The private key is stored on a removable storage device. A separate encryption accelerator component decrypts the encryption keys in order to encrypt and/or decrypt host data from a memory of a storage processor. The removable storage drive must be inserted into a receptacle of the encryption accelerator for encryption and/or decryption to be performed, since the encryption accelerator accesses the private key from the removable storage device in order to decrypt the encrypted controller key. The encryption accelerator generates key handles for the storage processor to use when requesting encryption and/or decryption operations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three layer key wrapping for securing encryption keys in a data storage system","description":"Securing encryption keys in a data storage system using three layer key wrapping that encrypts a data encryption key using a key encryption key, encrypts the key encryption key using a controller encr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9735962","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.
