Tamper-resistant software (TRS) consists of two functional components: tamper detection and tamper response. Although both are equally critical to the e\ufb00ectiveness of a TRS system, past research has focused primarily on the former, while giving little thought to the latter. Not surprisingly, many successful breaks of commercial TRS systems found their \ufb01rst breaches at the relatively na\u0131ve tamper-response modules. In this paper, we describe a novel tamper-response system that evades hacker detection by introducing delayed, probabilistic failures in a program. This is accomplished by corrupting the program\u2019s internal state at well-chosen locations. Our tamper-response system smoothly blends in with the program and leaves no noticeable traces behind, making it very di\ufb03cult for a hacker to detect its existence. The paper also presents empirical results to demonstrate the e\ufb03cacy of our system.<\/p>\n","protected":false},"excerpt":{"rendered":"
