1.2.3.6 CROWN CredMan

This is used to manage user credentials. Through the agent certii cate
issue, the identii ed subjects can be managed, especially when the job is
submitted from a Web portal or in mobile networks.

1.2.3.7 CROWN CredFed

This contains a plug-in for the node server and a credential mapping
service. It can be used to map credentials from different security infra-
structures (such as PKI and Kerberos) to enable identity mapping between
two security domains. Administrators can modify the mapping policy to
control the behavior of CredFed.

1.2.3.8 CROWN ATN

This contains a plug-in for the node server and a set of generic services. The
ATN establishes the trust relationship between strangers on the Internet,
protecting the privacy (e.g., the information on attributes-based certii cates
and the negotiation policies) of both sides. It provides a security decision
and trust management mechanism for an open network environment.

1.2.3.9 CROWN Portal and Rich Client Framework

These two tools provide a unii ed user interface to the service grid to
support the job parameter coni guration, job submitting, JSDL generating,
and result demonstration. The CROWN Portal provides a Web-based
interaction model for the applications, and the Rich Client Framework
provides a Java-based application framework for applications that have
extensive visualization and interaction demands (such as complex visu-
alization). The framework can be customized according to the application
scenario to speed up the application development.

1.2.3.10 CROWN Designer

This is a grid service developing and deploying tool based on the Eclipse
platform. A set of wizards and dialogs provided make the development
and deployment of a grid service easier. By using the remote and hot
deploy features of the node server, the designer provides drag-and-drop
features to deploy the GAR i le. In the near future, more service orchestra-
tion tools will be integrated into the CROWN Designer.

1.2.3.11 CROWN Monitor

Th is is an Eclipse RCP-based client tool written i n Java. It is used to retrieve,
store, and analyze events/information from different grid entities, and to
