Against the shortcoming of previous secure communication system such as high complexity and difficult physical implementation,the pseudo-random sequence hopping based secure communication is proposed.In this method,both of the communication sides use synchronous n-order m-sequence to control the modem hopping,so that it is difficult for the third party to capture the effective information and the secure communication is realized.on Matlab simulation platform,the second-order m-sequence is used to control three kinds of simple modem hopping.The simulation result shows that reliable communication can not be achieved by using non-synchronous demodulation while the proposed communication method is simple and secure.
