1. A security procedure for communications between a wireless local area network and a client device, the wireless local area network having access points connected to an authentication server, said procedure comprising the steps of:
- identifying, by a client device, an access point of the wireless local area network; and
performing an authentication process for authenticating the client device by exchanging management frames between the client device and the authentication server through the access point, wherein IPsec security is invoked for communications between the client device and the authentication server during the authentication process.
