Abstract\nSoftware control is a critical issue in cyber-physical systems (CPS); if the expected behavior of the software embedded\nin a single device of a CPS cannot be enforced then the behavior of the whole CPS may be in jeopardy. Thus, CPS\nstakeholders like having some level of control over the embedded software. Third-party demands to control the\nsoftware, however, conflict with the intellectual property protection demanded by software developers, since some\nlevel of detail about the software at hand would have to be disclosed. In the present paper, we discuss the issue of\ncontrolling the software embedded in CPS devices and address the problem of how to achieve an increased level of\nsoftware control without compromising the protection of intellectual property. We propose a two-party\nfingerprinting scheme that allows for attribution of responsibility in the case of intellectual property leaks. Our\nfingerprinting scheme is such that neither party may obtain an advantage over the other by misbehaving,\nmisrepresenting or by prematurely aborting the protocol, therefore providing a fair means to resolve disputes
