Abstract
Automatic recovery from loss of a security token on an embedded device is achieved by having a service provider (SP) server send to a device server a backup copy of the security token in conjunction with sending to an embedded device a primary copy of the security token, and retrieving from the device server and sending to the embedded device the backup copy of the security token upon detecting that the primary copy of the security token has been lost. The method and system obviate the need for a user to have to re-input on the embedded device a credential that is represented by the security token in the event the primary copy of the security token is erased from the embedded device or otherwise becomes inaccessible to the embedded device.
