DDoS Mitigation: Decentralized CDN Using Private Blockchain

Abstract

Distributed Denial of Service (DDoS) attacks are intense and are targeted to major infrastructure, governments and military organizations in each country. There are a lot of mitigations about DDoS, and the concept of Content Delivery Network (CDN) has been able to avoid attacks on websites. However, since the existing CDN system is fundamentally centralized, it may be difficult to prevent DDoS. This paper describes the distributed CDN Schema using Private Blockchain which solves the problem of participation of existing transparent and unreliable nodes. This will explain DDoS mitigation that can be used by military and government agencies.
