摘要
随着网络的快速发展,用户个人隐私安全性需求日益增强,木马是威胁个人隐私安全的重要手段。对于键盘记录型木马,安全密码框的防范性能是较高的,但是有一些技术仍能突破其防御。研究安全密码框的改进技术,并实现了一种基于过滤驱动的安全密码框,采用应用与驱动同步、直接访问键盘控制器模拟按键等技术,以干扰驱动级的键盘记录木马。测试结果表明,该软件比普通的安全密码框有较高的防御键盘记录能力。
With the rapid development of network, users' privacy security requirement keeps increasing, and Trojan is one of the important means threat to privacy. Secure password input performs well for prevention the Trojan of keyloggers, but some technologys are still able to break through the defense. This paper researches and implements a secure password input based on filter driver. Adopted techniques conclude establishing synchronization between application and driver, directly accessing to the keyboard controller and simulating the key stroke,to interfere with the driver stage keylogger. Test results show that the software performs better than the general security password input in defensing keylogger.
