Trust enhanced security in networked systems

The recent decades have witnessed dramatic developments in information and communication technologies, and the Internet is transforming the way we work and live. Along with the phenomenal growth in technology and technology enabled information economy has been a growth in technology related crimes. Security, trust and privacy on the Internet are causing major concerns and are no longer at socially acceptable levels by almost any reasonable standards. From consumer threats (such as identity theft) to enterprise threats (e.g. loss of personally identifiable information data) to government threats (e.g. information warfare), there is little doubt that sophisticated adversaries are causing malicious effects. In this talk, we will consider the technical challenges involved in the development of secure and trustworthy networked systems and infrastructures. We will address aspects such as the notions of trust in the security technology world, how does one user trust another user or a service provider over the Internet and design choices for developing trustworthy systems and networks. We will introduce the notion of "trust enhanced security" and discuss how such an approach can be used to enhance security decisions in distributed systems and mobile ad hoc networks.
