摘要
Information-Centric Networking(ICN)is considered a viable strategy for regulating Internet consumption using the Internet’s underlying architecture.Although Named Data Networking(NDN)and its reference-based implementa-tion,the NDN Forwarding Daemon(NFD),are the most established ICN solu-tions,their vulnerability to the Content Poisoning Attack(CPA)is regarded as a severe threat that might dramatically impact this architecture.Content Poisoning can significantly minimize the impact of NDN’s universal data caching.Using verification signatures to protect against content poisoning attacks may be imprac-tical due to the associated costs and the volume of messages sent across the net-work,resulting in high computational costs.Therefore,in this research,we designed a method in NDN called Bird Swarm Optimization Algorithm-Based Content Poisoning Mitigation(BSO-Content Poisoning Mitigation Scheme).By aggregating the security information of entire routers along the full path,this sys-tem introduces the BSO to explore the secure transmission path and alter the con-tent retrieval procedure.Meanwhile,based on the determined trustworthy value of each node,the BSO-Content Poisoning Mitigation Scheme can bypass malicious routers,preventing them from disseminating illicit content in the future.Addition-ally,the suggested technique can minimize content poisoning utilizing removing erroneous Data packets from the cache-store during the pathfinding process.The proposed method has been subjected to extensive analysis compared with the ROM scheme and improved performance justified in several metrics.BSO-Con-tent Poisoning Mitigation Scheme is more efficient and faster than the ROM tech-nique in obtaining valid Data packets and resulting in a higher good cache hit ratio in a comparatively less amount of time.
