title = "A dynamic approach for characterizing collusion in desktop grids",
abstract = "By exploiting idle time on volunteer machines, desktop grids provide a way to execute large sets of tasks with negligible maintenance and low cost. Although desktop grids are attractive for cost-conscious projects, relying on external resources may compromise the correctness of application execution due to the well- known unreliability of nodes. In this paper, we consider the most challenging threat model: organized groups of cheaters that may collude to produce incorrect results. We propose two on-line algorithms for detecting collusion and characterizing the participant behaviors. Using several real-life traces, we show that our approach is accurate and efficient in identifying collusion and in estimating group behavior.",
