PKI in WAPI Networking

PKI in WAPI Networking

Figure 15-4 shows an example of networking of WLAN authentication and privacy infrastructure (WAPI) networking.

Figure 15-4  Networking of a WAPI application

WLAN stations (STAs) use the WAPI certificate authentication mode (WAPI-CERT) to connect to the Internet. The authentication service unit (ASU) authenticates STAs and access points (APs). The CA server issues certificates. Generally, the ASU and CA server are deployed on the same device.

During WAPI-CERT authentication, both STAs and APs must be authenticated. Before authentication, STAs and APs must obtain their certificates. The ASU checks their certificates to authenticate them.

An AP does not check an STA's certificate. Instead, it sends its own certificate and the STA's certificate to the ASU for authentication.

In WAPI applications, the PKI module reads a certificate file from a device's storage device and loads the certificate to the memory.
