Abstract
The subject disclosure is directed towards encryption and deduplication integration between computing devices and a network resource. Files are partitioned into data blocks and deduplicated via removal of duplicate data blocks. Using multiple cryptographic keys, each data block is encrypted and stored at the network resource but can only be decrypted by an authorized user, such as domain entity having an appropriate deduplication domain-based cryptographic key. Another cryptographic key referred to as a content-derived cryptographic key ensures that duplicate data blocks encrypt to substantially equivalent encrypted data.
