Unlike traditional security communication systems, unconditional security communication system takes the advantage of the channel noisy to keep the transmitted signals secret to Eve while the legitimate partners can receive the signals perfectly without distribution and management of the secret keys. Security coding is important to an unconditional security communication system. The basic principle of the security codes is introduced and the analysis of security properties is given. Finally, extensive simulations are conducted by using the security code constructed from the optimal error-checking binary primitive BCH code and the non-optimal error-checking binary primitive BCH code as security codes.
