Abstract

See full text

A mailbox mechanism is used for communication of secure messages from a server to the firmware of a device. Mailbox content provided by the server is authenticated in a driver execution environment of the device, using reboots across the communication sessions, and then stored in secure storage. The communication sessions include first receiving a signed server key, and then receiving a message from the server that is based on a hash of a nonce generated by the device.
