SECURE MULTI-ENTITY ACCESS TO RESOURCES ON MOBILE TELEPHONES

摘要

Controlling access to a specific resource on a mobile telephone comprises the steps of (a) associating an identity with a permission state, in which an identity is a label applicable to one of several entities on whose behalf the resource could potentially be used and the permission state defines whether or not the resource can actually be used; and (b) allowing use of the resource solely to an entity or entities labelled with an identity associated with a permission state that does permit such use.
