Rotating the initial symmetric key comprises rotating bits of the initial symmetric key to create a rotated key, the rotated key being different from the initial symmetric key. The method further comprises enciphering, by the key management server using the rotated key, data sent to a first client server. In another arrangement, a method for a client server to manage cryptographic key rotation comprises rotating, by the client server, an initial symmetric key based on a schedule. The method further comprises deciphering, by the client server, data sent from a key management server using the rotated key and providing the deciphered data to a user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive encryption rotation keys","description":"In one arrangement, a method for a key management server to manage cryptographic key rotation comprises rotating, by the key management server, an initial symmetric key based on a first rotation sched","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11240022","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.
