Abstract

Generally speaking, the discrete map possesses a low dimension and complex dynamics that can trigger hyperchaos to apply in image encryption. In this paper, we lead a memristor possessing cosine mem-conductance into the one-dimensional (1D) Chialvo map by sinusoidal-modulation-input method, thereby a two-dimensional (2D) memristive Chialvo (m-Chialvo) map is constructed. The fixed points stability and the forming mechanism for initial-boosted behavior are theoretically deduced. Numerical simulations show that the 2D m-Chialvo map can trigger initial-boosted hyperchaotic attractors, which hold the availability for image encryption. Besides, an FPGA-based digital platform is implemented to offer the verification of the initial-boosted hyperchaotic attractors. Furthermore, an STM32-based image encryption algorithm with hardware implementation is designed by deploying the coexisting hyperchaotic sequences, and the encrypted images can pass various performance tests. This verifies the feasibility of the hyperchaotic sequences for the algorithm in STM32-based image encryption with hardware implementation.

记忆性 Chialvo 地图中的初始增强动力及其在图像加密中的应用与硬件实现

一般来说，离散图的维度较低，动态复杂，在图像加密中可能引发超混沌。本文通过正弦调制输入法，将具有余弦忆导的忆阻器引入一维（1D）Chialvo 映射，从而构建了二维（2D）忆阻式 Chialvo 映射（m-Chialvo）。理论推导了定点稳定性和初始增强行为的形成机制。数值模拟表明，二维 m-Chialvo 图可以触发初始增强超混沌吸引子，从而为图像加密提供可用性。此外，还实现了一个基于 FPGA 的数字平台，以验证初始增强超混沌吸引子。此外，通过部署共存的超混沌序列，设计了基于 STM32 的图像加密算法，并通过了各种性能测试。这验证了超混沌序列在基于 STM32 的硬件实现图像加密算法中的可行性。
