一种基于键盘中断反过滤的密码保护方法

摘要

在日常的计算机应用中不可避免的要经常输入帐号和密码,但这些隐私信息却常常被不法分子拦截,从事非法活动,给用户带来重大损失.该文提出一种基于键盘中断反过滤的密码保护方法,采取修改中断IDT表的函数地址或者修改IOAPIC重定位表的中断定位来抢先拦截,获取键盘信息,避免被不法分子截获,从而保障隐私信息的安全.%The inevitable everyday computer application often needs to enter the account number and password, but these priva?cy information is often illegal interception, engaged in illegal activities, bring great loss to the user. This paper proposes a pass?word protection method based on inverse filtering the keyboard interrupt, to amend the interrupt IDT table function address or modify the IOAPIC relocation table interrupt positioning to forestall to intercept, keyboard access to information, to avoid illegal interception, in order to protect the privacy of information security.
