AUTHENTICATION CERTIFICATE MANAGEMENT FOR ACCESS TO A WIRELESS COMMUNICATION DEVICE

摘要

A system and method for authenticating a user to a user device using two- factor authentication with a certificate. The status of the certificate is stored at the user device such that the stored status is queried during the authentication process. The status is updated as a background operation on the user device on a periodic basis. In the event that the user device fails to obtain updated status information, the frequency at which status update requests are issued by the user device are increased to a predetermined frequency or until a response is received.
