    Ubiquitous object categorization and identity
    (2006) Kulkarni, U.P.; Vadavi, J.V.; Joshi, S.M.; Chandra Sekaran, K.C.; Yardi, A.R.
    Ubiquitous computing technology provides an environment where users expect to access resources and services anytime and anywhere. Everyday objects communicate with each other and also with the Internet objects available today. People have an increasing desire for such ubiquitous access to information, anywhere, anyplace, and anytime. As ubicomp occurs everywhere, there may be a very large number of users/objects interacting with each other simultaneously in future. This necessitates the question of how to uniquely provide identity to infinitely growing objects and standard towards the uniformity of the data being exchanged by the various objects. The serious security risks and problems arise because resources can now be accessed by almost anyone with a mobile device in such an open model. In this paper, author proposes the way of providing uniqueness in scalable object identity, object categorization and standard in data being exchanged by various ubicomp compliant objects and explore the security issue in ubiquitous computing with a focus on authentication. © 2006 IEEE.

    Distributed multi level security token based authentication for ubiquitous objects -DMSA
    (2006) Kulkarni, U.P.; Vadavi, J.V.; Joshi, S.M.; Chandra Sekaran, K.C.; Yardi, A.R.
    Ubiquitous computing technology provides an environment where users expect to access resources and services anytime and anywhere. The serious security risks and problems arise because resources can now be accessed by almost anyone with a mobile device in such an open model. This paper explores security in ubiquitous computing with focus on authentication. We propose a new model, which uses distributed hierarchical tree based approach for authenticating ubiquitous objects which overcomes the problems associated with centralized source of information. © 2006 IEEE.
