Abstract

Because the conventional chaos masking communication scheme is vulnerable to dynamics-based and identification-based attacks, in this paper, we develop a robust digital secure communication scheme by exploiting sporadic coupling synchronization of the Lorenz system. The new scheme cannot only withstand the attacks effectively but also improves the frequency efficiency and noise resistibility, etc. The secure property and system performance are theoretically analyzed. Computer simulations are performed to illustrate the effectiveness and efficiency of our new scheme
