  • Patent number: 10263777
    Abstract: Organically Derived Synchronized Processes provide encryption parameter management in a certificate-less system. A first node generates a parameter data set containing multiple values; uses a seed value stored at the first node to select values from a random parameter data set to form a parameter subset; generates encryption parameters using the subset; encrypts user data using the encryption parameters; generates a signature based at least on the parameter data set; and transmits a start frame including the parameter data set, the encrypted user data, and the signature. A second node receives the start frame; uses a seed value stored at the second node to select values from the received parameter data set to form a parameter subset; generates decryption parameters using the subset; decrypts the user data using the decryption parameters; and verifies the received signature. The encryption and decryption parameters are then applied to further payload data.
