Efficient and secure content dissemination architecture for content centric network using ECC-based public key infrastructure

Initially, Internet was designed with the goal of sharing resources. With the recent technological advancement and huge information need, Internet has gradually shifted from resource sharing mode to information sharing mode. To meet the demands of current Internet usage pattern, content centric network (CCN) is envisaged as a clean-slate Internet architecture. This paper proposes secure content dissemination architecture for CCN using elliptic curve cryptography based public key infrastructure (ECC-PKI). The proposed scheme restores the current business model of the Internet by decoupling the encrypted content from its access control specifications while maintaining the in-network content caching mechanism of the CCN. In the proposed security architecture, content will be securely communicated between each pair of entities of CCN using ECC-based protocols. While designing proposed protocols our main aim is to minimize the computation and communication cost and to increase the performance, efficiency and security. Finally, a formal security verification using well known AVISPA simulator and BAN logic concludes that the proposed scheme is secure against the existing relevant cryptographic attacks.
