We propose an tiered incentive system called Integrity-Based Queuing (IBQ) for protection against Internet Distributed Denial-of-Service (DDoS) attacks. Our proposal can be implemented step-by-step where each integrity improvement brings a direct benefit to the autonomous system making it. IBQ proposes preferential queuing based on integrity: good, bad and middle. Since implementation can rarely be complete or network-wide we provide incremental benefit by prioritizing service for domains with better integrity. We have provided a basic analysis to relate performance to measurable integrity of the client. We have designed the architecture for authentication, queuing and defense. We have tested IBQ for applications with real-time requirements and show how performance improves with higher assurance.
