| Abstract(in English) | With the developments and spreads of computers, the number of digital media that we treat on computers has been increasing. The number of threats that try to violate digital rights of these media is also increasing. We must protect these media properly from the threats. In this paper, we discuss software protection methods. It is important to hide protection mechanisms from adversaries. One way to achieve the purpose is to make software difficult to analyze. Software metamorphosing at runtime increases the amounts of software that the adversaries have to analyze, and it also increases the costs of analyses consequently. The existing methods require network connections to update software. In this paper, we propose a software metamorphosing method that works offline. Our method inserts redundant instructions to metamorphose software. In general, protection mechanisms increase the execution costs of software. Our method is able to control these costs via the amounts of redundant instructions and the frequencies of metamorphosing. We used SPEC 2000 benchmarks to verify the controllability of our method. These experiments show the feasibility of our offline metamorphosing method. Since the analyses of software are the starting points of illegal activities, our method improves software protections. |
