Abstract
A transmitter device (T) for secure communication includes: an encoder () configured to apply a non-systematic error correcting code (NS ECC) to a message, thus producing encoded bits with no clear message bits; and a transceiver () configured to transmit the encoded bits over a main channel to a receiver. A method for secure communication includes: encoding a message with an NS ECC to produce an encoded message carrying no message bits in the clear; and transmitting the encoded message over a main channel (). The NS ECC characteristics result in an eavesdropper channel error probability under a security threshold () and a main channel error probability over a reliability threshold (), whenever an eavesdropper () listening on an eavesdropper channel () is more than distance Z () from the transmitter. Unreliable bits in the encoded bits render the eavesdropper unable to reliably decode messages on the main channel.
