Abstract
The present disclosure relates to a method including executing, by an electronic device, a first firmware module stored in a volatile memory of the electronic device, the execution of the first firmware module causing an updated firmware key to be stored in a non-volatile memory of the electronic device, and uploading a second firmware module to the electronic device. The method also includes decrypting the second firmware module by a cryptographic processor of the electronic device based on the updated firmware key, and installing the decrypted second firmware module in the volatile memory of the electronic device at least partially overwriting the first firmware module.
