Keynote title: Security and Trust in a Ubiquitous Computing World

Abstract: Security issues have been at the forefront with the dramatic developments in technologies and their application in businesses affecting every part of our society. They have become critically important when it comes to the provision of distributed services to enterprises and users over wired, wireless and mobile networks. Though trust has always been a foundational stone of security, the ubiquitous nature of computing and the use of information from various sources in making vital decisions have increased the need to consider trust issues more thoroughly and systematically. This is the case in a wide range of technologies whether it is cloud based services or social networking applications or mobile ad hoc or sensor networks.

In this talk, we will first take a look at the notion of trust in the security world and see how trust issues arise in current ubiquitous computing systems context. We will then consider how state of a system is used in the formulation of trust. We will explore how social aspects of trust based on reputation and experience can be used to augment the hard state based trust. Such a hybrid approach can help to improve the detection of malicious entities which in turn can enhance the quality of secure decision making. We will demonstrate this trust enhanced security approach using some example systems that we have been developing over the recent years in distributed system services and mobile ad hoc networks.

He also headed the Technical Security Strategy Initiative at HP under the Senior Vice President of HP. Earlier, he was Research Manager of Data Security Lab at British Telecom Research Labs. U.K., Research Fellow and Lecturer in Computer Science at Plymouth and Reading Universities.

Vijay was an inaugural Board Member of International Advisors of TCPA, USA, (originally formed by HP, Microsoft, Intel, Sun and Compaq). TCPA security specification is currently being used by numerous companies (over 200) in their products. In 2002, he has been recognized as one of the leading authorities in Security in the world and appointed to the Trustworthy Computing Advisory Board (Microsoft, USA). Vijay is also a member of the SAP (Germany) Security Advisory Board. Vijay is a member of the Australian Government's Peak Security Advisory Group for the Minister of Broadband, Communications and Digital Economy, Australia. He is a member of the ARC College of Experts in Engineering, Mathematics and Informatics. He has been the Technical Board Director of Computer Science at Australian Computer Society, and Chair of the National Taskforce on E-Security. Vijay has been on the Editorial Board of several journals including the IEEE Transactions in Dependable and Secure Computing, the ACM Transactions on Information Systems Security, Springer International Journal of Information Security and IEEE Security and Privacy. Vijay has had several invited and visiting positions at different institutions in the world, including Senior Research Scientist at Isaac Newton Institute at Cambridge University (UK), at Microsoft Research Labs Cambridge UK and Redmond, USA, at Fujitsu Research Labs, invited Professor at INRIA Research Labs. France, Edinburgh University, Institute of Mathematical Sciences at National University of Singapore, The Chinese Academy of Sciences, and the Indian Inst. of Technology as well as Fellow at British Telecom Research Labs., UK.

Vijay has published over 320 papers in International Journals and Conferences, has co-authored and edited 9 books and holds 3 patents. His research work over the years has contributed to the development of several successful secure commercial systems and have generated many hundreds of millions of dollars of revenue. His current areas of research interest include Web Services Security, Secure Distributed Applications, Trusted Computing, Wireless and Mobile Security, Cloud Computing and Security, Internet Security, Cyber Security Attacks, Secure Social Computing, Security Policies and Architectures.
