Among all the security issues in Voice over IP (VoIP) communications, one of the most difficult to achieve is traf- fic analysis resistance. Indeed, classical approaches pro- vide a reasonable degree of security but induce large round- trip times that are incompatible with VoIP. In this paper, we describe some of the privacy and secu- rity issues derived from traffic analysis in VoIP. We also give an overview of how to provide low-latency VoIP communi- cation with strong resistance to traffic analysis. Finally, we present a server which can provide such resistance to hun- dreds of users even if the server is compromised. Index Terms Unobservability, Anonymity, Voice over IP, Low-Latency
