This document summarizes a survey of cloud-based IP traceback frameworks. It proposes a cloud-based traceback architecture with three layers: an intra-AS layer where traceback servers in each Autonomous System (AS) collect and store traffic flow data; a traceback as a service layer where ASes expose their traceback capabilities; and an inter-AS logical links layer to facilitate efficient traceback across ASes. It then focuses on access control to prevent unauthorized users from requesting traceback information. To address this, it proposes a temporal token-based authentication framework called FACT that embeds tokens in traffic flows and delivers them to end hosts to authenticate traceback queries. The framework aims to ensure only actual recipients of packets can initiate traceback for those packets.
