摘要
目前,无线射频识别技术被广泛地应用到很多领域,但随着RFID标签应用到单品级消费品中,RFID系统突显出一些安全与隐私问题。主要针对Logistic映射进行改进,将它作为加密算法的轮密钥发生器,并在DES算法的基础上提出一种简化算法,并利用MATLAB进行仿真实验。验证提出的简化算法在理论上具备一定的安全性和抗破译性,更适合RFID应用系统。
At present, Radio Frequency Identification technology has been widely applied to many fields, but with the electronic tags applied to a single grade in consumer products, the system of RFID highlights a number of the security and privacy issues. Focuses on the Logistic map and tries to improve it as a chaos sequence generator. Proposes a simplified algorithm based on DES algorithm and carries out the simulation with MATLAB software to further verify that the simplified DES algorithm has a certain security and anti-attack in theory. It is more suitable for RFID application systems.
