Abstract
According to one exemplary embodiment, a method for obfuscating a traffic pattern associated with a plurality of network traffic within a tunnel connection is provided. The method may include detecting the tunnel connection. The method may also include analyzing a connection environment associated with the detected tunnel connection. The method may then include determining a packet handling technique based on the analyzed connection environment, whereby the packet handling technique provides a way for creating a noise packet that will be discarded by a network stack at a target node or before the target node. The method may include determining a noise strategy based on the determined packet handling technique. The method may also include sending a plurality of noise packets into the tunnel connection based on the determined noise strategy to obfuscate the traffic pattern.
