A System For Authentication And Audit Of A Cloud WiFi Device

This topic is put forward, based on a demand as follows: small and medium-sized businesses only to install a device, the device can connect to cloud platforms provide unified management services, become a cloud WiFi(Wireless Fidelity, Wireless local area network) based on IEEE 802.11 b standard equipment, and users get Internet access in the facilities, don’t need to be very troublesome certification process, do not need to install the special application software, but need to be forced through a browser for simple authentication.And expressly prescribed by the ministry of public security of the existing network security, the need to provide user behavior of audit on the Internet.The demand for the above, the author puts forward in a cloud of WiFi devices realize authentication and audit system.You first need to choose a suitable hardware chip, to support a WLAN basis function of AP(Access Point, commonly known as wireless Access Access Point) equipment.This design chose the Atheros AR9341 chip company, it has 533 MHZ frequency, support 802.11 n technology, is the comparison of the wireless network technology development to the present outstanding a chip.Run on the chip is embedded Linux system, the operating system as part of the open source software, for cutting and kernel configuration, can according to need.And then, on the design of the software system, the use of open source wifidog agreement for architecture prototype, interaction protocol defines a cloud platform, the construction of the complete cloud WiFi;Use a firewall technology, and audit completed a certification and audit system.WiFi authentication technology has a lot of kinds, such as PPPo E, 802.1 x and portal authentication, this subject is to study and implement the portal authentication.Audit system is designed to meet the requirements of the ministry of public security for network security, is for users to get to the Internet via libpcap packet, the packet is analyzed after the user’s online behavior records, and report through interaction with cloud platform agreement to log management server.The final results will be a certification and audit system cloud WiFi devices, it can be automatically connected to a cloud platform management equipment, users don’t need to install the client application, after connect WiFi by merchants to customize a web page to complete the online certification, but has the provisions on the Internet security protection measures according to the ministry of public security audit required by the function.
