Abstract: Aiming at secure problem of low communication security and easy to be attacked between reader/writer and labels for existed RFID system, a dynamic real-time key method based on Logistic chaotic sequence is introduced, and a RFID secure encryption mechanism based on chaotic sequence is proposed, which uses dynamic real-time key to encrypt the communication messeges between reader/writer and electronic labels. Simulation experimental results show this method can solve the problems of illegal access, tags forgery, data betray, and position tracking in RFID system.

摘要： 针对现有RFID系统读写器和标签之间通信安全性低、易受到各种攻击的安全问题，介绍基于Logistic混沌序列的动态实时密钥方法，提出一种基于混沌序列RFID的安全加密机制，采用动态实时密钥对RFID系统中的读写器与电子标签通信消息进行加密。仿真实验结果表明，该方法能够解决RFID系统中非法存取、伪造哄骗、数据泄露、位置跟踪等安全问题。
