State-of-the-art in Chaotic Iterations based pseudorandom numbers generators Application in Information Hiding

International audienceThe confidentiality of information transmitted through the Internet requires an intensive use of pseudorandom number generators having strong security properties. For instance, these generators are used to produce encryption keys, to encrypt data with a one-time pad process, or to dissimulate information into cover media. In the previous International Conference on Evolving Internet (Internet 09, 10, and 11), we have proposed the use of discrete chaotic iterations to build pseudorandom number generators that receive two inputted possibly deficient generators, and mix them to produce pseudorandom numbers with high statistical qualities. In this article, we summarize these contributions and we propose simple applications of these generators for encryption and information hiding. For each application, firsts experimental evaluations are given, showing that an attacker using these statistics as detection tools cannot infer the presence of an hidden message into given cover documents
