Abstract
Content‐Centric Networking (CCN) is considered as a promising alternative to traditional IP‐based networking for vehicle‐to‐everything communication environments. In general, CCN packets must be fragmented and reassembled based on the Maximum Transmission Unit (MTU) size of the content delivery path. It is thus challenging to securely protect fragmented packets against attackers who intentionally inject malicious fragments to disrupt normal services on CCN‐based vehicular networks. This paper presents a new secure content fragmentation method that is resistant to Denial‐of‐Service (DoS) attacks in CCN‐based vehicular networks. Our approach guarantees the authenticity of each fragment through the immediate fragment verification at interim nodes on the routing path. Our experiment results demonstrate that the proposed approach provides much stronger security than the existing approach named FIGOA, without imposing a significant overhead in the process. The proposed method achieves a high immediate verification probability of 98.2% on average, which is 52% higher than that of FIGOA, while requiring only 14% more fragments than FIGOA.

Summary
Smart transportation based on vehicle-to-everything (V2X) communications is considered as a promising technology due to its potential to provide intelligent services for driving safety and efficiency. CCN [4] was originally proposed as a future Internet architecture that provides named data, name-based request and routing, and in-network data caching Those characteristics seem to be well suited to V2X communications that require high mobility and intermittent connectivity of vehicles. We present the design and analysis of an efficient, secure, and DoS-resilient fragment authentication technique for CCN-based vehicular networks. Our analysis results demonstrate that our approach achieves a high immediate verification probability of 98.2% on average over all the test cases, which is 52% higher than that of FIGOA, while requiring 14% more fragments than FIGOA As another layer of protection against DoS attacks, we have devised an adaptive forwarding strategy for fragments whose authenticity cannot be confirmed immediately upon receipt.
