Hardware Security In article number 2400661, Akshay Wali, Harikrishnan Ravichandran, and Saptarshi Das present a novel hardware security authentication system that employs programmable integrated circuits (ICs) crafted from atomically thin monolayers of molybdenum disulfide (MoS2), a two-dimensional material. It capitalizes on the inherent randomness of charge trapping and de-trapping in 2D memtransistors to generate cryptographic keys. Additionally, it utilizes the properties of a NOR gate to establish a secure one-way hash function.
