Communication in star coupled network with fractional hyperchaotic nodes

Encrypted confidential information via complex network synchronization of N-coupled fractional-order hyperchaotic nodes in star configuration is numerically reported. In particular, we resort to recent results from complex networks to achieve network synchronization with star topology, we show the conditions for achieve this synchonization with 5 nodes. Encryption, transmission, and decryption of confidential information in hyperchaotic communications are also presented. In particular, we show a section of a song encrypted, transmitted and retrieved, we obtain at the multiple receivers that, the original audio message is appropriatelly recovered.
