About: Truncated differential cryptanalysis

An Entity of Type: WikicatCryptographicAttacks, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In cryptography, truncated differential cryptanalysis is a generalization of differential cryptanalysis, an attack against block ciphers. Lars Knudsen developed the technique in 1994. Whereas ordinary differential cryptanalysis analyzes the full difference between two texts, the truncated variant considers differences that are only partially determined. That is, the attack makes predictions of only some of the bits instead of the full block. This technique has been applied to SAFER, IDEA, Skipjack, E2, Twofish, Camellia, CRYPTON, and even the stream cipher Salsa20.

  • In cryptography, truncated differential cryptanalysis is a generalization of differential cryptanalysis, an attack against block ciphers. Lars Knudsen developed the technique in 1994. Whereas ordinary differential cryptanalysis analyzes the full difference between two texts, the truncated variant considers differences that are only partially determined. That is, the attack makes predictions of only some of the bits instead of the full block.

  • 切詰差分解読法 (きりつめさぶんかいどくほう、 Truncated differential cryptanalysis)は、差分解読法を一般化したブロック暗号に対する攻撃である。 通常の差分解読法は二つの平文暗号文組の全差分を解析するが、切詰差分解読法は部分的に決定された差分のみを解析する。SAFER、IDEA、Skipjack、、Twofish、Camellia、に適用されたほか、ストリーム暗号のSalsa20にも適用された。 (ja)
