As an important aspect of grid security, access control model gets more and more attention. Entities in virtual organizations (VOs) must establish a dynamic, secure and cooperative...
Abstract. We apply the theory of asynchronous automata to the synthesis problem of closed distributed systems. We use safe asynchronous automata as implementation model, and charac...
Common to Grid services, Web Services, software agents and software components is that they are independently built and provide services aimed for composition. A key issue is wheth...
An instance-oriented security mechanism is proposed to deal with security threats in building a general-purpose mobile agent middleware in Grid environment. The proposed solution i...
Although there have been several attempts to create grid systems, there is no clear definition for grids. In this paper, a formal approach is presented for defining elementary func...
