It reframes the traceback problem as a polynomial reconstruction problem, and uses techniques from algebraic coding theory to provide robust methods of transmission and restriction. the scheme is a new solution to the traceback problem during a dos attack ; the honeypot for ddos, which is a tool of traceback, lures the attacker to believe that he successfully compromised a slave for his needs, convincingly simulating the architecture of a potential ddos attack ; the source - based approach to ddos defense, which is a useful adjunt to traceback systems, deploys a ddos defense system at source - end networks. attacks are detected by monitoring two - way traffic flows, and the attacks originating from source networks are stopped by rate - limiting ; the routing mechanism based on pushback treats ddos attacks as a congestion - control problem
最後，就有關ddos攻擊反向追蹤問題，從四個方面對其解決方案進行了研究：在分析比較幾種反向追蹤演算法的基礎上，著重研究了代數方法編碼反向追蹤信息的方案，該方案把追蹤重構問題當作多項式重構問題，使用代數編碼理論技術提供魯棒的傳送和重構方法，是dos攻擊過程中的反向追蹤問題的一種新的解決方法； ddos陷阱作為反向追蹤的工具，引誘攻擊者相信自己成功與所需的傀儡主機通話，令人信服地模擬出潛在ddos攻擊體系結構；基於源的ddos防禦方法作為反向追蹤有用的補充，將防禦系統部署在源網路，通過監控雙向流量檢測攻擊和限制速率終止來自源的攻擊；基於向後倒推的防禦ddos的路由機制把ddos攻擊看作擁塞控制問題，添加功能到每個路由器來檢測並優先丟棄可能屬于攻擊的包，通過向後倒推上級路由器也得到通知而把這樣的包丟棄。 -
