Server authentication verification method on user terminal at the time of extensible authentication protocol authentication for Internet access
First Claim
1. A server certificate verification method performed by a wireless LAN user terminal during Extensible Authentication Protocol authentication for Internet access, the method comprising:
- (a) receiving a server certificate from a wireless LAN authentication server, and transmitting a server certificate verification request message of the server certificate to a wireless LAN authentication server via a wireless LAN access server;
(b) transmitting by the wireless LAN authentication server an On-line Certificate Status Protocol request message to an On-line Certificate Status Protocol server to verify the server certificate;
(c) receiving a result of the server certificate verification performed by the OCSP server using an Extensible Authentication Protocol packet from the wireless LAN authentication server; and
(d) determining whether the result of the server certificate verification is valid.
