This attack is not applicable to broadcast techniques that send messages directly to the receiver because there is no message size to trace as it is routed through the network. • Time correlation =-=[7, 9, 10, 18, 37, 38, 41]-=-. If no mixing techniques are enforced, a global eavesdropper can trace a packet from sender to receiver.
