  • Configuration based cryptographic key generation
    Patent number: 10708073
    Abstract: In some examples, a programmable device may load configuration data into a configuration storage to configure programmable logic of the programmable device. The programmable device may include a key generation logic that may read at least a portion of the configuration data from the configuration storage. The key generation logic may generate a cryptographic key based at least in part on the at least a portion of the configuration data read from the configuration storage.
    Type: Grant

    Date of Patent: July 7, 2020
    Assignee: Honeywell International Inc.
    Inventors: John D. Profumo, Thomas Cordella, James L. Tucker
  • Encryption using entropy-based key derivation
    Patent number: 10013363
    Abstract: A system may encrypt the contents of a memory using an encryption key that is generated based on an entropy-based key derivation function. The system may generate a random value as a key split associated with an instance of writing data to memory. The system may generate an encryption key for encrypting the data using an entropy-based key derivation function based at least in part on the key split. The system may encrypt the data using the encryption key. The system may store the encrypted data and the key split to the memory.
