Abstract

Sometimes the analysis of covert channel is weakly dependent on the correctness of probabilistic models, but more often the result of such analysis is seriously dependent on the choice of aprobabilistic model. We show how the problem of detection of covert communications depends on the correctness of the choice of probabilistic model. We found the dependence of judgments about invisibility of covert communication from the bans in a probabilistic model of the legal communication.
