Outline of Final Research Achievements

I have implemented a PUF-KEY circuit on a Kintex-7 FPGA that consists of a physically unclonable function (PUF), fuzzy extractor and AES circuits. A fuzzy extractor generates a cryptographic key from noisy PUF outputs by applying an error correcting code. In this study, I used (255, 239) Reed-Solomon (RS) codes for the fuzzy extractor. For the development of an RS encoder and decoder, I used Matlab HDL Coder, which is one of the popular high-level synthesis tools available. In this study, I show the speed and area performance of the PUF-KEY circuit. I also experimentally show the effectiveness of the PUF-KEY circuits by using three SASEBO-G3 FPGA boards. I confirmed that each PUF-KEY circuit on the boards generates a unique key, and then the same key is regenerated from the same PUF.
