A Note on the Problem of Semantic
Interpretation Agreement in Steganographic Communications School of Computing, University of Portsmouth, Portsmouth, United
Kingdom
Abstract This paper describes a solution to one of the fundamental problems in stegnagoraphy, namely that two participants can agree on a common interpretation of the communicated hidden message. Thus far, most literature in the field of steganography has focused on two problems: first, the embedding (and extraction) of hidden content and second, the analysis of suspicious messages by an external attacker. We argue here that there is a third fundamental dimension that characterises steganography, namely the ability of the three parties to interpret hidden content. We offer here one solution based on the Diffie-Hellman key-agreement calculation that leads to interpretation agreement.
