BlockJack: Blocking IP Prefix Hijacker in Inter-Domain Routing

We propose "BlockJack", a system based on a distributed and tamper-proof consortium blockchain that aims at blocking BGP prefix hijacking attacks. We implement BlockJack using Hyperledger Fabric Blockchain and Quagga software package and we perform initial sets of experiments to evaluate its efficacy. The Evaluation results show that BlockJack is able to handle multiple attacks caused by AS paths changes during a BGP prefix hijacking. In experiment settings with ten routers, BlockJack takes on average 0.086 (with standard deviation of 0.013 seconds) to block BGP prefix hijacking attacks.
