초록
Block Cipher SEED which was developed by KISA are not only Korea national standard algorithm of TTA but also one of standard 128-bit block ciphers of ISO/IEC. Since SEED had been developed, many analyses were tried but there was no distinguishing cryptanalysis except the 7-round differential attack in 2002. The attack used the 6-round differential characteristic with probability and analyzed the 7-round SEED with chosen plaintexts. In this paper, we propose a new 6-round differential characteristic with probability and analyze the 7-round SEED with chosen plaintexts.
Abstract
Block Cipher SEED which was developed by KISA are not only Korea national standard algorithm of TTA but also one of standard 128-bit block ciphers of ISO/IEC.

The attack used the 6-round differential characteristic with probability and analyzed the 7-round SEED with chosen plaintexts. In this paper, we propose a new 6-round differential characteristic with probability and analyze the 7-round SEED with chosen plaintexts.
