基于混沌混合序列的RFID系统流加密方案

Stream Cipher Scheme for RFID System Based on Chaos Mixed Sequence

在分析了RFID系统所面临的数据安全问题及现有解决方法的基础上，将一种流加密方案用于解决RFID数据安全问题，将m序列和Logistic混沌序列相结合生成一种混沌混合序列，理论分析和计算机仿真结果表明，该混合序列具有良好的随机性、自相关性等许多优良特性，且具有较理想的线性复杂度，适宜作为流加密系统的密钥序列。

This paper analyzes the data security problem of RFID system and the current resolvents. A stream cipher scheme is used for solving the RFID data security problem. A chaos mixed sequence is created by combining m-sequence and chaos sequence. The theoretic analysis and the computer simulation show that the mixed sequence have many excellent characteristics and can be as code key of stream cipher suitably.
