The time reference signal can include a time synchronization signal or a time distribution signal. The destination device can obtain attestation information from one or more fields of the time reference signal and determine whether the source device is authentic and trustworthy based on the attestation information. The destination device can also determine reliability or freshness of the time reference signal based on the attestation information. The time reference signal can be based on a Network Time Protocol (NTP), a Precision Time Protocol (NTP), or other protocol. The attestation information can include Proof of Integrity based a Canary stamp, a hardware fingerprint, a Secure Unique Device Identification (SUDI) of the source device, or an attestation key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authenticating time sources using attestation-based methods","description":"Systems, methods, and computer-readable media for authenticating time sources using attestation-based techniques include receiving, at a destination device, a time reference signal from a source devic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11245484","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.
