The cryptographic operation includes segmenting a first data stream into a first plurality of data stream fragments, segmenting a first data stream fragment of the first plurality of data stream fragments into a first numeric value and a second numeric value, identifying, using the first numeric value, a first encryption key of the set of encryption keys, and applying a one-way cryptographic function to the first encryption key a first number of times determined by the second numeric value to generate a transformed fragment having a value that depends on the values of the first numeric value and the second numeric value from the first data stream fragment and a value of the first encryption key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical unclonable function-based encryption schemes with combination of hashing methods","description":"A system is configured to derive a set of encryption keys from measured device characteristics of at least one PUF device and communicate with a remote device by performing a cryptographic operation s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11496326","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.
