Abstract
An apparatus and method for encrypting messages from a first node splits the message into a plurality of message units, each of which is encrypted. The encrypted message units are split into path units, each of which is directed to a different route path to a destination node. At the destination node, the path units are received and reassembled into encrypted message units, which are decrypted into message fragments and concatenated to form a message corresponding to the original one sent.
