The method comprises the following steps: deriving a secret key for the derived authentication entity from the secret key of the original data carrier by the original data carrier; forming derivation data for the derived authentication entity; transferring authentication data to the derived authentication entity, wherein the authentication data have the derivation data, the certificate of the public key of the original data carrier as well as a derived key pair which comprises the derived secret key and the public key of the original data carrier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for creating a derived entity of an original data carrier","description":"There is provided a method for creating an authentication entity derived from an original data carrier, wherein the original data carrier has a key pair that is individual to the original data carrier","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722800","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.
