Abstract

The invention provides an interference signal generator, a shell and a shell. The interference signal generator is used for protecting a power utilization module and comprises a random number generation unit and a first unit connected with the random number generation unit, wherein the frequency of the electromagnetic waves generated by the first unit is the same as that of the electromagnetic waves generated by the power utilization module, and the random number generation unit carries out amplitude modulation on the electromagnetic waves generated by the first unit. According to the interference signal generator, a random number generation unit is adopted to carry out amplitude modulation on output of a power supply unit; the output subjected to amplitude modulation enters a first unit,so that the first unit generates interference electromagnetic waves with random amplitudes, and the frequency band of the interference electromagnetic waves generated by the first unit is the same asthat of working condition electromagnetic waves generated by the power utilization module during working, so that the two kinds of electromagnetic waves are superposed and then are radiated to the environment, an attacker is difficult to distinguish the interference electromagnetic waves from the working condition electromagnetic waves, and the information safety is protected.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an interference signal generator, a casing and a casing. Background technique [0002] When the computer system is working, electromagnetic leakage of information occurs in the display screen, hard disk, keyboard, etc. of the system. The leakage method is line conduction emission and space radiation. The leakage intensity depends on the circuit design, structural design and working characteristics of the system. [0003] Research at home and abroad has shown that the electromagnetic leakage signal of the computer can be captured by receiving equipment (receiver, spectrum analyzer, etc.), and the operating information of the computer can be restored by post-data processing methods. The problem of computer electromagnetic radiation leaks has attracted great attention from various countries. To prevent these information from being transmitted in the air, special technic...
