Abstract: Offshore wind power is an important part of the new power system. Due to the complex and changing situation in the oceans, its normal operation and maintenance cannot be done without information such as images; therefore, it is especially important to transmit the correct image in the process of information transmission. In this paper, we propose a new encryption algorithm for offshore wind power based on two-dimensional lagged complex logistic mapping (2D-LCLM) and Zhou Yi eight trigrams. Firstly, the initial value of the 2D-LCLM is constructed by the Sha-256 to associate the 2D-LCLM with the plaintext. Secondly, a new encryption rule is proposed from the Zhou Yi Eight Trigrams to obfuscate the pixel values and generate the round key. Then, 2D-LCLM is combined with the Zigzag to form an S-box. Finally, the simulation experiment of the algorithm is accomplished. The experimental results demonstrate that the algorithm is resistant to common attacks and has prefect encryption performance.

Keywords: image encryption; complex chaotic system; 2D-LCLM; Zhou Yi eight trigrams; offshore wind power.
