An embedded processing system includes processing circuitry, a memory system, and a reprogramming control. The reprogramming control is configured to receive a transaction indicator and user credentials from a reprogramming system, the transaction indicator identifying a type of configuration item to program in the memory system. The reprogramming control is further configured to access user authentication data to authenticate authority of a user to program the memory system based on the transaction indicator and user credentials and receive an encrypted configuration item. The reprogramming control is further configured to decrypt and authenticate the encrypted configuration item as a decrypted and authenticated configuration item responsive to authenticating the authority of the user, and store the decrypted and authenticated configuration item in the memory system.

Secure reprogramming of embedded processing system

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.
