Abstract A novel class of covert channel, out-of-band covert channels, is presented by extending Simmons’ prisoners’ problem. This new class of covert channel is established by surveying the existing covert channel, device-pairing, and side-channel research. Terminology as well as a taxonomy for out-of-band covert channels is also given. Additionally, a more comprehensive adversarial model based on a knowledgeable passive adversary and a capable active adversary is proposed in place of the current adversarial model, which relies on an oblivious passive adversary. Last, general protection mechanisms are presented, and an argument for a general measure of “covertness” to effectively compare covert channels is given.
