چکیده
The electromagnetic waves emitted by computer system at work, and may cause information leakage, will be a serious threat to information security. This paper first analyzed the mechanism of the electromagnetic information leakage based on electromagnetics and antenna theory, for the process of resulting in electromagnetic information leakage, "anti-radiation leakage”,” preventing electromagnetic interception", "preventing electromagnetic emersion” is put forward. Finally, concrete implementation means of the three layers of protection model of computer electromagnetic information leakage is discussed in detail from two aspects of hardware and software protection.
