AI_Adaptive_POW: An AI assisted Proof Of Work (POW) framework for DDoS defense

To protect the client–server architecture from a Distributed Denial of Service (DDoS) attack we present AI_Adaptive_POW. AI_Adaptive_POW protects an organization by injecting latency during communication generating client reputation adaptive puzzles, which need to be solved before server begins processing request. The framework adaptively tunes difficulty puzzle based on score calculated AI model. This slows down volume incoming adversarial traffic. Additionally, compels adversary incur cost per connection, hence making it expensive for sustain volumetric DDoS attack.
