Comparative Analysis of Security Techniques in Internet of Things

Internet of Things (IoT) comprises of sensor devices that are connected through with each other and communicate with the help of internet gateway. In today’s environment as demand of data increase day by day and transfer data in secure manner from one device to another is a critical risk in the breakage of security of data in IoT. There are number of vulnerability activities are performed by attackers during data transmission such as breakage of connection, forgery of information, packet drop, and incorrect information sends to receiver node etc. In this paper an attempt has been made to present systematic review and comparative analysis on various security aspects and existing techniques to handle security in IoT. After that we provide various security protocols and their comparison in perspective of security aspects. Furthermore, we provide various cryptography techniques and their comparison with different parameters.
