The private part of a key pair. Depending on the type of certificate the key corresponds to it may typically be found in $HOME/.globus/userkey.pem (for user certificates), /etc/grid-security/hostkey.pem (for host certificates) or /etc/grid-security/<service>/<service>key.pem (for service certificates).

For more information on possible private key locations see [Credentials in the Pre-WS Authentication & Authorization Developer's Guide ("Environmental Variables" section)].

A short lived certificate issued using a EEC. A proxy certificate typically has the same effective subject as the EEC that issued it and can thus be used in its place. GSI uses proxy certificates for single sign on and delegation of rights to other entities.

For more information about types of proxy certificates and their compatibility in different versions of GT, see http://dev.globus.org/wiki/Security/ProxyCertTypes.

The combination of a proxy certificate and its corresponding private key. GSI typically stores proxy credentials in /tmp/x509up_u<uid> , where <uid> is the user id of the proxy owner.

Term used to describe a job scheduler mechanism to which GRAM interfaces. It is a networked system for submitting, controlling, and monitoring the workload of batch jobs in one or more computers. The jobs or tasks are scheduled for execution at a time chosen by the subsystem according to an available policy and availability of resources. Popular job schedulers include Portable Batch System (PBS), Platform LSF, and IBM LoadLeveler.

The combination of a service certificate and its corresponding private key.

Uses transport-level security (TLS) mechanisms.

A EEC belonging to a user. When using GSI, this certificate is typically stored in $HOME/.globus/usercert.pem. For more information on possible user certificate locations, see [Credentials in the Pre-WS A&A Developer's Guide ("Environmental Variables" section)].
