Intrusion tolerant GRID in ad-hoc networks

Computational GRID on ad-hoc networks allows users to benefit from heterogeneous resources independently of their location. Access to those resources should be highly secured. This paper presents two contributions to define and manage trust for GRID applications in ad-hoc networks. First, we define a dynamic trust model that enables to dynamically assign trust levels to nodes according to their behavior in their cluster. Second, we use the proposed model to define the notion of tolerant GRID to intrusions targeting ad-hoc resources.
