A Lightweight and Secure IoT Communication Framework in Content-Centric Network Using Elliptic Curve Cryptography

In the recent era, content-centric network (CCN) is emerging as a future Internet paradigm to leverage scalable content distribution. Similarly, the Internet of things (IoT) is another upcoming technology which integrates as well as manages heterogeneous connected devices over the Internet. Recent literature have shown that IoT architecture can efficiently perform if it is implemented in CCN environment. In addition, considering the openness of the Internet used in IoT communication and limited capacity of IoT devices, security becomes a serious challenge which demands attention of the research community. In this paper, our main objective is to design a secure IoT communication framework that operates in CCN. A certificateless public key infrastructure is designed for our resource-constrained IoT communication framework in CCN. We have incorporated elliptic curve cryptography (ECC), a state-of-the-art lightweight cryptosystem, to ensure security of the proposed scheme. Finally, an in-depth security analysis confirms that the proposed scheme is resistant to various relevant cryptographic attacks.
