The vehicle-mounted terminal transmits its position information to the first server. The certificate authority acquires information about a vehicle-mounted terminal likely to appear according to place and time from the first server. The certificate authority allows the second server to verify validity of a certificate for a vehicle-mounted terminal acquired from the first server. The certificate authority generates a first list of vehicle-mounted terminals having valid certificates and a second list of vehicle-mounted terminals having invalid certificates according to place and time based on a verification result. The certificate authority transmits the first and second lists to the roadside device and the vehicle-mounted terminal. The roadside device and the vehicle-mounted terminal verify a certificate using the first and second lists."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system, vehicle-mounted terminal, roadside device","description":"A communication system (10) includes a certificate authority (100) for performing authentication, a roadside device (110), a vehicle-mounted terminal (120), a first server (130), and a second server (","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9601016","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.
