Problems solved by technology

[0015] For wireless LAN detection, there are currently two modes: active scanning and passive scanning. Both schemes can realize the detection of wireless LAN access points, but ordinary wireless devices cannot use these two modes at the same time to realize real-time wireless LAN detection. , resulting in a decrease in detection efficiency and a delay in detection time

Embodiment Construction

[0078] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0079] The system architecture diagram of the present invention is as follows figure 1 As shown, the whole system is logically divided into three major components: hardware platform, software platform, and application platform. At the same time, each part is divided into different functional modules according to their different task requirements and realization functions, thus forming a logically independent platform. But the tightly coupled system structure in the implementation. The advantages of this design are: firstly, the maintainability of the system is guaranteed. Since the hardware, software and application software are all based on modular design, after the whole system fails, only the corresponding modules need to be replaced to ensure the normal operation of the whole equipment. At the same time, the software is based on the modular de...

Abstract

The invention discloses a portable wireless network detection evidence-obtaining system which comprises an embedded hardware platform, as well as an embedded operating system module and an application platform module based on the embedded hardware platform, wherein the embedded hardware platform comprises an embedded mainboard and a wireless network card module; the wireless network card module specifically comprises a network interface controller, a baseband processor, a medium frequency processing unit, a radio frequency processing unit, a transmitting-receiving module and an antenna sequentially connected. According to the invention, a system framework taking a modularization architecture as a main body, the hardware platform based on a low-power and high-performance arm embedded platform, and a software platform taking a customized safe embedded Linux operating system as a backbone are realized, and the technologies such as wireless network drive optimization, concurrence multithreading real-time monitoring and multimode wireless security detection are combined and adopted, so that the problems about miniaturization, mobility and low energy consumption of equipment are effectively solved, and the perfect wireless detection function is realized through multiple innovative technologies.

Description

technical field [0001] The invention discloses a portable wireless network detection and evidence collection system, which relates to the technical field of wireless communication. Background technique [0002] With the development of network communication technology, the development and application of wireless networks are becoming more and more popular. In real life, people can come into contact with various wireless network communications everywhere around them. Correspondingly, the security of wireless network communication is getting more and more attention. In order to ensure the security of network communication, it is essential to involve a network monitoring system. Compared with traditional Ethernet, wireless network has differences as well as similarities. The signal transmission of the wireless local area network is completely broadcast and transmitted by radio, which means that everyone can receive and crack the wireless signal with a certain device, so the wi...
