To realize concealed communication of information in wireless sensors networks,a novel covert communication system based on random noise modulation is proposed in this paper. The correlation coefficient of a joint normal distribution noise sequence is modulated by a binary stream to achieve a covert communication system. Then the joint normal distribution noise is superimposed on the output of the digital modulator of the conventional communication system. At the receiving end,the correlation coefficient is estimated from the received signal and the covert binary stream is recovered by a hard decision. The key issues of the proposed scheme,such as channel estimation and symbol synchronization,are solved by the conventional digital communication system. The bit error rate of the proposed covert communication system is derived theoretically. Simulation results show that the proposed covert system has good bit error rate performance and is consistent with the theoretical derivation.
