T/WAPIA 007.8-2016 Wireless LAN product engineering guide Part 8: WAPI and IEEE 802.11ac
Basic Information
Scope
Scope: This guidance technical document specifies the key issues of the engineering implementation of the integration of WAPI and IEEE 802.11ac, mainly for the use of WAPI and support for the fast transmission function of IEEE 802.11ac. This guidance technical document is applicable to the engineering implementation of the integration of WAPI and IEEE 802.11ac standards; Main technical content: The 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; The core technology of IEEE 802.11ac is mainly based on IEEE 802.11a, which continues to operate in the 5.0GHz frequency band to ensure downward compatibility, but the data transmission channel will be greatly expanded, increasing from the current 20MHz to 40MHz or 80MHz, and even possibly reaching 160MHz. The theoretical transmission speed of the standard is expected to reach up to 1Gbps. Although the above two solutions involve different fields, there is no direct contradiction or conflict between them. They can be combined with each other and complement each other. For a basic introduction to WAPI and IEEE 802.11ac, please refer to Appendices A and B. The combination of WAPI and IEEE 802.11ac follows the following basic principles: a) Non-security solutions in wireless local area networks use IEEE 802.11ac; b) Security solutions in wireless local area networks fully use the WAPI mechanism; c) Security solutions for data transmission protection in wireless local area networks are combined by the WAPI confidentiality infrastructure and the frame encapsulation technology of IEEE 802.11ac.
