Internet of Things (IoTs) is gaining increasing significance due to real-time communication and decision making capabilities of sensors integrated into everyday objects. Securing IoTs is one of the foremost concerns due to the ubiquitous nature of the sensors coupled with the increasing sensitivity of user data. Further, power-constrained nature of the IoTs emphasizes the need for lightweight security that can tailor to the stringent resource requirements of the sensors. In this work, we propose a lighweight security framework for IoTs using Identity based Cryptography. In particular, we develop a hierarchical security architecture for IoTs and further develop protocols for secure communication in IoTs using identity based cryptography. Our proposed mechanism has been evaluated using simulations conducted using Contiki and RELIC. Evaluation shows that our proposed mechanism is lightweight incurring lesser overhead and thus can be applied in IoTs.
