Professor Vijay Varadharajan


The Internet and the web technologies are transforming the way we work and live. Fundamental to many of the technological and policy challenges in this technology enabled society and economy are the issues of trust. For instance, when an entity receives some information from another entity, questions arise as to how much trust is to be placed on the received information, how to evaluate the overall trust and how to incorporate the evaluated trust in the decision making systems. Such issues can indeed arise at many levels in computing, e.g. at a user level, at a service level (in a distributed service oriented architecture), at a network level between one network device and another (e.g. in a sensor network) or at a process level within a system. There is also the social dimension involving how different societies and cultures value and evaluate trust in their contexts. Recently we have been witnessing users, especially the younger generation placing a greater trust on the information available on the Internet applications such as Facebook and MySpace, when it comes to making online decisions. The notion of trust has been around for many decades, if not for centuries, in different disciplines such as psychology, philosophy, sociology as well as in technology. From a security technology point of view, trust has always been regarded as a foundational building block. In this talk, we will take a journey through the different notions of trust in secure computing technology world and their evolution from the operating systems context to distributed systems to trusted computing platforms and trusted online applications. We will look at the some of the challenges involved in developing trusted services and infrastructures, and their influence on growing the digital economy.


Vijay Varadharajan is Professor and Microsoft Chair in Innovation in Computing at Macquarie University (2001 – todate). (http://www.comp.mq.edu.au/research/inss/members/). He is also the Director of Information and Networked System Security (INSS) Research.

Before this he was Foundation Chair and Head of School of Computing and IT at University of Western Sydney. Previously, Vijay has headed Security Research worldwide based at HP Labs UK for several years. Before this, he was a Research Manager at British Telecom Research Labs. U.K. Before that, he was Research Fellow and Lecturer in Computer Science at Plymouth and Reading Universities. He did his Ph.D in Computer and Communication Security in the U.K at Exeter University and Plymouth Universities in U.K. sponsored by BT Research Labs (1981-84). He did his Electronic Engineering Hons Degree from Sussex University, UK (1978-1981). He has also done Executive Business Management Administration Education at INSEAD European Business School (Paris) (1992).

Vijay’s current research interests are distributed systems security (security in web services and service oriented architectures), network security (mobile ad hoc networks security, denial of service attacks, Internet security), mobile computing security (secure mobile agent based systems), trusted computing (trust models, trusted platforms), secure peer to peer computing and formal security models and analysis. Vijay has published more than 275 papers in International Journals and Conferences, has co-authored and edited 8 books on Information Technology, Security, Networks and Distributed Systems and holds 2 patents. His research work over the years has contributed to the development of several successful secure commercial systems. Vijay has had several invited and visiting positions at different institutions over the years including Microsoft Research Cambridge UK, INRIA Research Labs, France, Fujitsu Research Labs, Japan, Institute of Mathematical Sciences at National University of Singapore, Indian Inst. of Technology, British Telecom Research Labs., UK and the Chinese Academy of Sciences. Vijay was on the Board of International Advisors of TCPA, USA and is on the Trustworthy Computing Academic Advisory Board (Microsoft, USA). He is a member of the IT Security Advisory Group to the Ministry of Broadband, Communications and Digital Economy, Australian Government. He has also acted as an Expert for European Union and worked with the UK Dept. of Trade and Industry. He has been the Technical Board Director of Computer Science at Australian Computer Society. Vijay has been on the Editorial Board of several journals including the ACM Transactions on Information System Security, IEEE Transactions on Secure and Dependable Computing and the International Journal of Information Security, Springer.


This meeting was webcast live.

For the majority of the meetings that we broadcast, we keep a copy (for a limited period) and make it available from the event material page. This copy of the webcast is normally available the day after the meeting.
