Latest Patents

One of Bridgford's latest patents is titled "Method and integrated circuit for protecting against differential power analysis attacks." This invention provides a method for safeguarding the security of programmable integrated circuits by decrypting a portion of an encrypted bitstream using a cryptographic key stored within the IC. The invention tracks the number of failures to decrypt the bitstream and retains this information across power cycles. If the number of failures exceeds a predetermined threshold, the IC stores data that prevents the decryption key from being used for future decryptions.

Another significant patent is "Methods and systems with transaction-level lockstep." This invention outlines methods for the redundant operation of two processors executing a set of instructions in parallel. The first processor suspends its operation in response to a first access transaction for a peripheral device. The write transaction is not issued until the second processor executes the instruction and issues a corresponding access transaction. This ensures that both processors operate in sync, enhancing reliability.
