Abstract

The invention discloses power line information secret stealing prevention equipment, and specifically relates to the technical field of power line carrier attack interception. The power line information secret stealing prevention equipment includes a shell, a main control circuit board is fixedly mounted on one side of the interior of the shell; a noise interference source and a PWM (Pulse-Width Modulation) wave pulse modulation data interference unit are fixedly mounted on one side, close to the main control circuit board, of the bottom of the inner cavity of the shell; a high-pass filter isfixedly installed on the side, away from the main control circuit board, of the bottom of an inner cavity of the shell, and a first power filter and a second power filter are arranged on the two sidesof the high-pass filter respectively. According to the invention, the high-pass filter is used for carrying out communication in a radio frequency signal mode or a radio frequency signal radiation mode or a coupling mode through a power line mode, thereby preventing information from leaking radio frequency signals which can be externally hung or accessed by other equipment, suppressing the radiofrequency signals, guaranteeing the normal use of a power supply, and guaranteeing the use safety of the device.

Description

technical field [0001] The invention relates to the technical field of power line carrier attack interception, and more specifically, the invention relates to a power line information anti-theft device. Background technique [0002] The power line is the most common physical medium with the widest coverage. The power line network formed by it is a nearly natural physical network. The power line is used as the carrier signal carrier and is the only wired communication method that does not require line investment. As a communication As an emerging application field of technology, power carrier communication technology has attracted the attention of the world for its attractive prospects and potential markets. [0003] However, the existing technology has the following shortcomings: the power line is likely to be used as a channel for stealing and leaking secrets, or even a channel for the enemy to destroy data on our key infrastructure information equipment, posing a serious t...
