Privacy and Security Challenges in Internet of Things

Abstract

Internet of Things (IoT) envisions as a global network, connecting any objects around us, ranging from home appliances, wearable things to military applications. With IoT infrastructure, physical objects such as wearable objects, television, refrigerator, smart phones, supply-chain items and any objects across the globe would get connected using the Internet. Sensing, radio waves, mobile technology, embedded systems and Internet technology are promising actors which play significant roles in IoT infrastructure. Security and privacy issues in IoT scenarios would be much more challenging than what is been used in the conventional wireless scenarios. In particular, the constrained environments require lightweight primitives, secure design and effective integration into other environments in order to see IoT in its desired shape. In this paper, we discuss security and privacy challenges in IoT scenarios and applications with special emphasis on resource-constrained environments’ security objectives and privacy requirement. We provide different perspectives of IoT, discuss about important driving forces of IoT, and propose a generic construction of secure protocol suitable for constrained environments with respect to IoT scenarios and applications.
