METHODS AND SYSTEMS FOR REPLACING SHARED SECRETS OVER NETWORKS

A method for replacing a shared secret over a network is provided that includes determining that a security breach could have occurred, determining that a shared secret of a user is to be replaced, and transmitting a renewal message to an authentication system requesting a new shared secret and an associated effective life for the user. Moreover, the method includes generating a new shared secret and an associated effective life at the authentication system for the user, and replacing the shared secret and associated effective life in an enrollment data record of the user with the new shared secret and associated effective life. Furthermore, the method includes transmitting the new shared secret and associated effective life to a communications device associated with the user, and replacing a shared secret and associated effective life stored in the communications device with the new shared secret and associated effective life.
