Communication Method for Chaotic Encryption in Remote Monitoring Systems for Product e-Manufacturing and e-Maintenance

摘要

In chaotic cryptosystems, it is recognized that using (very) high dimensional chaotic attractors for encrypting a given message may improve the privacy of chaotic encoding. In this paper, we study a kind of hyperchaotic systems using some classical methods. The results show that besides the high dimension, the sub-Nyquist sampling interval is also an important factor that can improve the security of the chaotic cryptosystems. We use the method of time series analysis to verify the result.
