Data and code integrity in Grid environments
Rachel Akimana, Olivier Markowitch · 2006
Abstract:- In a large distributed system such as the Grid, ensuring data integrity is of particular importance. Since in a same network honest users and possible malicious entities live together, the risks of unauthorized alterations of data and information cannot be ignored. This concern on data integrity has two faces. On the one hand, insurance has to be given that data has not been altered by unauthorized hands. This is called integrity of passive data. On the other hand, users may want to have the guarantee that the jobs they submit on the Grid are executed in the right way with the proper input data, and result on reliable output data. This second flavor of integrity is called integrity of active data. In this paper, we consider these integrity concerns, identify the needs when considering privacy aspects of passive data and a Grid’s adapted framework for integrity of active data. Key-Words:- Grid security, integrity, privacy 1
