Systems, methods, and media for improving security of a packet-switched network

A machine-accessible medium containing instructions effective, when executing in a data processing system, to cause said data processing system to perform operations comprising:

• assembling by a sender computer system one or more packets based on the information to be transmitted, at least one of the one or more packets having an encrypted payload comprising the information to be transmitted;
• inserting by the sender computer system Additive Gaussian White Noise into one or more of the packets;
• and
• transmitting by the sender computer system the one or more packets with inserted Additive Gaussian White Noise over the network.

A sender computer system for transmitting information over a network, the system comprising:

• a TX unit, the TX unit being adapted to facilitate transmission of the information to a receiver computer system via the network;
• a packet module of the TX unit, the packet module being adapted to break the information to be transmitted into one or more packets;
• and
• an Additive Gaussian White Noise module in communication with the packet module, the Additive Gaussian White Noise module being adapted to insert Additive Gaussian White Noise into one or more of the packets.
