| With the continuous development of wireless communication technology, wireless LANs has been more widely used, and has become an important part of a computer network.However, because of the special nature of transmission media, wireless transmission medium is shared. So with respect to wired networks, wireless local area network to send and receive data more vulnerable to eavesdropping, Wireless LAN security issues become an obstacle to hinder its development.This paper is the analysis of security issues that exist at the present stage of the wireless LAN as a starting point, The realization of the wireless LAN security is the main object of study of this thesis. Research is mainly based on IPsec(Internet Protocol Security) protocol suite on its end to end secure data transmission technology transfer were innovative and exploratory, Its content is mainly manifested in the following aspects:1. Detailed study of the status of wireless LAN development and current problems, the international situation and prospects, and our wireless network in the field of development.......2.Detailed study of network protocols used by wireless LAN principles and protocols algorithms defects and safety problems that may result from these defects......3.IPSec protocol suite study co-related technology, a detailed study of the protocol on the protection protocol family packet flow, the agreement includes the Encapsulating Security Payload protocol and authentication header protocol protocol used to ensure data confidentiality, reliability and integrity.......4.IPsec technology research between host-end security of data transmission,Thus providing a wireless LAN enables secure communication between the new way....... |
