The WLAN security standard protocol with independent intellectual property rights in China is called the WAPI standard, while the international standard is the 802.11i standard. Both are protocols on wireless access security, and both aim to ensure the security of wireless network access and wireless data communication. The difference is that 802.11i only defines security guarantees for wireless clients, while WAPI defines authentication for both wireless clients and wireless access points, and the corresponding data encryption algorithms are different. What's more, it is private.
