One method involves generating an encryption key for use in encrypting data and generating an identifier for the data. Generation of the encryption key is based upon a hash of the data to be encrypted, and generation of the identifier is based upon the data to be encrypted and/or the encryption key. The method also involves detecting whether an encrypted copy of the data is already stored by a storage system, based upon the identifier. The method also detects whether a higher level of security has been specified for the data and, if so, modifies the data to be encrypted or the encryption key, based upon a client-specific value, prior to generating the identifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selectively protecting against chosen plaintext attacks in untrusted storage environments that support data deduplication","description":"Various methods and systems for selectively protecting against chosen plaintext attacks when encrypting data for storage on an untrusted storage system are disclosed.
