Abstract:
This paper describes the architecture of BlankNet, a secure Virtual Private Network, which is capable of protecting its users against most kinds of attacks to traffic secrecy, including traffic analysis attacks. A key aspect of the BlankNet architecture is the definition of the allowed packet communication patterns: we call this pattern a virtual topology. Among the various possible solutions, the binary cube topology is found to have favorable delay characteristics in light and moderate network traffic scenarios, while under heavy loading a completely connected topology turns out to be the most convenient one.
