Each encryption tier in the system can include a node programmed to service encryption and/or decryption requests, a key store to store encryption keys, and an audit log to store key identifiers. Each computing node may include a background module that continuously or periodically verifies the integrity of keys. For example, the background module may retrieve an identifier in the audit log, retrieve the object stored at a location in the key data store identified by the identifier, decrypt the encrypted key in the object, and use the decrypted key to decrypt the encrypted identifier in the object. The identifier is compared with the decrypted identifier, and if the identifiers do not match, the background module generates an alert indicating that the key is not valid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Verification of stored encryption keys in multi-tiered encryption system","description":"A background module in a multi-tiered encryption system verifies the integrity of keys used to encrypt and decrypt data.
