The industrial Internet of Things (IoT) is a trend of factory development and a basic condition of intelligent factory. It is very important to ensure the security of data transmission in industrial IoT. Applying a new chaotic secure communication scheme to address the security problem of data transmission is the main contribution of this paper. The scheme is proposed and studied based on the synchronization of different-structure fractional-order chaotic systems with different order. The Lyapunov stability theory is used to prove the synchronization between the fractional-order drive system and the response system. The encryption and decryption process of the main data signals is implemented by using the n-shift encryption principle. We calculate and analyze the key space of the scheme. Numerical simulations are introduced to show the effectiveness of theoretical approach we proposed.
