  5. Solution: “MyProxy” • Myproxy allows you to store a long-lived proxy in a “MyProxy repository” and derive a proxy certificate when needed. • Allows you to: • Interact with a grid from many machines • And you realise that you must NOT, EVER leave your certificate where anyone can find and use it. • Use a portal, and delegate to the portal the right to act on your behalf (by logging in to an account that can make a proxy certificate for you) • Run jobs that might last longer than the lifetime of a short-lived proxy Induction to Grid Computing and the National Grid Service, Oxford University Computing Services, 5th-6th July 2005
