Abstract

The invention discloses an electromagnetic signal red-black identification device and identification method for a wireless network. The electromagnetic signal red-black identification device comprisesan antenna, a receiver, a signal acquisition and processing unit, a calculation and analysis unit, a power supply module and a clock module, wherein the receiver receives wireless electromagnetic signals through the antenna, processes the signals and then sends the signals to the signal collecting and processing unit; the signal acquisition and processing unit completes acquisition and processingof signals and outputs the signals to the calculation and analysis unit; and the calculation and analysis unit is used for identifying the wireless electromagnetic red and black signals by utilizinga convolutional neural network technology of artificial intelligence deep learning. The identification method is based on the electromagnetic signal red-black identification device. According to the electromagnetic signal red and black identification device and method for the wireless network, the problem that the electromagnetic signal red and black features are weak in difference and not easy toextract in the actual environment is solved, and the bottleneck that the red and black signal features are difficult to extract manually is broken through.

Description

technical field [0001] The invention relates to an electromagnetic signal red and black identification device and identification method for a wireless network. Background technique [0002] With the development of information technology, wireless networks have covered all aspects of people's work and life, and network security issues have attracted more and more attention. Due to the openness of wireless communication networks, radio waves are easily intercepted, analyzed or deciphered. Encryption algorithms are usually used to encrypt and protect the information transmitted in the wireless network. This encrypted signal is a black signal, which is difficult to decipher after being intercepted; the unencrypted signal is a red signal. If the information is sent without encryption (information is sent out), the electromagnetic transmission signal is intercepted or deciphered, which will cause the leakage of the "red signal". Therefore, it is necessary to identify the "red" a...

Problems solved by technology

The demodulation and decoding methods of this known communication protocol can only be aimed at a single device, and other network devices that cannot be popularized have poor versatility; there are many models of wireless network terminals, inconsistent communication systems, and various modulation modes. In the case of an unknown wireless communication protocol, it is difficult to demodulate, decode, and restore wireless electromagnetic signals into bit stream data
