CMM :Credential Migration Management system based on trusted computing in CGSP

摘要

In grid computing environment,grid users often identity.But the original user may be under the risk of information leakage and identity abused for sending his credential to remote computing environment.Existing grid security practice has few means to enforce the security of credential delivery.Trusted Computing (TC) technology can be added to grid computing environment to enhance the grid security.With TC using an essential in-platform (trusted)third party,Trusted Platform Module (TPM),we can use TC to protect the user credential.In this paper we present credential migration management (CMM) system,which is a part of Daonity project,to manifest migrating credential in security between different computers with TPM.
