Design And Implementationofpre-Configure Incubation OFAP-Side And Ipsec Connection Managementmodule In Wlan System

With the wide application of wireless communication technologythe traditional local area network has been increasingly unable to meet the needs of people, so the wireless LAN (Wireless Local Area Network, WLAN) came into being, and rapid development. Although the wireless LAN can’t be completely independent of the wired network, but in recent years, wireless LAN products have matured to its superior flexibility and ease of network applications play an increasingly important role.At the same time, we must protect the data transmitted between the system and the, so that it has a certain degree of security.Establish a secure connection between the different platforms have one of the most commonly used method is to use IPSEC (IP Security Protocol:IP Security Protocol). In the network IP layer, IPSEC provides encryption services to support data origin authentication, ta integrity and confidentiality. IPSEC use is completely transparent to users and network applications are making a very attractive solution to improve the security of existing network services.AC (Access Point) and AP (Access Control) to establish the IPSEC wireless connection to wired to provide cryptographic services to ensure data security.Establish an IPsec connection must be applied to a protocol that allows them to carry out the interconnection and communication between the AC-AP, which is the CAPWAP-Control AND Provisioning of Wireless Access Points Protocol SpecificationConsists of two parts:CAPWAP protocol and the wireless BINDING agreement. The former is a generic tunneling protocolto complete the AP found AC, basic agreementand unrelated to a specific wireless access technology. The latter is to provide a specific and a wireless access technology, configuration management capabilities.In this article, the first protocol802.1In wireless transmission standard, and describes their common security protocols.Secondly, the basic process to establish a the IPSEC wireless connection in AC (Access Point) and AP (Access Control), the common tunneling protocol CAPWAP. Finally, the AP side for IPSEC established key incubator module analysis and design.
