【摘 要】在科学技术日新月异的今天，键盘作为计算机输入输出系统中不可缺少的组
成部分被广泛应用。无线键盘经常用于传输用户各种类型的个人信息。这些个人信息如
果让不怀好意的人所截获，就有可能会带来很大的精神损失或者财物损失。无线键盘与
计算机主机进行信息通信时，必然会或多或少产生辐射，攻击者就会对辐射出来的信息
进行采集，捕获辐射出来的信息，导致计算机能够被攻击者利用的信息的泄漏。在本文
中，使用来接收信号，信号处理和显示的仪器是一个频谱分析仪，它是用来测试在无线
键盘操作过程中产生的辐射信号。最后对所采集到的频谱数据进行了比较分析，提出了
解决无线键盘电磁信息安全问题的一些方法和措施。

【Abstract】Nowadays，with the development of the scientific technology,keyboard has been
widely used as an important part of computer input and output system. Wireless keyboard is
often used to transfer many types of user’s personal information.If these information is
intercepted by others ， it’ll cause a huge damage of spirit or property. when the wireless
keyboard is changing information to computer case.Then the attacker will collect and obtain
the information of radiation signal ， which can cause the leakage of computer useful
information. In this paper, the instrument is used to receive signals, signal processing and
display is a spectrum analyzer, which is used to test the radiation signal generated during the
operation of the wireless keyboard. Finally, the collected data are compared and analyzed, and
some countermeasures and measures are put forward to solve the problem of wireless
keyboard information security.
【 Keywords 】 Wireless keyboard Electromagnetic radiation information information
