Outline of Final Research Achievements

This theme examined methods to conceal and obfuscate programs for PLCs, computers designed for sequence control, by translating them into hard-wired circuits using FPGAs. Translation after applying an obfuscation method was studied and software infrastructure to obtain obfuscated circuits was developed. This theme also studied techniques for obfuscating and encrypting software on general purpose processors, in expectation of the case that only a part of a program was implemented by hardware and the rest was executed on a processor as software.
