Decentralized incentive-based DDoS mitigation

DDoS attacks continue to pose a major threat to the Internet’s stability. Current solutions are costly and require deployment of dedicated expansive scrubbing centers. We present DDP, an incentive based Decentralized DDoS Protection mechanism that enables operators to apply near attack-source DDoS mitigation, using network devices which are already deployed in their network. DDP is based on blockchain and smart contracts that make all accounting transparent to all participant operators, allowing them to get accurate compensation according to the effort they invest. This is a unique advantage of DDP as it enables operators to charge for protection, providing an incentive for them to participate in DDP. We provide a demo tool that enables us to measure the percentage of filtered attack traffic per the operators’ participation percentage. We show that even at participation rate of 50% we get filtration rate of 89.2% and 0% false positive.
