Abstract
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.
