Multi-User WPA Threadpool And Data En(De)cryption Of A Wi-Fi Tester

WLAN(Wireless Local Area- Network, WLAN) technology is a combination of computer network and wireless communication, it is fast,efficient and flexible.How to apply this technology to the enterprise application, and ensure multi-user access,data transmission and data transmission security at the same time, it will be one of the technical problem should be solved urgently in the next few years.This paper is based on a Linux Wi-Fi tester project,based on the PCIe interface Atheros 9380 wireless network card and Linux server hardware architecture,accroding to the design method of Linux network equipment driving.Firstly,we need a requirement analysys of the system.Then,using Linux open source code,wireless network driver source code(Compat-wireless)as the basis for cutting and modification,change a network card into multiple network cards by virtual technology,simulate multi-user online and offline process to a AP,support Open/WEP/WPA/WPA2 encryption and authentication methods,to test the enterprise AP.This paper major in describing design ieda and implementation scheme of multi-user threadpool and data en(de)cryption.Tester simulates one enterprise AP with multiple STA accessing, ensures the perfect performance test of AP at the same time, and saves more manpower cost and material cost than other methods.
