Lightweight Source Authentication And Path Validation
COMM(2014)
摘要
In-network source authentication and path validation are fundamental primitives to construct higher-level security mechanisms such as DDoS mitigation, path compliance, packet attribution, or protection against flow redirection. Unfortunately, currently proposed solutions either fall short of addressing important security concerns or require a substantial amount of router overhead. In this paper, we propose lightweight, scalable, and secure protocols for shared key setup, source authentication, and path validation. Our prototype implementation demonstrates the efficiency and scalability of the protocols, especially for software-based implementations.
