Since the oracle responses in test mode do not correspond to the functional key, satisfiability (SAT) attacks are not able to leverage the responses from the scan chain. In addition, a charge accumulation circuit is developed to prevent and detect any attempt to enter the partitioned test mode while the correct circuit responses are still stored within the registers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing logic locking key leakage through the scan chain","description":"A proposed technique allows for the security of the logic cone through logic locking and secures the outputs of the circuit from the scan chain without modifications to the structure of the scan chain","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11971987","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.
