Executive Summary

With the growth of wireless networks and mobile devices, the authors are moving closer towards an era of Cyber Physical Systems (CPSs). Such systems have the potential to benefit numerous applications in areas as diverse as military, financial, and health care. However, security issues must be addressed before CPSs can be widely deployed. The problem is serious because CPSs involve interactions between a large number of entities that can span different organizational boundaries. Unlike traditional applications, these applications do not usually have well-defined security perimeters and are dynamic in nature.
