Secure communication using multichannel noise

Abstract:

A method, apparatus and computer program product for secure communication includes receiving a message for transmission from a transmitting node to a receiving node. The message is split into a plurality of channels and each channel receives an identical copy of the message. Noise data is added to each version of the message. The noise data is different for a respective copy of the message than any other version of the message thus producing a plurality of ciphers each for a respective channel. The ciphers are transmitted via the respective channels from the transmitting node to the receiving node.
