The probe calculates propagation timing between a reception time of the message and a reception time of an associated reflection signal transmitted in response to the message and determines validity of the message according to a match between the calculated propagation timing and a predefined propagation timings associated with the bus connected units. Wherein the bus connected units are statically connected to the bus between the first point and the second point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Message authentication based on a physical location on a bus","description":"A system for authenticating messages transmitted on a bus based on physical location of transmitting units, comprising a reflector adapted to inject a plurality of reflection signals at a first point ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11245550","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.
