Security and Privacy Framework for Ubiquitous Computing Applications

In traditional wired network (which is typically a Client-Server architecture or Infrastructure mode), Security policies are maintained and managed in a centralized static server to address Integrity, Availability, Confidentiality, Authentication and Non-Repudiation etc issues. With the rapid advancement in the wireless networking and mobile technology, devices have become tiny and miniature and they were able to interact with one another seamlessly in day-to-day lives. In such a Ubiquitous world, new security issues like context-aware, location-aware trust management, privacy comes into picture. Thereby, Security in Ubiquitous computing is highly dynamic and distributed in nature which changes with any change in the context, location, time, entity etc. So, the existing traditional security mechanisms won't suffice for the new needs.

Centre is working in this area to develop a Comprehensive Security, Privacy & Trust Management framework for Ubiquitous Computing Environment (titled U-Visvaas) which addresses the security requirements of enterprise and peer-to-peer applications through Context Role Based Access Control as well as Trust Negotiation Models respectively.

• Supports both Ad-hoc and Infrastructure mode
• Non-Intrusive and Transparent
• Context Sensitive and Adaptable with the situational information
• Different levels of security (based on policies, environmental situation and available resources)
• Dynamic Authentication policies based on trust  or stack based Pluggable Authentication Module
• Flexible Authorization policies incorporating context
• Privacy policies
