Abstract
Before a relying party grants a client access to a resource, the last use of the security token by the client to access the resource of the relying party can be verified. Verification can be accomplished by comparing the last time the client sent the security token to the relying party with the last time the relying party received the security token from the client. If the last use of the security token is not verified, the possibility exists that the security token has been fraudulently used by a third party.
