The secret data item manager encrypts secret data items using a hardware encryption key and the Secure Element. It encrypts the transient secret cipher data with an account encryption key to generate and store repository account cipher data. It further encrypts the account encryption key to generate and store the repository account key cipher data with a root encryption key. The manager also derives a secondary encryption key from a user account password, encrypts the root encryption key with the secondary key to generate the transient root encryption key, encrypts the transient root encryption key using the hardware key to generate the repository root encryption key cipher data, and stores repository root encryption key cipher data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for protecting secret data items using multiple tiers of encryption and secure element","description":"A system and method for protecting secret data items using multiple layers of encryption with multiple encryption keys, a Secure Element, and a sandbox on an electronic device includes a secret data i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997191","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.
