Preliminary Report: On Information Hiding in Multi-Hop Radio Networks.

In this paper, we consider the problem of an adversary aiming to learn information about the network topology or the executed algorithm from some signals obtained during the algorithm's execution. The problem is defined in a very general form. However, it is mainly motivated by multi-hop ad hoc radio networks. In contrast to previous work concentrated on single-hop radio networks, this model is critically more complex due to the number of possible settings that need to be taken into account when considering different combinations of topologies and communication models. Moreover, the definition of the adversary is also ambiguous, and the adequate approach needs to depend on the adversary's aims and capabilities. This preliminary report presents a general theoretical background and some basic algorithms. We also propose some general taxonomy as a framework for future research.
