| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Hardware obfuscation serves as a countermeasure against hardware reverse engineering. Yamada et al. employed the OLLVM software obfuscation tool in conjunction with the HLS tool LegUp to generate obfuscated hardware, although LegUp is no longer available for research. In this paper, we generated obfuscated hardware using the HLS tool Bambu from LLVM Intermediate Representation (IR) obfuscated by OLLVM. The proposed method is verified using CHStone benchmarks. Consequently, Bambu successfully generated fully functional circuits, whose average LUT usage is 58% larger than that of Yamada's method. | |
