基于PUF的轻量级RFID安全认证协议

Lightweight RFID Security Authentication Protocol based on PUF

为解决射频识别系统易受传统攻击和物理克隆攻击等问题,提出一种基于物理不可克隆函数的轻量级射频识别安全认证协议。采用随机数、轻量级杂凑函数、轻量级分组算法和基于物理不可克隆函数等密码原语来实现通信安全。协议可防范窃听、篡改、假冒、重放和物理克隆等多种攻击方式,可有效降低计算处理和存储资源消耗,比较适合于低成本、低功耗且硬件资源受限的射频识别系统。

In order to deal with the problem that RFID system is vulnerable to traditional attacks and physical clone attacks,a lightweight RFID security authentication protocol based on PUF(physical unclonable function)is proposed.It uses random numbers,lightweight hash functions,lightweight grouping algorithms and cryptographic primitives such as PUF to achieve communication security.This protocol can prevent eavesdropping,tampering,counterfeiting,replay,physical cloning and other attacks,and can also effectively reduce the consumption of computational processing and storage resources.It is more suitable for low-cost,low power consumption and constrained hardware resources RFID systems.
