Chaos-based encryption of multimedia data and design of security analysis interface as an educational tool

Data encryption has always been a topical subject. There are many encryption methods in the literature. Chaos-based encryption is considered a different area of study among the encryption practices. In this study, a novel interface was designed for chaos-based encryption to be used as an educational tool in cryptology. With this interface, the chaos-based encryption of multimedia data (picture, audio, text) can be done with one, two, or three dimensional discrete-time chaotic maps. Also, the reliability of every encryption method must be checked via certain security analyses. Thus, five different security analyses (information entropy, correlation, speed effect, differential attack, and histogram analysis), where applicable, were added into the interface to perform security analyses of chaos-based encrypted data. In this way, the chaotic encryption and security analyses, both of which need high level programming knowledge, have become available in a compact way, for those who are interested in this subject but are not knowledgeable enough about programming, hence the interface can be used as an educational tool in chaos or encryption studies.
