基于单片机的蓝牙加密密码锁的设计

Design of Bluetooth Encryption Cipher Lock Based on SCM

针对电子密码锁安全性及易用性差等问题,设计了一种以STC89C52单片机为核心,通过HC-06蓝牙模块与安卓手机连接,实现随机密码加密的密码锁。利用单片机自身的EEPROM存储数据,通过E0加密算法对数据进行保护,实现了手机对密码锁的控制。实验表明,蓝牙加密密码锁可以实现随机密码功能,具有安全性高、使用方便、价格低廉等特点。

Aiming at the problem of low security and poor usability of electronic password lock at present,this article designs a kind of cryptographic lock which is encrypted by random password through the connection of HC-06 Bluetooth module and Android mobile phone,which is based on STC89C52 single chip.The data is protected by the EEPROM stored in the microcontroller itself,and the data is protected by the E0 encryption algorithm.The mobile phone controls the encryption lock of Bluetooth.The experiment shows that the cipher lock can realize the function of random cipher.It has the characteristics of high safety,stable performance low price.
