A Review on Security and Privacy Protocols in IoT

Internet of things (IoT) is a trending concept in the field of computer networks in which various heterogeneous devices are connected to each other to collect the data from various sensor nodes. It is a system in which everyday things with embedded hardware/devices are connected to a network or it can be said that they are simply online. Sensor collects the information from their surroundings, process it and forward the information to the distant location for further processing. In today¿s scenario IoT finds its application everywhere like in classrooms, shopping malls, offices, agriculture, retails, multimedia, weather prediction, traffic monitoring, healthcare, pollution control, vehicles and homes. This diversified range of IoT application indicate that it has become an integral part of our lives. Security and privacy always remain the major concerns in the field of IoT network as most of the devices in the IoT environment are transmitting unencrypted information in an open and hostile environment. This work is mainly focused on the various issues on security and privacy for the IoT network.
