基于Hash函数的RFID改进协议及其仿真

摘要

针对现有的Hash链协议存在的安全隐患和效率的问题,提出了一个基于Hash函数的RFID改进认证协议,经过分析该协议可以有效解决重传攻击、跟踪、假冒攻击、前向安全性等安全问题,同时采用Verilog HDL硬件编程语言,对读写器和标签之间的信号流进行仿真.由于在改进协议中仅使用了Hash函数,所以文中提出的改进协议更适合于低成本的RFID系统.%Due to the security and efficiency of existed Hash-chain, an improved RFID authentication protocol based on Hash has been proposed, which can effectively solve fake attack,'attack, tracking and prior security. The verilog hardware programming language is used to simulate the signal flow changes of wireless transmission channel. Because of the use of Hash function, the improved protocol is more suitable for low cost RFID system.
