Abstract: With the appearance and application of Grid technology, the security problem becomes the emphasis of grid research. Globus Security Infrastructure (a security component in Globus) provides us a solution in single authentication domain. Currently, how to resolve the authentication across domains is the most important security problem in the large-scale grid. In this paper, authentication mechanism of GSI is introduced firstly. Then, the multi-domain authentication method based on mapping is proposed. Grid security performance can be improved by this new mechanism. High-level implementation of this new mechanism is shown in detailed at the end of the paper.
