It is a Globus Toolkit component that provides a number of useful services for grids, including mutual authentication and single sign-on. However, manipulating grid certificates using the Globus Toolkit 3.0 (GT3) in Windows environments is an awkward situation. It usually requires that system administrators or users install GT3 on Linux systems in order to use the command line scripts to generate certificates. Then they must move those certificates to their Windows systems. This article demonstrates an easier alternative, provided by the Java CoG Kit: using a Java class to create and sign grid proxies and certificates.

    Grid Security Infrastructure (GSI) is based on proven standards such as public key encryption, X.509 certificates, and the Secure Sockets Layer (SSL). Extensions to these standards have been added for single sign-on and delegation.

    One of the main concepts in GSI authentication is certificates. Every grid service and user is identified by means of a certificate, which contains information used to authenticate and identify that user or service.
