摘要: A dummy traffic strategy is described that can be implemented by mix nodes in an anonymous communication network to detect and counter active (n− 1) attacks their variants. Heartbeat messages are sent anonymously from the node back itself order establish its state of connectivity with rest network. In case under attack, flow heartbeat interrupted takes measures preserve quality anonymity it provides introducing decoy messages.
