Dynamic Encryption Lock Used for Matching Random Signals by Algorithm Program

Abstract:

This project aimed to make a research on code lock containing algorithm and dynamic random code based on the existing intelligent lock. This code lock can control the door lock through software program, which was to draw random digit into MD5 program of single chip microcomputer, allow the same data being processed by MD5 encryption program to present different results, such that, the encryption program can keep dynamics, so the MD5 encryption program being amended by pseudo-random number existed separately in key and lock, then this program would be the identity card for key to open the door and only the program of key was identical with that of the lock can the door open, which largely improved the safety.
