In order to achieve a reasonable evaluation of direct trust, this paper proposes a trust evaluation algorithm based on the domain, using the technique of constructing a hierarchical tree of trust evaluation subjectively. The algorithm adopts the rules of series and parallel operations in the D-S theory, acquires the results of the recommended trust problem of a single path by quadrature methods and...
In this paper, we propose a new IDPMS (In-Domain Protection and Management Scheme) to solve the multi-user problem and rights leak in the Digital Rights Management (DRM) systems. The content is divided to content objects to be delivered to the client devices without the need of being kept by the device. The proposed IDPMS defined a new DRM vector to replace the initial vector of the encrypt/decrypt...
Since Internet is one of the key technological aspects in an information society, Domain Management becomes crucial when trying to the spread of technologies within a country. The Spanish Authority has accordingly posed many efforts and resources towards improving the institutional support for both enterprises and individual citizens. The demand for domain services has increased exponentially in the...
IEC 61850 standard used Manufacturing Messages Specification (MMS) as its underlying communication protocol. The company standard that used in electrical system communication is not defined. It is necessary to research on the implementation of MMS protocol. In order to facilitate the implement of MMS, Petri net is used to model, analyze MMS protocol. This paper researches on the mapping rule of the...
The Barn project, a geospatial data grid prototype, provides a grid environment for applications of the nationwide geological survey data. Barn is developed based on the Globus Toolkit. Through Web portal, users can manage the grid resources, perform browsing, querying and analysis against the spatial data. According geospatial application nodes are organized into application domains. The node management...
Manufacturing message specification (MMS) is a set of communication protocols used in industrial control system. The petri nets model of domain management was established, and analysis of reachability and invariability was completed, which was used to validate the rationality and validity of the model. In addition, MMS communication service was implemented under the C/S mode through establishing MMS...
With the broad application of UNIX and its descendants in recent years, heterogeneous network environment is a must to maximize the enterprise's freedom of choice. However, because of different accounts formats and authentication mechanisms of various operating system (OS), heterogeneous network environment also increases difficulties for system management and security implementation. Facing the situation,...
Current Network Management paradigms are rigid and lack flexibility. This makes the task of managing a highly evolving and dynamic network difficult to cope with. This paper presents the results of our work on Agent technology as a new paradigm for developing Network Management applications. First, we present our agent architecture that is built in a way that allows the agent to acquire new capabilities...
