1. What is a wapi certificate?
Wapi (wireless local area network authentication and privacy infrastructure) is a wireless security standard based on 802.5438+0 1 wireless fidelity proposed by China.
WAPI has two authentication methods, namely certificate authentication method and pre-key authentication method. WAPI digital certificate is a document signed by PKI (Public Key Infrastructure) certification authority, which contains public key and user-related information, and is the digital identity certificate of network users. The digital certificate used by WAPI system is verified by AS to determine the uniqueness and legitimacy of WAPI user identity.

WAPI adopts a more reasonable two-way authentication encryption technology, which realizes the identity authentication, link verification, access control and encryption protection of user information in wireless transmission state. Completely reverse the coexistence and incompatibility of various security mechanisms adopted by WLAN, and fundamentally solve the security problems and compatibility problems.
At present, there are two standards in the global WLAN field. One is the IEEE 802. 1 1 series standards proposed by American Industrial Standards Organization (commonly known as Wi-Fi, including 802. 1 1a/b/g/n/ac, etc. ), and the other is the WAPI standard proposed by China. Simply put, WAPI is the first secure access technical standard with independent innovation and intellectual property rights in the field of computer broadband wireless network communication in China, and it is the security mechanism in the mandatory standard of wireless local area network in China.
For ordinary users, enabling WAPI can enhance the security of WiFi, and has little impact on user experience such as network speed. However, as a WLAN security standard customized by China itself, it helps to reduce dependence on foreign patents.
