description	Embodiments of the present systems and methods may provide techniques to provide host side encryption while maintaining compression and deduplication benefits and providing communication between the host and the storage system that does not leak information about the data compressibility/deduplication properties. For example, in an embodiment, a method may comprise compressing, at a computer system, an original sector of data, generating a new sector of data including a first part including metadata and padding data, and a second part including the original sector of data that has been compressed and encrypted using a data encryption key (DEK), encrypting, at the computer system, the new sector of data using a data reduction key (DRK), and transmitting, at the computer system, the encrypted new sector of data to a storage system.
