Novel Security Model for Pervasive Systems

As portable devices have become a part of our everyday life, more people are unknowingly participating in a pervasive computing environment. People might engage in many computational devices simultaneously without even the awareness of their existence. The idea of pervasive computing is that almost every device we see today will be capable of communication and function in collaboration with one another in the near future. Due to lack of a fixed infrastructure for authentication and authorization, devices in pervasive computing are more susceptible to malicious snoopers. In this paper, we cover different pervasive computing-based projects that have adopted pervasive middleware as an integral part of the security enforcement in their projects. We then move on to identify security requirements especially inherent to pervasive computing which makes it a smart security system. Finally, a security model for pervasive system is proposed that compose the required pervasive security functions to be smart.
