摘　　要：基于KEELOQ技术的解码运算,采用滚动码技术,选用加密芯片HCS301进行跳码编码并对其进行解码,同时采用单片机PIC16F689进行了远程无钥匙进入RKE系统设计。通过对KEELOQ加密技术的分析,提出了一种基于单片机控制的软件解码方案,给出了系统密钥的产生和解码的过程。该系统具有保密性高、使用方便、成本低的特点。通过对系统样机的功能测试和信号分析验证了解码方案的有效性及系统的功能性。KEELOQ code hopping technology is a nonlinear anti-encryption algorithm designed for secure Remote Keyless Entry（ RKE） systems. It combines a 66-bits transmission length so as to prevent the system from code predicting,code grabbing and code scanning. Because of its feature of high-security,it effectively overcomes the disadvantages of the traditional fixed code technology. This paper researches on the hopping code encryption algorithm and presents the decode method based on KEELOQ encoding technology,which is realized by programming in the microcontroller PIC16F689. The experimental results show that the design achieves the anticipative effects.
