Abstract
One embodiment of the present invention provides a system that authenticates requests between tasks in an operating system. During operation, a first task prepares a request to perform an operation in a second task. In doing so, the first task attaches a credential to the request, and then a trusted entity transfers the request and the credential to the second task. Next, the second task determines whether the credential is valid. If the credential is valid, the second task determines from the credential whether the first task is authorized to request the operation, and, if so, proceeds to perform the operation.
