摘　　要：为降低密码锁的成本,研究与设计了一种基于8051单片机的密码锁加密模块。该模块运用随机矩阵进行加密,并结合高性能单片机,辅以四输入与非门模块,不涉及外围接口芯片,从而减小了PCB面积。分别分析了模块的功能设计和模块的结构设计,并对硬件电路、代码部分进行了仿真测试。软件仿真测试结果表明,与传统方法相比,该方法加密更快速、可靠性更高、成本更低。In order to reduce the cost of cryptogram lock,the encryption module for the lock based on 8051 single chip computer is researched and designed.The module implements encryption by adopting random matrix,and combines the high performance single chip computer aided by four-input NAND gate module,the peripheral interface chip is not invloved,thus the area of PCB is decreased.The functions and the structral design of the module are analyzed respectively,and the hardware circuitry and the coding section are tested by simulation.The result of software simulation indicates that comparing with traditional method,this method features faster encryption,higher reliability and lower cost.
