Abstract
A system and method for controlling the use by caller objects to a restricted method of a resource object in an object-oriented computing environment are provided in accordance with one embodiment of the invention. The method is based on associating an access-token with a caller object which is to be allowed to access the restricted method and sharing this access-token with the resource object. When subsequent calls to the restricted method are made by a caller object, access is made contingent on the caller object providing the access-token as part of the call procedure. Where no access-token is provided, or an invalid access-token is provided, access to the method is denied or restricted. The method provides protection against innocently made wrong calls to a restricted method by a caller object, for example due to coding errors. The method also provides protection against maliciously made calls to a restricted method by caller objects that should not have access to it.
