A Purpose-Oriented Access Control Model
In distributed applications, multiple objects cooperate to achieve some objectives. Each object is manipulated through an operation supported by the object and then the operation may further invoke operations of other objects, i.e. nested operations. Purpose-oriented access rules indicate what operation in each object can invoke operations of other objects. Information flow among the objects oc...
متن کاملReprogramming Matter, Life, and Purpose
Reprogramming matter may sound far-fetched, but we have been doing it with increasing power and staggering efficiency for at least 60 years, and for centuries we have been paving the way toward the ultimate reprogrammed fate of the universe, the vessel of all programs. How will we be doing it in 60 years’ time and how will it impact life and the purpose both of machines and of humans? 1 Informa...
متن کاملA Purpose-Oriented Access Control Model for Object-Based Systems
Distributed applications are modeled in an object-based model like CORBA [1]. Here, the system is a collection of objects. The objects are manipulated only through operations supported by themselves. The purpose-oriented model [2] is proposed where an access rule shows for what each subject s manipulates an object o by an operation t of o so as to keep the information flow legal. The purpose of...
متن کاملInformation Flow in a Purpose-Oriented Access Control Model
In distributed applications, a group of multiple objects are cooperating to achieve some objectives. An object is modeled as a pair of data structure and operations. Each object is manipulated through an operation supported by the object and then the operation may further invoke operations of other objects, i.e. nested operations. The purpose-oriented access rules indicate what operation in eac...
