System and Method for Authentication

摘要

A multi-functional device is attached to a secure network and includes a control circuit. The control circuit receives indications as to whether a user is authenticated to use the multi-functional device and in response, generates and sends a control signal to the multi-functional device. As long as the multi-functional device continues to receive the control signal, the multi-functional device remains in an operational mode to allow the authenticated user to access the multi-functional device functions. If the multi-functional device ceases to receive the control signal, the multi-functional device deactivates itself.

1. A method for updating a secure device, the method comprising:
registering, with a network server, first and second addresses, wherein the first address is associated with a processing circuit of a computing device operatively connected to the secure device, and wherein the second address is associated with a processing circuit of the secure device; receiving, from the network server, a message comprising a destination address that corresponds to one of the first and second addresses; routing the update message to the processing circuit of the computing device if the destination address matches the first address; and routing the update message to the processing circuit of the secure device if the destination address matches the second address.
