An Autonomous System Based Security Mechanism for Network Coding Applications in Content-Centric Networking

Content-Centric Networking (CCN), is built on the notion of content-based security. With the integration of Network Coding (NC) into CCN to contribute to the best performance, security, one of the key features of CCN has been left behind. Though the permission for encoding/recoding content packets at producers and intermediate routers provides performance benefits, it also introduces additional security issues and disables existing security practices. In this paper, we fill the gap by analyzing new security challenges brought accordingly and proposing an Autonomous Systems (AS-s) based security mechanism for NC applications in CCN. It can not only guarantee the optimal performance of NC, but also offer the assurance for Integrity, Origin Authentication and Correctness of content packets, together with proving trustworthiness among border routers. More importantly, we also shed light on the performance issues and implementation problems of the mechanism.
