Abstract
An apparatus including a processor caused to: receive sizes and data block encryption data for multiple encrypted data blocks from multiple node devices, wherein data block encryption data is separately generated and used by each node device to encrypt a portion of a data set to generate one of the multiple encrypted data blocks; for each encrypted data block, generate a corresponding map entry within map data to include size and data block encryption data; and in response to receiving size and data block encryption data for all encrypted data blocks, encrypt a portion of the map data to generate an encrypted map base, wherein the portion of map data includes at least a subset of the multiple map entries, and transmit the encrypted map base to one or more storage devices to be stored within a data file along with the multiple encrypted data blocks.
