Systems and methods are provided for sending and receiving encrypted submessages. Messages could be partitioned into a plurality of submessages based on the content of a message, and such submessages could be individually encrypted and sent over a network. The partitioning could be based on various standards and/or heuristics. In the sending process, submessages could be designated to travel over different networks and networks of different types. Such submessages could then be received and reassembled in spite containing overlapping content with respect to each other, having to contend with copies of submessages, and having accompanying related content (e.g., advertisements) and non-related content (e.g., random bits). Moreover, the sending process could also be performed in real time or in a batched manner, depending on the implementation.
