Design of a hybrid model for construction of digital chaos and local synchronization

作者：

Highlights：

• A hybrid model is proposed for the construction of digital chaos and achievement for synchronization.

• The digital chaos is rigorously approved for Devaney and Li-Yorke chaos.

• Local synchronization scheme can achieve synchronization without sending a drive signal to the receiver.

• A novel horn chaotic attractor is discovered.

• Simulations of chaotic characteristics and synchronization performance illustrate the results.
