System and method for delivering a challenge response in an authentication protocol

摘要

A system and method for authenticating a user that includes receiving an access-request of a network protocol at a challenge-response server; determining if an access-challenge message is required; delivering an active script component through a parameter of an access-challenge message of the network protocol when an access-challenge is required; receiving a challenge-response of a user; validating the challenge-response; and selectively sending an access-accept response for a valid challenge-response and sending an access-denied response for an invalid challenge-response.
