软硬件协同的安全录入系统开发

Safety Type-in System Based on Hardware and Software Co-design

键盘录入信息的保护大多采用安全软件的方式,无法防止按键信息在录入至计算机途中被硬件记录器非法窃取,且硬件记录器无法被安全软件查杀。本文结合USB驱动技术设计一种可加密防侧录的USB键盘录入系统,通过可加密的USB键盘配合计算机端USB驱动解密的方式,提高按键信息的安全性。测试结果表明,该系统可有效保护按键信息在传输过程中的安全。

Security software is mostly used for protection of the keyboard input information. It cannot prevent the key information in the entry way to the computer being illegally stolen by keylogger, and the keylogger cannot be killed by security software. An encrypted an- ti-keylogger USB keyboard entry system is designed combined with USB drive technology, through encrypted USB keyboard with the computer end of the USB drive decryption. The design improves the security of key information. Test results show that the system can effectively protect the security of the key information in transmission process.
