Application: System and method for obfuscation of sequential logic through encryption (Patent ID: US20240020424A1)

The patent filed by L3Harris Technologies Inc. describes systems and methods for protecting the intellectual property of a circuit by obfuscating logic through encryption. The method involves analyzing a combinational circuit to identify specific logic gates that perform certain functions, dividing the circuit into protected and unprotected portions, storing information implementing the identified functions in an encrypted format in a memory device, and interfacing the remaining logic gates with the memory device to generate outputs based on the stored information. This approach ensures that the functions are obfuscated when the circuit is at rest, enhancing security.

The claims associated with the patent detail the specific steps involved in the method, such as identifying logic gates based on their performance and complexity, decrypting information upon circuit enablement, generating outputs based on decrypted information, and removing decrypted information upon detection of trigger events. The circuit described in the patent includes logic gates, a memory device storing encrypted information, and a processor responsible for decrypting information, generating outputs, and managing the removal of decrypted data. The circuit ensures that the functions of the protected portion remain obfuscated when the circuit is inactive, providing a robust intellectual property protection mechanism.
