Abstract

Grid computing environments with public resources are used to process large problems taking advantage of many personal computers connected to the Internet. Some extra security services are required in this kind of environment to improve the quality of the results obtained. This document presents a method, which is based on task replication, to verify the correctness of the results given by the personal computers.
