TL;DR: Simulations and performance evaluations show that the proposed system is able to produce many 1D chaotic maps with larger chaotic ranges and better chaotic behaviors compared with their seed maps.

TL;DR: This paper introduces a new parametric switching chaotic system (PSCS) and its corresponding transforms for image encryption and shows more general properties, including the Sine and Tent maps as special instances.

TL;DR: This paper introduces a discrete wheel-switching chaotic system (DWSCS) and proposes a pseudo-random number generator using DWSCS whose excellent performance has been shown in experiments and comparisons.

TL;DR: Performance evaluation and security analysis demonstrate that the proposed SMIE-SIS with arbitrary settings has at least five advantages: it is able to fully recover the original image without any distortion; it has much lower pixel expansion than many existing methods; its computation cost is much lower than the polynomial-based secret image sharing methods.

TL;DR: Computer simulation and security analysis demonstrate that the proposed image encryption scheme shows excellent encryption performance, high sensitivity to the security keys, and a sufficiently large key space to resist the brute attack.
