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. Researchers at the State University of Pennsylvania proposed and experimentally demonstrated an “all-in-one” 8 × 8 array of robust, low-power, and bio-inspired crypto engines monolithically integrated with IoT edge sensors based on 2D memtransistors. Each engine comprises five 2D memtransistors to accomplish sensing and encoding functionalities. They showed that the ciphered information is secure from an eavesdropper with finite resources and access to deep neural networks. The 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…read more.
