The ability to communicate covertly through Mix-firewalls has been discussed in previous work [?]. This paper discusses the issues of implementing this theoretical construction in a prototype system. The practical issues involved in implementation are analyzed, and the actual design is given here. Suggested parameters for concatenated codes for the experimental channel are given. We compare our numerically computed information theoretic results for the data rate of covert channels through timed
