Cover Traffic
Classification Key
: Exterior Security, Information Disclosure
Problem
An anonymity preserving node has to receive packets from many different nodes to create the
anonymity set. If the network is experiencing slow traffic, then the packets residing in the
node has to wait for packet arrival. This delay can increase the latency of packet transfer.
How can latency be decreased while retaining data privacy?
Solution
Create dummy packets that look like real data packets inside the node. Keep a dummy traffic flow between anonymity preserving nodes to create a decoy for actual data traffic.
Known Uses
Cover traffic in an Active Bat system for location anonymity.
