Overview The Internet Of Things (IOT) System Security,Applications,Architecture And Business Models Ahmad Firdausi Department of Electrical Engineering Universitas Mercu Buana Jakarta, Indonesia Ahmad.firdausi@ymail.com Abstract— The Internet of Things (IoT) brings together a mul-titude of technologies, with a vision of creating an interconnected world.This paper provides an overview of the Internet of Things (IoT) with emphasis on enabling system security,architecture,business models and application issues. The IoT is enabled by the latest developments in RFID, smart sensors. The basic premise is to have smart sensors collaborate directly without human involvement to deliver a new class of applications. The current revolution in Internet, mobile and machine-to-machine (M2M) technologies can be seen as the first phase of the IoT. In the coming years, the IoT is expected to bridge diverse technologies to enable new applications by connecting physical objects together in support of intelligent decision making. We survey the four most dominant IoT architectures and analyze their security components with respect to the requirements. Our analysis shows a mediocre coverage of security requirements. Keywords—IoT,Internet of Things,RFID I. INTRODUCTION Internet of Things (IoT) is a new revolution of the Internet. It makes Objects themselves recognizable, obtain intelligence, communicate information about themselves and they can access information that has been aggregated by other things. The Internet of Things allows people and things to be connected Anytime, Anyplace, with Anything and Anyone, ideally using Any path/network and Any service,This implies addressing elements such as Convergence, Content, Collections, Computing, Communication, and Connectivity.[1] A growing number of physical objects are being connected to the Internet at an unprecedented rate realizing the idea transportation, healthcare, industrial automation, and emergency response to natural and man-made disasters where human decision making is difficult. The IoT enables physical objects to see, hear, think and perform jobs by having them ―talk‖ together, to share information and to coordinate decisions. The IoT transforms these objects from being traditional to smart by exploiting its underlying technologies such as ubiquitous and pervasive computing, embedded devices, communication technologies, sensor networks, Internet protocols and applications. Smart objects along with their supposed tasks constitute domain specific applications (vertical markets) while ubiquitous computing and analytical services form application domain independent services (horizontal markets). Fig. 1 illustrates the overall concept of the IoT in which every domain specific application is interacting with domain independent services, whereas in each domain sensors and actuators communicate directly with each other. Over time, the IoT is expected to have significant home and business applications, to contribute to the quality of life and to grow the world‗s economy. For example, smart - homes will enable their residents to automatically open their garage when reaching home, prepare their coffee, control climate control systems, TVs and other appliances. In order to realize this potential growth, emerging technologies and innovations, and service applications need to grow proportionally to match market demands and customer needs. Further more, devices need to be developed to fit customer requirements in terms of availability anywhere and anytime. Also, new protocols are
