Исследование свойств модулярных преобразований и методов хеширования информации на их основе

Abstract

The properties of modular transformations and built on them hashing methods Keyless information (MASH-1 and MASH-2), as well as key hashing methods that are based on algorithms MASH-1 and MASH-2 by changing the initialization vector as the secret key data. Investigated various kinds of cycle functions in the scheme of iterative hash, built using modular transformations, the problem of inverting which is equivalent to solving one of the well-known complexity-theoretic problems.
