New research on DDoS/DRDoS attacks IP traceback based on HMAC
基于认证的反射DDoS源追踪新方案研究

Based on the Keyed-Hashing for Message Authentication(HMAC) with Key Collection Exposure,Dynamic Probabilistic Packet Marking and modern algebraic theoretics,a new Authenticated IP Traceback Scheme against DRDoS/DDoS was proposed.The results show that the scheme can achieve greater astringency and higher efficiency by adopting a new dynamic probability value sequence,and prevent the marking information from being tampered by using HMAC for authentication,thus this scheme is secure and robust.
