In a generic setting subsuming communication networks, resource sharing systems, and multi-agent communities, a client generates objects of various classes carrying class-dependent signatures, to which a server assigns class-dependent service quality. A Fake VIP attack consists in false declaration of a high class, with an awareness that detection of object signature at the server side is costly and so invoked reluctantly. We show that such attacks can be mitigated by a server-side double-blind repu-tation scheme. We offer a minimum-information framework for Fake VIP attacks and a stochastic analysis of a two-player Stackelberg game to find optimum attack and defense strategies, as well as to identify regions of operation where both the client and the server find the reputation scheme beneficial.
