在物联网（IoT）的新兴时代，无处不在的传感器不断收集，消费，存储和传输大量信息，这些信息越来越容易被盗和滥用。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，这使得它们很难被物联网边缘传感器采用，这些传感器在有限的硬件资源和低能耗预算下运行。在这里，我们提出并通过实验演示了一个“一体化”的8 × 8阵列，该阵列由基于二维（2D）记忆晶体管的物联网边缘传感器单片集成的鲁棒、低功耗和生物启发的加密引擎组成。每个引擎包括五个2D记忆晶体管以实现感测和编码功能。的窃听信息被证明是安全的，从一个窃听者与有限的资源和访问深度神经网络。我们的硬件平台由总共320个完全集成的单层基于MoS2的记忆晶体管组成，消耗数百皮焦耳的能量，并提供近传感器的安全性。物联网（IoT）传感器可以收集、存储和传输大量信息，这需要采取有效的安全措施。在这里，作者报告了基于光敏和可编程2D记忆晶体管的低功耗边缘传感器的实现，集成了传感，存储和加密功能。
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. Internet of things (IoT) sensors can collect, store and communicate large volumes of information, which require effective security measures. Here, the authors report the realization of low-power edge sensors based on photosensitive and programmable 2D memtransistors, integrating sensing, storage and encryption functionalities.
