In this work, we present a methodology to design dynamical systems that display two-directional grid multiscroll hidden attractors. Self-excited attractors based on piecewise linear systems emerging from its equilibria in order to exhibit in one-directional (1D) and two-directional (2D) grid multiscroll hidden attractors. The particularity of this methodology is that the self-excited multiscroll attractor is separated into several double scroll self-excited attractors to allow the appearance of a hidden attractor. Next, the hidden attractor is used as the core of a cryptographic safe pseudo-random bit generator and statistical evidence is provided to ensure its convenience in cryptographic applications.

在这项工作中，我们提出了一种设计动态系统的方法，该系统显示双向网格多滚动隐藏吸引子。基于分段线性系统的自激吸引子从其平衡中出现，以便在单向 (1D) 和双向 (2D) 网格多滚动隐藏吸引子中展示。这种方法的特殊性是将自激多涡旋吸引子分成几个双涡旋自激吸引子，以允许隐藏吸引子的出现。接下来，隐藏吸引子被用作密码安全伪随机位发生器的核心，并提供统计证据以确保其在密码应用中的便利性。
