| Résumé | In cryptography, Cipher Block Chaining (CBC) mode of operation presents a very popular way of encryption that is used in numerous applications. In our previous research work, we have been proven that, under some conditions, this mode of operation can exhibit a chaotic behavior according to the reputed definition of Devaney. The quantitative study of this chaotic CBC has been deepened later by evaluating both its level of sensibility and of expansivity. In this paper, our objective is now to further develop the evaluation of the CBC dynamics, by obtaining a complete topological study of this mode of operation. Such an evaluation encompasses both the qualitative property of topological mixing and its level of topological entropy, which is indeed a quantitative measure of disorder. |
