2、dely distributed computation resources, storage resources, networkresources, software resources and information resources etc. Grid technologies have extensiveperspective and development scope, but researches concerning

3、it are still on the first step. There aremany key technologies which need to be solved. On one hand, the powerful functions of Gridtechnologies can bring great convenience to scientific researches，on the other hand, much

4、 attentionmust be given to the security of the grid while using the fast and convenient functions and services.Grid security is not only the first defense line, but also the most important defense line, so theauthenticat

5、ion technology receives the attention generally. Existing Grid security certificate modelsinclude: centralized CA (Certificate Authority) model, mufti-CA model and crossed certificatemodel. But these models have various

6、defects. While using centralized CA model or mufti CAmodel, managing certificates will be very complicated and the amount of data and update amountsare great by means of adopting general management mode of the centraliz

7、ed model. When adoptingcrossed certificate model, the selection of the path will arises.This thesis researches and designs a certificate model based on X.509 and Kerberos. In thismodel, terminal user certificate's pr
