In computer security, an Authorization Certificate (also known as Attribute Certificate) is a digital document that describes a written permisson from the issuer
to use a service or a resource that the issuer controls or has access to use.
The permission can be delegated.
Please see SPKI/SDSI Certificate Documention (http://theworld.com/~cme/html/spki.html) for an example.
This solution prevents the service or resource host from having to use large access control lists.
It is similar to the idea of capabilities: store the permission (or permissions) with a protected pointer to the object but not with the object itself.
