Mobile devices such as smartphones are
prime candidates for the application of mixing techniques to provide anonymity
for small groups of individuals numbering 30 to 40 members. In this work, a
Chaum mix inspired, smartphone based network that uses the Short Message
Service (SMS) is proposed. This system leverages both techniques used by
current anonymity networks as well as knowledge gained from current and past
research to make messages private and untraceable. Previously published attacks
to anonymous systems are addressed as well as mitigation techniques.
