Abstract
One embodiment provides an apparatus adapted to perform a secure firmware upgrade. The apparatus includes a first memory and a second memory. The first memory stores a private key for use in decrypting content and a unique identifier corresponding to the apparatus. The second memory includes a first version of firmware for the apparatus. The apparatus further includes a controller configured to perform an operation that includes receiving a first request to perform a firmware update operation for the apparatus. The operation also includes transmitting a second request for a second version of firmware to a remote server, the second request specifying the unique identifier corresponding to the apparatus. Additionally, in response to transmitting the second request, an encrypted firmware package is received from the remote server. The operation further includes decrypting the encrypted firmware package using the private key and installing the decrypted firmware package on the apparatus.
