一种基于 PUF 的低成本 RFID 认证协议分析与改进

分析了一种基于物理不可复制（PUF） RFID认证协议的安全性，通过中间人篡改协议通信内容，指出该协议容易遭受去同步攻击和整体揭露攻击，给出了攻击的细节，并将原有协议进行改进。对比分析表明：改进的协议成本低，安全性高，具有极强的隐私性，并可有效的避免上述攻击问题。

The Analysis and Improvement of A RFID Authentication Protocol Based on Physically Unclonale Function

T he paper analyzed the security of a Radio Frequency Identification （ RFID ） authentication protocol based on Physically Unclonale Function （PUF ） and found it cannot resist de‐synchronization attack ,full disclosure attack by man‐in‐the‐middle attack .The paper described the details of these attacks and improved the protocol .The improved protocol can effectively avoid these attacks .Analysis of security and performance shows that the improved protocol can provide strong security and privacy with low cost .
