Basic Information
Scope
Scope: This guidance technical document specifies the key issues of the engineering implementation of the integration of WAPI and IEEE 802.11ad, mainly providing switching functions for STAs that use WAPI and support multi-frequency/channel switching, as well as support for GCM-SM4. This guidance technical document is applicable to the engineering implementation of the integration of WAPI and the IEEE 802.11ad standard. 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. IEEE 802.11ad uses the 60GHz spectrum of high-frequency carriers and achieves simultaneous transmission on multiple channels with the support of MIMO technology, with each channel's transmission bandwidth exceeding 1Gbps and reaching 7Gbps. IEEE 802.11ad is mainly used to implement the transmission of high-definition audio and video signals within households, providing a more complete high-definition video solution for home multimedia applications. Ideally, it is most suitable for use as a high-speed wireless transmission channel between various devices in the room. Although the two solutions involve different fields, there is no direct conflict or contradiction between them, and they can be combined and complement each other. For a basic introduction to WAPI and IEEE 802.11ad, please refer to Appendix A and Appendix B. The combination of WAPI and IEEE 802.11ad follows the following basic principles: a) Non-security solutions in wireless local area networks are fully implemented using IEEE 802.11ad; b) Security solutions in wireless local area networks are fully implemented using 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
