论文摘要
混乱使确定性物理系统中随机性的出现。因此，可以利用它在经典加密应用程序中强制性的真实随机数发生器（RNG）的概念。同时，纳米力学振荡器，在许多机上功能（例如传感）的核心中，表现为出色的候选者，以混乱地表现出来。由于纳米级出现了内在的机械非线性，因此这是可能的。在这里，我们提出了一个聚集纳米力学振荡器及其集成电容驱动的平台。使用电极引起的谐振力的调节，我们证明了混乱的动力学，并研究了它如何取决于系统的耗散。评估并讨论了由混沌时间痕迹产生的二进制序列的随机性，以便可以建立成功的随机数生成的通用参数。该演示利用了足够通用的概念，可以应用于下一代的纳米电子机械系统。
Chaos enables the emergence of randomness in deterministic physical systems. Therefore it can be exploited for the conception of true random number generators (RNG) mandatory in classical cryptography applications. Meanwhile, nanomechanical oscillators, at the core of many on-board functionalities such as sensing, reveal as excellent candidates to behave chaotically. This is made possible thanks to intrinsic mechanical nonlinearities emerging at the nanoscale. Here we present a platform gathering a nanomechanical oscillator and its integrated capacitive actuation. Using a modulation of the resonant force induced by the electrodes, we demonstrate chaotic dynamics and study how it depends on the dissipation of the system. The randomness of a binary sequence generated from a chaotic time trace is evaluated and discussed such that the generic parameters enabling successful random number generation can be established. This demonstration makes use of concepts which are sufficiently general to be applied to the next generation of nano-electro-optomechanical systems.
