Abstract: Designs of integrated modules for securing data are described. According to one aspect of the present invention, a data set is distributed among a plurality of data channels, each of the data channels including an encrypting/decrypting module designed to process a data stream or set. Modules in the data channels work independently from each other. A next data stream is timely provided to a data channel when a current data stream is about to finish, resulting in increased efficiency when encrypting data from a source or decrypting encrypted data for a source.
