Design, Secure Communication Scheme Based On Dsp Technology

Several years ago, it's generally considered that encryption could make communications safe and secret, so encryption technique was widely used in the field of the secure communication. However, with the developments of computer, there are more and more problems on encryption rising in this field, which are brought by encryption self. Therefore, academic community gradually pays more attentions to information hiding techniques. And now, information hiding has been an important technique in the field of the secure communications.Considering its research value, which is advancing continuously, we choose the application of information hiding techniques in the field of the secure communication as a subject to research. And by using this technique, we develop a secure communication system based on DSP.At the beginning of this paper, we give a review of information hiding techniques and DSP techniques. Then we introduce the design of this secure communication system based on DSP and analyze the feasibility of this system. Following that, we also discuss many problems on system's software design. At last the conclusion of this paper is given.
