Abstract
Access of a user to a protected resource during a session is controlled by issuing an authentication information request and receiving authentication information from the user responsive to the authentication information request. The user is authenticated based upon verification of the received authentication information. One or more of the issuing, receiving and authenticating steps are repeated during the session to re-authenticate the user. At least a portion of the authentication information that is used during the re-authentication is different from a corresponding portion of the authentication information that was used during the initial authentication. A secure channel is optionally established between the user and the protected resource responsive to the initial verification. The secure channel can optionally be re-established with the re-authentication using the different portion of the authentication information.
