Abstract
A system and method for updating multiple devices that are coupled to a network by a hub provides a trusted platform module in each of the devices, sends messages from the network to the hub for updating the devices, sends each of the devices messages from the hub to update the device, executes the content of each message in the device to which that message is sent, and deletes each message after it has been executed. Each of the messages preferably includes trusted code, and the device receiving each message executes the trusted code in the trusted platform module. The trusted code may include an update function, an image, and control data, and preferably has integrity. The hub may receive trusted code from a remote server, execute the trusted code to send a message to one of the devices, and then delete the trusted code.
