DESCRIPTION:Anonymous communication systems\, such as mix netw
 orks\, achieve anonymity at the expense of latency
 \, which is introduced to alter the flow of packet
 s and hinder their tracing. However\, high latency
  has a negative impact on usability. In this talk\
 , I present some recent works proposing novel late
 ncy-aware routing schemes for mixnets that reduce 
 propagation latency with a limited impact on anony
 mity. They can achieve this while also balancing t
 raffic load in the network. Additionally\, I will 
 discuss how a network can be configured to maximiz
 e anonymity while meeting an average end-to-end la
 tency constraint\, along with a security analysis 
 studying various adversarial strategies\, suggesti
 ng that these approaches will not provide a consid
 erable advantage to adversaries.
