Abstract

In this paper we address the problem of granting the correctness of Grid computations. We introduce a Grid Integrity Validation Scheme (GIVS) that may reveal the presence of malicious hosts by statistical sampling of computations results. Performance overheads of GIVS strategies are evaluated using statistical models and simulation.
