MISTY1은 차등 및 선형 암호 분석에 대해 보안이 입증된 64비트 블록 암호입니다. MISTY1은 유럽 NESSIE 프로젝트에서 선정된 알고리즘 중 하나로, CRYPTREC 프로젝트에서 일본 전자정부 암호용으로 권장한 알고리즘이다. 이 논문은 이전에 알려지지 않은 4라운드 MISTY1의 고차 미분 특성을 보고합니다. FL 기능. 또한 새로 발견된 특성을 활용한 고차 차등 공격이 6라운드 MISTY1에 대해 성공했음을 보여줍니다. FL 기능. 이 공격은 데이터 복잡성이 2인 부분 하위 키를 복구할 수 있습니다.53.7 계산 복잡도는 2입니다.64.4이는 MISTY1의 이전 암호 분석보다 낫습니다.

Abstract: MISTY1 is a 64-bit block cipher that has provable security against differential and linear cryptanalysis. MISTY1 is one of the algorithms selected in the European NESSIE project, and it has been recommended for Japanese e-Government ciphers by the CRYPTREC project. This paper reports a previously unknown higher order differential characteristic of 4-round MISTY1 with the FL functions. It also shows that a higher order differential attack that utilizes this newly discovered characteristic is successful against 6-round MISTY1 with the FL functions. This attack can recover a partial subkey with a data complexity of 253.7 and a computational complexity of 264.4, which is better than any previous cryptanalysis of MISTY1.

AB - MISTY1 is a 64-bit block cipher that has provable security against differential and linear cryptanalysis. MISTY1 is one of the algorithms selected in the European NESSIE project, and it has been recommended for Japanese e-Government ciphers by the CRYPTREC project. This paper reports a previously unknown higher order differential characteristic of 4-round MISTY1 with the FL functions. It also shows that a higher order differential attack that utilizes this newly discovered characteristic is successful against 6-round MISTY1 with the FL functions. This attack can recover a partial subkey with a data complexity of 253.7 and a computational complexity of 264.4, which is better than any previous cryptanalysis of MISTY1.
