On the Security of a Ticket-Based Anonymity System with Traceability Property in Wireless Mesh Networks
ABSTRACT
In 2011, Sun et al. [CHECK END OF SENTENCE]
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.
