Abstract(in English)	Attempts of illegal software usages have been increasing. It is an important problem to protect software from these attempts. In order to protect software, we complicate the structures of software and/or make software tamper-resistant. We achieve protection mechanisms combining these two methods properly. In this paper, we focus on the obfuscation that tries to complicate the structures of software. Traditional obfuscation methods request computational costs that depend mostly on the methods. On the other hand, our method requests the costs that software determines. We show that we can easily control the costs of the method to adapt situations. Generally, the levels of the protections imply the costs. Consequently, we can control the levels of the protections.
