  In cryptography, block ciphers are the most fundamental elements in many
symmetric-key encryption systems. The Cipher Block Chaining, denoted CBC,
presents one of the most famous mode of operation that uses a block cipher to
provide confidentiality or authenticity. In this research work, we intend to
summarize our results that have been detailed in our previous series of
articles. The goal of this series has been to obtain a complete topological
study of the CBC block cipher mode of operation after proving his chaotic
behavior according to the reputed definition of Devaney.
