Abstract

We will discuss the threat of covert timing channels. A Shannon type analysis will be done of the problem. We will show how the NRL Pump can be used to lessen the threat of covert timing channels. We will also show how covert timing channels arise in anonymity networks, even though Mix-firewalls are in use. Finally, we will go off topic and discuss the movement of action potentials through neurons and how they relate to covert timing channels.

Bio

Ira Moskowitz received his BS (1978) and PhD (differential topology, 1983) degrees in mathematics from SUNY Stony Brook. He has been a math professor at Texas A&M University and Elmhurst College. He also worked as a mathematician at the Center for Naval Analyses. Since 1989 he has been at the US Naval Research Laboratory in Washington, DC. He is the lead scientist on the Concealed Knowledge project. His major interests are the mathematical foundations of covert channels and he is the co-inventor of the NRL Pump.
