TitleAlgebraic cryptanalysis of SMS4: Gr\"obner basis attack and SAT attack compared.
Author(s) Chris Christensen, Jintai Ding, Jeremy Erickson
TypeBook, Chapter in Book, Conference Proceeding
AbstractThe SMS4 block cipher is part of the Chinese WAPI wireless standard. This paper describes the specification and offers a specification for a toy version called simplified SMS4 (S-SMS4). We explore algebraic attacks on SMS4 and S-SMS4 using Gröbner basis attacks on equation systems over GF(2) and GF(28), as well as attacks using a SAT solver derived from the GF(2) model. A comparison of SAT and Gröbner basis attacks is provided.
