A Mathematical Approach towards Trust Based Security in Pervasive Computing Environment

Abstract

In ubiquitous computing traditional security mechanism is difficult to realize, as users do not have prior knowledge of each other and the availability of a trusted third party cannot be relied upon. Since trust is used as an elementary channel of interaction in a human society, a security model based on the real world characteristics of trust can provide the internal security before taking action, despite uncertainty and inadequate information in ubiquitous computing environment. We propose the trust based security architecture based on the human notion of trust as a mechanism to secure computing in ubiquitous environment.
