Abstract
A processing device executing a wide area network (WAN) accessible service receive an encrypted digital image comprising a firmware update for an embedded system of a device having a specific device serial number (DSN). The processing device additionally receives device related information from a computing device, wherein the device related information comprises the DSN of the device comprising the embedded system and a version number of a current firmware component installed on the embedded system. The processing device determines, using the device related information, that the encrypted digital image for the device is available. The processing device then provides the encrypted digital image to the computing device for use by the computing device to update a firmware version of the embedded system.
