Abstract:

A theoretical channel to communicate covertly through mix-firewalls has been discussed in previous work. This paper describes implementing this theoretical construction in an actual system. Practical issues involved in implementation are analyzed, and an actual design is given here. Suggested parameters for concatenated codes for the experimental channel are also provided, based on experimental results. We compare our numerically computed information theoretic results for the data rate of covert channels through timed mix-firewalls to the data rate obtained by our actual construction of these covert channels.
