Empowering the Security for Iot-Based Communications in Smart City

Internet of Things (IoT) is a new idea, where thephysical objects is connected with the network using electronic hardware, actuators, sensors, software etc. in order to convey the information effectively and control/operate entity from distance. This term is first introduced by Kevin Ashton in 1998. Now days, this thing is used immensely to make the services more efficient. It is the technology that basically converts the existing Internet infrastructure into a highly superior computing network, where the devices are indentified and connected with each other. The major impact of this technology is its numerous aspects in everyday life for both single user applications as well as applications for society. With its big network of several interconnected devices belongs to the various fields in turns make a great risk related to its security. Several worldwide researchers are working on it to improve the secured services. Though, it remain has few challenging issues which needs to be addressed. This paper focuses to identify various gaps at security level of IoT layers. Considering IoT embedding smart city, it is observed that there are lots of securities threats may occur in the system at different levels which needs to be rectified. The main objective of this paper is to address those threats and area, where the improvement of the security is required along with the solutions.
