Accession number: 05068829804 Title: New system of multivariate quadratic equations for Rijndael Authors: Li, Na; Chen, Wei-Hong Author affiliation: Dept. of Appl. Math., Info. Eng. Inst., Info. Eng. Univ., Zhengzhou 450002, China Serial title: Dianzi Yu Xinxi Xuebao/Journal of Electronics and Information Technology Abbreviated serial title: Dianzi Yu Xinxi Xuebao Volume: v 26 Issue: n 12 Issue date: December 2004 Publication year: 2004 Pages: p 1990-1995 Language: Chinese ISSN: 1009-5896 CODEN: DKXUEC Document type: Journal article (JA) Publisher: Science Press, Beijing, China Abstract: Because the algebraic expression of Rijndael S box is a composition of the converse function with a q-polynomial over GF(28), in this paper the variables of S box are supposed rationally and the relations between these variables are analyzed, then a new system of multivariate quadratic equations over GF(28) are used to describe completely Rijndael, the cryptanalysis of Rijndael can be written as a problem of solving the system of multivariate quadratic equations. This system is simpler than Murphy and Robshaw's, and has a lower complexity while applying XSL technique.
