基于DES的滚动加密算法在机车防盗系统中的单片机实现

A Hopping Encoding Algorithm Implemented in the Single-Chip Processor of a Motor-Vehicle-Monitoring System

本文分析了 DES算法的特点及安全性 ,并在此基础上提出了一种滚动加密算法 ,使得在信道上每次传输的代码是唯一的 ,从而防止被扫描跟踪。

This paper makes an analysis on the characteristics and security features of the DES algorithm and then proposes a hopping encoding encrypting algorithm based on it. With hopping encoding, the DES algorithm ensures uniqueness of code transferred each time in the wireless channel. Its application in a Motor-Vehicle-Monitoring System is also illustrated.
