Abstract: A data storage system is provided. The system includes an electronic storage architecture configured to be coupled to a computing system and a storage medium. The architecture mediates the storing and accessing of data at the storage medium in response to the commands to write or read data. The architecture includes a file interface configured to process at least one attribute associated with data. The architecture includes a crypto interface configured to encrypt and decrypt the data based on the at least one attribute. The at least one attribute specifies a classification level of the data. The crypto interface includes cryptographic functions. Each cryptographic function is associated with a different classification level. The architecture includes a storage interface configured to provide a mapping between partitions on the storage medium and the cryptographic functions. Each of the partitions is associated with a different classification level.
