At this time, the RFID tag shares, with an RFID tag authentication server, the same message authentication code generation function, the RFID tag ID, the first challenge value, and the first response value generated by a PUF module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID tag authentication system","description":"An RFID tag using a physically unclonable function (PUF) generates a response value corresponding to a challenge value, receives an RFID reader ID from an RFID reader, generates a first message authen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9842234","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.
