Essay

The dissertation is dedicated to solving of an actual scientific task of stream ciphers' security evaluation against designed statistical attacks that summarize and unify already known attacks. Theoretical basis of the research is Probability theory and Boolean functions' theory. The proposed methods allow to prove modern stream ciphers' security against most powerful choosen-IV statistical attacks. The proposed methods can be expedienlty used for expert research of stream ciphers, intended for protection of Ukrainian national informational resources.
