T/WAPIA 007.1-2010 Wireless LAN Product Engineering Implementation Guide Part 1: WAPI and IEEE 802.11n
Basic Information
Scope
Scope: This guidance technical document specifies the key issues of the engineering implementation of the integration of WAPI and IEEE 802.11n, including how to handle the quality of service control fields, the data composition of WPI integrity verification, WPI's A-MSDU encapsulation, WPI's A-MPDU encapsulation, data packet sequence numbers (PN) and replay counters, etc. This guidance technical document is applicable to the engineering implementation of the integration of WAPI and the IEEE 802.11n standard. Main technical content: - Wireless Local Area Network Authentication and Privacy Infrastructure (WAPI) provides a security solution for the data link layer in wireless local area networks, including identity authentication, key management, data encryption, data authentication, and replay protection; - IEEE 802.11n provides a solution for high transmission rates in the media access control and physical layer of wireless local area networks, including multiple-input multiple-output (MIMO), spatial multiplexing and mapping, antenna selection, and frame encapsulation. Since the two solutions involve different fields, there is no direct conflict or contradiction between them. They can be combined and complement each other. A basic introduction to WAPI and IEEE 802.11n is provided in Appendix A. The combination of WAPI and IEEE 802.11n follows the following basic principles: - Non-security solutions in wireless local area networks use IEEE 802.11n exclusively; - Security solutions for identity authentication and key management in wireless local area networks use the WAPI authentication infrastructure exclusively; - Security solutions for data transmission protection in wireless local area networks are combined by the WPI confidentiality infrastructure and the frame encapsulation technology of IEEE 802.11n (see Appendix B for the WPI confidentiality infrastructure).
