Batched Routing
Classification Key
: Exterior Security, Information Disclosure
Problem
A mix node has to receive packets from many different nodes to create the anonymity set. The
output from the mix network should not have any information that the user can exploit by
doing timing analysis.
How can the output of a mix node hide the timing information?
Solution
In a mix based system, collect the input data packets and when the collection reaches a threshold output all the data packets together in a batch.
Known Uses
Mix network implementing batched routing.
