In the emerging era of the internet of things (IoT), ubiquitous sensors continuously collect, consume, store, and communicate a huge volume of information which is becoming increasingly vulnerable to theft and misuse. Modern software cryptosystems require extensive computational infrastructure for implementing ciphering algorithms, making them difficult to be adopted by IoT edge sensors that operate with limited hardware resources and at low energy budgets. Here we propose and experimentally demonstrate an “all-in-one” 8 × 8 array of robust, low-power, and bio-inspired crypto engines monolithically integrated with IoT edge sensors based on two-dimensional (2D) memtransistors. Each engine comprises five 2D memtransistors to accomplish sensing and encoding functionalities. The ciphered information is shown to be secure from an eavesdropper with finite resources and access to deep neural networks. Our hardware platform consists of a total of 320 fully integrated monolayer MoS₂-based memtransistors and consumes energy in the range of hundreds of picojoules and offers near-sensor security.

在物联网 (IoT) 的新兴时代，无处不在的传感器不断收集、消费、存储和传递大量信息，这些信息变得越来越容易被盗窃和滥用。现代软件密码系统​​需要广泛的计算基础设施来实现加密算法，这使得它们难以被以有限硬件资源和低能量预算运行的物联网边缘传感器采用。在这里，我们提出并通过实验证明了“一体式”8 × 8 阵列稳健、低功耗和仿生加密引擎，与基于二维 (2D) 存储器晶体管的物联网边缘传感器单片集成。每个引擎包含五个 2D 内存晶体管来完成传感和编码功能。加密信息被证明是安全的，可以防止资源有限的窃听者访问深度神经网络。我们的硬件平台由总共 320 个完全集成的基于 MoS ₂的单层薄膜晶体管组成，消耗的能量在数百皮焦耳范围内，并提供近传感器安全性。
