The rapid development and increasing complexity of computer systems and communication networks coupled with the proliferation of services and applications in both Internet-based and ad-hoc based environments have brought network and system security issues to the fore. We have been witnessing ever-increasing cyberattacks on the network and system leading to tarnished confidence and trusts in the use of networked distributed systems. As a result, there is an increasing demand for development of new trust, security and privacy approaches to guarantee the privacy, integrity, and availability of resources in networked distributed systems.
