| Abstract |
Physically unclonable function (PUF) has been spotlighted for high level of hardware security. However, due to process complexity and high fabrication cost, implementation of the PUF is difficult and limited. In this work, we demonstrates novel fabrication methodology and security device for the PUF. All of fabrication processing is based on solution based, and does not require any use of deposition, etching, and even lithography. Tens of PUF dies are fabricated, then binary codes based on measured geometric size of MoS2 flakes, are generated. After assembling of several dies for the PUF chip, Hamming distance and Hamming weight are analyzed to verify the hardware security. Considering uniqueness, uniformity, unclonability, robustness, and cost effectiveness, this kind of the PUFs seems suitable for mass production. |
