Anonymous voice over IP (VoIP) communication is important for many users, in particular, journalists, human rights workers and themilitary. Recent research work has shown an increasing interest in methods of anonymous VoIP communication. This survey starts by introducing and identifying the major concepts and challenges in this field. Then we review anonymity attacks on VoIP and the existing work done to design defending strategies. We also propose a taxonomy of attacks and defenses. Finally, we discuss possible future work.
