  • providing one or more portable client devices, each of the client devices equipped with a short-range wireless communications capability for communicating in the short-range wireless networking environment;

    receiving, by a network access point, a communication from a selected one of the client devices;

    determining, by the network access point, that the selected client device does not have a valid session key for encryption;

    obtaining, by the network access point, user credentials for a user of the selected client device;

    authenticating, by the network access point, the user credentials by contacting an authentication server;

    establishing the valid session key when the authenticating step completes successfully; and

    using the established session key, by the selected client device and the network access point, to encrypt packets that are transmitted over a link between the selected client device and the network access point.
