An encryption/decryption engine, located within a first of the power domains, generates encrypted data in response to received packets and cryptographic primitives. An authentication engine, located within a second of the power domains, performs authentication operations in response to the encrypted data. The encryption/decryption engine comprises an advanced encryption standard engine that forms the cryptographic primitives and is located within a third of the power domains. The third power domain enters the reduced power state for part of a period during which (i) the first power domain does not enter the reduced power state and (ii) the encryption/decryption engine is generating the encrypted data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"MACSec implementation","description":"A media access control (MAC) security apparatus for a local area network interface includes multiple independently controlled power domains, each of which enters and exits a reduced power state indepe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8543826","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.
