The first value corresponds to a physically unclonable function (PUF) of the chip. The second value is a key including information indicating a type of obfuscation performed to obfuscate the first opcode command as the second opcode command. The third value may be an inversion flag indicating a type of obfuscation performed to obfuscate the first opcode command as the second opcode command."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for obfuscating opcode commands in a semiconductor device","description":"A method for securing an integrated circuit chip includes obtaining a first value from a first storage area in the chip, obtaining a second value from a second storage area in the chip, generating a t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11509461","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
