Summary of Topological Study of Chaotic CBC Mode of Operation
This work provides foundational insights for cryptographers analyzing the security of symmetric-key encryption systems, but it is incremental as it summarizes previous results.
The authors tackled the problem of understanding the chaotic behavior of the Cipher Block Chaining (CBC) mode in cryptography by conducting a topological study, resulting in a proof of its chaotic nature according to Devaney's definition.
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.
