The difficulties of achieving an inter-domain traceback architecture come from the issues of overcoming network operation boundaries, especially the leakage of sensitive information, the violation of the administrative permission and the cooperation among Autonomous Systems (ASes). We have proposed InterTrack in [11] as an interconnection architecture for different traceback systems and other Denial of Service (DoS) attack countermeasures. In this paper, we argue that only disclosing AS status to others can reconstruct the reverse AS path of an attack without the leakage of sensitive information or the violation of the administrative permission. Comparing our architecture with other traceback architectures, we also discuss the feasibility of our autonomous traceback architecture.
