Latest Patents
One of his latest patents is titled "Autotest of encryption algorithms in embedded secure encryption devices." This invention features an internal state machine controller in an integrated circuit that independently tests and verifies encryption and decryption algorithms with minimal processor intervention. The cryptographic implementation generates all input data autonomously, allowing for simultaneous testing of other integrated circuit components. The processor loads predetermined test vectors and signals the state machine to initiate testing cycles, ensuring that the output matches the original data.
Another significant patent is "Automatic data generation for self-test of cryptographic hash algorithms." This innovation includes a hardware hash algorithm block that autonomously generates data to hash from its initialization values. This approach eliminates the need for continuous input data, thereby reducing firmware sizes and overall test costs. The hardware can run unattended, creating additional sub-blocks from the initial data using a hardware expansion function, which enhances fault coverage.
