ECC-based Efficient and Secure Access Control Scheme for Content Centric Network-A Next Generation Internet

Content centric network (CCN) is initially envisaged as a next generation Internet paradigm to cope up with the recent growing demand of content delivery. CCN reduces the network response time for content access due to its inherent content caching mechanism by intermediate CCN routers. As in CCN architecture, content is available in routers' cache, it becomes accessible to unauthorized consumers as well as vulnerable to various malicious attacks. Hence, a rigorous content access control measure should be enforced to protect the privacy and security of content in CCN, which is a promising candidate for future Internet. In this paper, we have designed a complete access control scheme for various content access requirements in CCN that includes group-based access control with dynamic group key management protocol. We have used elliptic curve cryptography (ECC), a state-of-the-art lightweight cryptosystem, to design secure access control protocols for providing high security as well as enhanced efficiency. Finally, the security analysis and performance sections confirm that our scheme is highly secured and efficient.
