Abstract
Automatically re-authenticating a computing device seeking access to a network or a resource. A method comprises forwarding a request received from the computing device to an authentication device to enable the authentication device to authenticate the computing device using a full-authentication mechanism. State information related to authenticating the computing device is created from authenticating the computing device. The state information is received and stored. For example, an authenticator device that forwarded the initial authentication request from the computing device to the authentication device receives and stores the state information. The computing device is re-authenticated using the stored state information without again contacting the authentication device.
