Privacy Protection Mechanism in Grid Computing Environment

Many users consider their true identities as their privacy, and just wish to pay for the service without exposing their identities, which leads to the problem of the privacy protection in grid environment. The pseudonym management is already well understood in current internet. But up to now, there is no good solution in grid environment. In this paper, we explore whether the current pseudonym management in internet can be applied to grid environment or not, and provide a good solution to solve this issue. Through the analysis of both X.509 format certificates with entity information and the process of entity authentication, we present an approach of how to wrap the privacy information of grid users using alias name schema.
