A Cipher Class Based on Golden S-Boxes for Creating Clone-Resistant Identities

摘要

Secret Unknown Cipher (SUC) concept was proposed as a promising technique to create clone-resistant electronic units as alternative to overcome the weaknesses of the traditional Physical Unclonable Functions (PUFs). A low-complexity real-field realization scenario for the proposed SUC concept is presented in this work. The key realization concept is making use of the so-called Golden S-Boxes as basic building blocks of block ciphers. According to the new proposed concept, the cipher creator called "GENIE" generates unknown ciphers with relatively low memory and time complexities. The target technology to accommodate the proposed self-created hard to predict SUCs is the non-volatile FPGA System on Chip (SoC) units converting them into clone-resistant entities.
