Abstract

A method for remotely updating the behavior and state of a medical device or the firmware itself of a medical device, not requiring physical access to the device, that occurs through an encrypted and authenticated communication channel. The behavior and state of the device may be modified from a healthcare provider interface through a transmission method. The firmware of the medical device may be modified by the use of over the air device firmware updates, created from a designated secure machine called a build machine described herein. Both actions are transmitted to a server and then forwarded to a companion device and are particularly designed so that the server never stores sensitive cryptographic material in the event of server compromise. The companion device forwards the update to the medical device, which decrypts and validates the update or command before performing the change.
