摘　　要：针对于传统密码锁安全性能低及可靠性差等问题,立足于芯片中数据存储的保密性,运用EDA技术自顶向下的设计方法,提出了基于FPGA的四位电子密码锁的设计与实现方法,所设计的四位电子密码锁具有解锁、密码修改、报警提示及液晶显示功能。设计分析与仿真结果表明,基于FPGA所设计的四位电子密码锁保密性更高、灵活性更好,使得数据存储的整体可靠性增强,为提高数据的保密性提供了新的解决方案。Traditional lock faces safety problem of low performance and poor reliability. Based on the data stored in the chip of confidentiality, and using EDA technology top-down design approach,we proposed the design and implementation of a 4-bit FPGA-based electronic lock ,which provides unlock, password change ,alarm and LCD functions.Design analysis and simulation results show that the designed FPGA-based electronic lock provides better confidentiality, flexibility and reliability for data storage.This approach provides a novel solution for improving data confidentiality.
