| Outline of Final Research Achievements |
This research aims to develop a construction method for Malbolge, which is the most esoteric programming language, toward software protection by obfuscation. As a result, we succeeded to construct a system to convert C-subset language to Malbolge20, which is a word-length-extended Malbolge.
We first design the Malbolge20 language and construct an interpreter. Next, we developed a systematic method to generate malbolge20 codes from Low-level assembler of Malbolge, and implemented a translator. We further constructed a compiler that transforms C-subset language to Malbolge20.
