The Computational Grid concept allows for large-scale resource sharing. The implementation of Grid environments relies on the existence of a communications infrastructure and efficient resource management. Access control and secure communication are also required. Architectures to support Computational Grids can be developed in a variety of ways. This work presents an approach to create a Grid ...

The event-condition-action paradigm (also known as triggers or rules) gives a database “active” capabilities – the ability to react automatically to changes in the database or in the environment. One potential use of this technology is in the area of multilevel secure (MLS) data processing, such as, military, where the subjects and objects are classified into different security levels and manda...

This paper presents the designed concept to improve the public key infrastructure deployability in the mobile adhoc networks routed by B.A.T.M.A.N. Advanced. We have extended the B.A.T.M.A.N. Advanced routing protocol with authentication and authorization of routing updates based on X.509 certificates. Furthermore we have determined several levels of node’s trustworthiness and two levels of int...
