Lightweight Secure RPL: A Need in IoT

The Internet of Things (IoT) is a term which indicates the accessibility of everyday objects or things over the internet. These objects can be sensors, actuators etc. IoT supports various applications like Building & home automation, Smart cities, Smart energy, Wearables, Health care etc. but these applications are suffering from the security issues as these are accessible over the internet. In IoT, 6LowPAN is the layer which takes care of routing and uses the RPL (Routing for Low Power and Lossy Network) protocol. Current specification of RPL has many vulnerabilities which in turn causes attacks. So there is a need for improvement of this protocol. In this paper we have discussed gaps in the implementation of RPL protocol which causes security attacks and also proposed the solutions to overcome these issues.
