This paper presents a novel invertible 3D maps based image encryption method. A 2D gray-level image is represented as an array of gray level values of the pixel, which can be considered as the third dimension. An invertible 3D maps are presented and utilized for image encryption. The proposed scheme combines the permutation and the substitution using the invertible 3D maps. All bits in the image data matrix are permuted during the operation of the 3D maps. Therefore 2D positions of image pixels are permuted, and 1D grey level values of the pixels are also substituted, that is two processes of image encryption, permutation and substitution, are performed simultaneously. The security abilities of the scheme are analyzed evaluated in detail, which shows that it has high level security. Simulation results validate the effectiveness of the proposed image encryption method.

Online SoC estimation for Li-ion batteries: A survey explore the distributed secure cloud management to battery packs

In order to enhance the stability, the control scheme for the wind power generation should have strong robustness. Sliding mode control is powerful to reject disturbance and has good robustness. However, sliding mode control is a fast switching control essentially. While accelerating the speed to reach the sliding surface, it will result in large chattering which can induce high-frequency oscillation of the output of wind power generation system. This paper proposes a novel chattering-free terminal sliding mode control based on the vector control technology, and applies it to control direct driven permanent magnet synchronous generator(PMSG). Speed and dq-axis current regulator are designed to ensure the rotor speed and current to reach the given values in finite time, respectively. The method proposed can estimate the chattering and enhance the system dynamic and static performance. Compared with PI control, the simulation results verify that the speed and current can track the given value more rapidly. Moreover, it has strong robustness to disturbance.
