一种智能攻击模型在RFID防伪协议中的研究

摘要

本文研究一种RFID防伪技术和系统,首先给出了一种基于RFID技术的防伪系统软硬件系统架构,进而分析了该防伪系统的层次结构,然后针对系统中防伪安全协议的复杂性提出了智能伪造攻击模型,利用A~*搜索算法进行路径搜索得到最小攻击代价树,作为对本文提出的防伪系统,尤其是系统中采用的防伪协议的评价.最后在VC++和Matlab环境下对本文提出的模型进行了实验验证,实验结果表明攻击模型对RFID防伪协议的验证以及分析是有效的,从而为RFID技术与防伪技术的结合提供了一个全新的参考.%A RFID technology and anti-counterfeiting system was studied in this paper. Firstly, we propose a hardware and software framework of anti-counterfeit system based on RFID technologies; furthermore the hierarchical structure of the anti-counterfeit system was analyzed in details. Then aimed at the complexity of the anti-counterfeit system an intelligent attacking model was presented here, and the A~* algorithm is adopted in this attack model and used to search a lowest price tree by the fictional attacker in order to evaluate the proposed anti-counterfeit system especially for the protocol used in this system. Finally, an experimental testing with VC++ and Matlab was simulated. Simulation results indicate that the proposed modeling methods can be used effectively to model complex anti-counterfeiting systems.
