While most recent protection techniques rely on the security of a secret key, this work presents a new approach: hardware FSM honeypots. These honeypots lead the RE tools to a wrong but, for the tools, very attractive FSM, while making the original FSM less attractive. The results show that state-of-the-art RE methods favor the highly attractive honeypot as FSM candidate or do no longer detect the correct, original FSM.enfalseIC trustnetlist reverse engineeringstate machine obfuscationhoneypot600 Technik, Medizin, angewandte Wissenschaftenconference paper
