However, the WEP mechanism has been widely proven to not have the same security as wired networks, so it is not adopted. This section adopts the WAPI mechanism to implement the security of wireless LANs, and in accordance with the Regulations on Commercial Information Code Management issued by the State Council of the People's Republic of China on October 7, 1999, it has been submitted to the Office of the State Cryptography Administration for review and approval. The key points of the WAPI mechanism are stated in Chapter 1 "Authentication and Confidentiality" of this section. The WAPI mechanism used in this part was submitted to relevant institutions with the right to receive WAPI, and was approved after review. The Ethernet type field (EtherTypeField) 0x8B1 was allocated for this mechanism: Due to the difference in authentication and confidentiality mechanisms, the corresponding specifications, tables and contents except for Chapter 1 have been adjusted: - Related to WAPI, the original 5.1.3 "Authentication" was changed to "Link Authentication". The original 5.4.3.4 "Confidentiality" was also modified.
