| Abstract(in English) | In this paper we calculate the polynomial expressions of S-boxes of DES on the residue class ring of polynomials over GF(2), and extract the polynomial relations of S-boxes whose total degree is 2. By using one of the relations of S_5, we reduce the number of required known-plaintexts to 25/34 (=73.5%) of those required for the linear cryptanalyses of 14-round DES and 15-round DES by Matsui [Mat 94]. |
