SECURITY OF SMART OBJECTS IN IoT

Abstract

The internet of things involves people interacting with the technological environment based on what we considered things as “smart objects” allowing sharing of information through communication on internet. As the concept of IoT and its application is growing rapidly, the security aspect becomes very important and critical which has to be looked upon with severe importance. Security is needed anywhere where computation happens. Since the IoT allows various objects or devices to connect to internet forming a network communicating with each other or with the human user, the usage of large scale of objects on the network and the heterogeneity of those objects plays as a major security issue. Therefore, we focus on the security and privacy aspects regarding the issues, the various challenges that are being faced, and try to study the feasible solutions for the above security challenges, and also using few applications as examples. According to the observations made, it is found that there are two main approaches as referred in the existing papers which are systemic and cognitive approach. Due to the large number of interactions between things, a systemic and cognitive approach and decentralized approach seems to be an appropriate choice for IoT security.
