Abstract

The invention discloses an active protection system for electromagnetic radiation information leakage in high-frequency data transmission, relates to the field of computer information security, and aims to solve the problem that an existing electromagnetic radiation information leakage protection system cannot determine whether information leakage exists or not. A radio frequency transceiving system is used for receiving an electromagnetic radiation signal and sending the electromagnetic radiation signal to a control system, and is also used for transmitting a random noise signal and a bait information signal; the control system is used for controlling the random noise signal and the bait information signal transmitted by the radio frequency transceiving system according to the received electromagnetic radiation signal; and an early warning server is used for giving an alarm when an attacker uses bait information. The system is suitable for actively protecting the electromagnetic radiation information leakage.

Description

technical field [0001] The invention relates to the field of computer information security. Background technique [0002] In the process of high-speed data communication, because the electromagnetic radiation transmitted by the data transmission line has transmission signals that can be re-received, amplified, and decoded, and the original transmission data can be restored from the decoding results, which seriously affects the security of data transmission. Therefore, there are many solutions to ensure transmission safety by shielding the radiation signal propagation path. E.g. The application number is 200610146229.1, and the name of the invention is a low-emission safe and confidential computer. The computer achieves the electromagnetic radiation shielding performance of the specified index by using shielding technology, filtering technology, and electromagnetic compatibility technology, and realizes the shielding of the transmission path of electromagnetic radiation. ...
