Security & trust enforcement in pervasive computing environment (STEP)

The propagation of ubiquitous computing is bringing in an environment, where multitudes of diverse entities interact with each other. It is widely acknowledged that traditional security measures do not scale well in environments which are epitomized by unforeseen circumstances, unexpected interactions, and unknown entities. We propose the trust based security architecture based on the human notion of trust as a mechanism to secure computing in ubiquitous environments.
