  • Patent number: 11784987
    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.

  • Publication number: 20230244765
    Abstract: An embedded processing system includes processing circuitry configured to execute a plurality of computer executable instructions. The embedded processing system also includes a memory system configured to store a plurality of configuration items, where at least one of the configuration items includes a sequence of the computer executable instructions. The embedded processing system also includes an authentication control configured to authenticate an immutable anchor associated with the embedded processing system, authenticate integrity of a reconfigurable entity map associated with the memory system, authenticate the configuration items based on the reconfigurable entity map, and perform an accommodation measure based on an authentication failure of at least one of the configuration items.

  • Patent number: 11470062
    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.
