A request digitally signed by a requestor is received. The digitally signed request contains the electronic document digitally signed by the grantor. The electronic document also contains a grantor certified reference, a requestor certified reference, and access control rules for the requestor. The request is validated using the requestor certified reference and the access control rules for the requestor.
