硬件固有安全原语采用电子硬件中的实例特定的和过程引起的变化作为加密数据的源。在各种新兴技术中，忆阻器由于其潜在的随机操作而在这种安全应用中提供了独特的机会。在这里，我们表明，忆阻器的模拟调谐和非线性电导变化可以用来构建一个基本的构建块，用于实现弹性，密集，快速和节能的物理不可克隆功能。使用两个垂直集成的10 x 10金属氧化物忆阻交叉开关电路，我们实验证明了一个安全原语，提供了接近理想的50%的平均均匀性和扩散性，以及约1.5 +/-1%的最小误码率。器件电导的重新调整允许用相同的交叉开关电路实现几乎唯一的安全实例。
Hardware-intrinsic security primitives employ instance-specific and process-induced variations in electronic hardware as a source of cryptographic data. Among various emerging technologies, memristors offer unique opportunities in such security applications due to their underlying stochastic operation. Here we show that the analogue tuning and nonlinear conductance variations of memristors can be used to build a basic building block for implementing physically unclonable functions that are resilient, dense, fast and energy-efficient. Using two vertically integrated 10 x 10 metal-oxide memristive crossbar circuits, we experimentally demonstrate a security primitive that offers a near ideal 50% average uniformity and diffuseness, as well as a minimum bit error rate of around 1.5 +/- 1%. Readjustment of the conductances of the devices allows nearly unique security instances to be implemented with the same crossbar circuit.
