The server receives the message from the device and checks whether the hash corresponds to a one-time signing key for a root hash included in a public certificate associated with the identity, checks whether an index corresponding to the hash path from the one-time signing key to the root hash corresponds to a correct time slot, and determines it to be proven that the device is in possession of the correct one-time signing key when the checks are fulfilled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of proving validity and determining validity, electronic device, server and computer programs","description":"A device provides a one-time proof of knowledge about a one-time signing key to a server without revealing the one-time signing key by computing a hash as a hash function from the one-time signing key","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10511440","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.
