Mitigating Content Poisoning in Content Centric Network: A Lightweight Approach

The internet paradigm was designed to forward packets from host-to-host. But nowadays the focal point has moved to data. The Internet Centric Network (ICN) provides architectures to meet this requirement. The Content Centric Network (CCN) is the most widely used ICN architecture. Information Centric Network's ability to perform in-network caching lead to faster retrieval of data on subsequent request. Although latency is solved, caching in a router makes it vulnerable to attacks that focus on the cache. One such attack is content poisoning, that will fill the router with poisoned content making the end user difficult to retrieve original valid data. In this paper, we propose a solution to mitigate content poisoning attack that will consume minimum time and require minimal storage overhead during the verification process.
