基于PIC16F886单片机的KEELOQ防盗系统设计

摘要

To solve the problems of car security, the paper proposed a security system based on KEELOQ algorithm. KEELOQ hopping encoding algorithm is a high-security technology, which includes encryption and decryption algorithm. It is suitable for remote control and command recognition applications, and it is patented to Microchip crops. Based on KEELOQ algorithm, the security system was designed for car door locks. Using hardware encoder HCS300 and MCU PIC16F886 for soft decoding, experiment application results showed that the anti-theft system was working reliably and had good promotional value.%为解决轿车安全防盗问题,提出了基于KEELOQ算法的防盗系统设计.KEELOQ滚动编码加密算法是Microchip公司提出的一种高保密安防技术,内含加密和解密算法,其适用于遥控和命令识别等应用场合.采用KEELOQ加密技术,设计了汽车门锁防盗系统并对其进行了研究,利用HCS300实现了硬件加密和微处理器PIC16F886实现了软件解密.实验结果表明,系统运行可靠,有较好的推广价值.
