A comparator executes a comparative process of the request signal and the request signal by using average values of the reception strength measured by the strength meter. A variation calculator calculates variation in the reception strength measured by a plurality of times in the strength meter regarding the request signal. The comparator, in a case where the variation in the reception strength exceeds a threshold value indicating a communication failure in the request signal, determines the relay attack regardless of a result of the comparative process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Relay attack determination device","description":"A strength meter in a relay attack determination device is disposed on a portable device and measures a reception strength by a plurality of times in each of a request signal and a request signal rece","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11963011","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.
