| 摘 要： | 为了提高低成本的RFID系统的安全性,利用混沌系统产生的混沌序列对RFID系统中阅读器与标签之间传输的数据进行了加密。混沌序列的产生,采用了基于m-序列的参数变量可变的Logistic映射。另外,为了提高混沌序列的周期,用m-序列对由Logistic映射产生的序列进行扰动。加解密采用同样的机制,可以很好地实现数据的加解密,从而可以降低RFID系统的成本。进而建立了一个基于混沌加密技术的RFID系统安全模型,并对其工作流程及读写控制机制进行了分析。

| Abstract: | In order to improve the security of low-cost RFID system,the chaotic sequence which is generated by chaotic system is used to encrypt the transmission data between the reader and tag of RFID system.Chaotic sequence is generated by the use of m-sequences based on the parameters of the Logistic mapping variable.In addition,the sequence which is generated by logistic mapping is perturbed to increase its period.Encryption and decryption use the same mechanism to achieve a very good encryption and decryption of ... |
