The MyProxy service provides a certificate repository. It permits secure storage of long-term proxy certificates used to access grid services, thus enabling proxy certificate renewal for long-running jobs as well as delegation, i.e. the ability for services or cron jobs to act on behalf of a user when invoking grid services.
This service is crucial to the Grid as for security reasons, proxy certificates submitted to grid services often have a shorter lifetime than the jobs themselves and renewal is necessary so that long-running jobs don’t fail because of an expired proxy certificate.
The service uses the Globus MyProxy software.
