Trustworthy Wireless Networks : Issues and Applications

Wireless networks are susceptible to various attacks due to their open nature of operations. Existing security mechanisms and systems are rarely robust under attacks, misopera tion and internal faults. Most of the solutions are targeted to specific attacks and also works after detecting considerable damage and provides little protection if one or more components are compromised. These approaches are not sufficient for holistic and systemic security. In this paper we analyse a more systematic security approach by exploiting the fundamenta l relationships among the network components. We explore a concept called trust worthy network where nodes establishe s relationships among themselves based on the mutual observa tions and interactions. These relationships will help to derive t he level of security and trust to be possessed on the nodes and the message received from the nodes. We analyse in detail the var ious issues in constructing the trustworthy networks, impact ofvarious network dynamics on the trust relationships and the applications of trust worthiness in assessing the information quality, t o evict the misbehaving nodes and to provide other related security services.
