Abstract
A method and apparatus for providing mutual authentication between a user and a sending unit, (i.e. target resource) in one embodiment, includes determining, for a user that has been assigned an article, such as a card or other suitable article that has indicia thereon, desired sender authentication information that corresponds to actual sender authentication information that is embodied on the article. The sender authentication information can be located on the article by using the location information provided by the sending unit in a challenge. The method includes determining for the user, corresponding article identification information, such as a serial number that has been assigned to the article, or a shared secret, and sending a challenge for the user wherein the challenge includes at least location information, to allow the user to identify desired sender authentication information located on the article, and sending the article identification information.
