On the Security of a Ticket-Based Anonymity System with Traceability Property in Wireless Mesh Networks

In 2011, Sun et al. proposed a security architecture to ensure unconditional anonymity for honest users and traceability of misbehaving users for network authorities in wireless mesh networks (WMNs). It strives to resolve the conflicts between the anonymity and traceability objectives. In this paper, we attacked Sun et al. scheme's traceability. Our analysis showed that trusted authority (TA) cannot trace the misbehavior client (CL) even if it double-time deposits the same ticket.
