Network approaches for anonymous communication have been extant for some time. Unfortunately, there are limitations with these approaches. In this paper, we first expose the limitations of existing anonymous communication networks. We then present an anonymous Internet communication technique based on IPSec. Our technique provides bi-directional, real-time anonymous Internet communication that is resistant traffic analysis for any TCP/IP applications. We describe the signaling protocols and the implementation of our architecture. Our technique is easily implemented in security gateways or IP router that supports IPSec.
