Abstract: Internet of things involves network of Nodes (sensors, Actuators, fog, cloud etc). Sensor node is a small in size, computing power and storage capacity is less. Due to this nature of Sensor the security module is not incorporated in it. So IoT Nodes has more scope for the Intruders, to attack the systems by using this weak connection of Nodes. Lot of research work has to do in this area, to establish a secure connectivity among various IoT nodes. While accomplishing the secure connectivity of things in IoT, need to consider all the security parameters like (confidentiality, authentication, integrity, etc.). The existing techniques/ Algorithms for secure connectivity of devices are not developed for nodes that which used in an IoT technology and not deal with all security parameters. This paper addressed the various existing secure connectivity techniques with advantages and disadvantages, that which is used to direct Research towards development of secure connectivity Techniques for IoT nodes.
