The statistical disclosure attack (SDA) is quite an effective method for attackers
to go against an anonymity system and to reveal the information behind it. It targets
at a particular anonymity system user, tries to find its sending/receiving relationship with
others after a long term observation. In this thesis, we first make an improvement for SDA,
using weighted mean instead of the orginal arithmetic mean to calculate the cumulative
observed receiver popularity in order to get a more precise value of the attack result. Second,
we present an analysis for the effectiveness of the sender generated cover traffic, showing
that employing this kind of cover traffic helps little on protecting anonymity system users
against a sophisticated attacker. The analysis also validates an earlier empirical result of the
ineffectiveness of sender generated cover traffic. / Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science
