The network access standard designation may be provided by the mobile network access device to an online signup server via a EKU_key_purpose field of a PKCS10 certificate signing request. The device identification datum may be provided to the OSU via a subject field of the signing request. The OSU may require that the device identification datum be the same as a device identification datum provided by the mobile network access device prior to the mobile network access device requesting a signed network access certificate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Restricted certificate enrollment for unknown devices in hotspot networks","description":"A network access system, e.g. a network hotspot, requires a mobile network access device, e.g. a smart phone or WiFi only device, to provide a network access standard designation and/or a device ident","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660977","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.
