR(Linear Feedback Shift Register)实现阅读器和标签之间强的安全认证。另外,协议中增加了阅读器二次验证安全机制,为了保证阅读器与标签共享密钥同步,添加了不良攻击标识M等手段,解决了已有认证协议存在的多种安全漏洞。安全性分析表明该认证协议不仅成本低,而且能够有效地抵抗物理攻击、DoS攻击、同步破坏攻击等多种攻击,满足了认证协议的正确性、安全性、隐私性。In order to solve the weakness in security and privacy and the problem of high-cost which the existing RFID authentication protocol has,we propose a PUF-based lightweight RFID secure authentication protocol.We use PUF and LFSR to realise strong security authentication between reader and tag.In addition,in protocol there increases the dual-authentication security mechanism for reader,and in order to ensure the key synchronisation sharing between the reader and the tag,the malicious attacks flag M is also added,which solve a series of security vulnerabilities in existing RFID authentication protocols.Security analysis shows that this protocol is low-cost,and can also resist physical attack,Do S attack,desynchronisation attack and other attacks efficiently.Moreover,it meets the correctness,security and privacy of the authentication protocol.
