Abstract
An embedded processing system includes processing circuitry, a memory system, and a reprogramming control. The reprogramming control is configured to authenticate a user associated with a reprogramming operation of the embedded processing system and receive an encrypted configuration item. The reprogramming control is further configured to decrypt and authenticate the encrypted configuration item either for storage of the configuration item in the embedded processing system or for transmission externally as an encrypted and signed entity. These operations are performed only after the user requesting such an operation has been authenticated to have the permission to perform the requested operation.
