This paper describes a new diierential-style attack, which we call the boomerang attack. This attack has several interesting applications. First, we disprove the oft-repeated claim that eliminating all high-probability diierentials for the whole cipher is suucient to guarantee security against diierential attacks. Second, we show how to break COCONUT98, a cipher designed using decorrelation tec...

In this work we present analysis for the block cipher SC2000 , which is in the Japanese CRYPTREC portfolio for standardization. In spite of its very complex and non-linear key-schedule we have found a property of the full SC2000-256 (with 256-bit keys) which allows the attacker to find many pairs of keys which generate identical sets of subkeys. Such colliding keys result in identical encryptio...

The maximum present of protein was recorded PUSA-256(24.67) at par by KGD – 1168, Pant G-186, Kw-168 having 24.32, 23.42, and 23.67 percent respectively. infected grain Callosobruchus maculatus minimum KPG-59 (21.06) PUSA 256 (25.07) percent. fresh found PUSA-256 (24.67) KPG-59(21.06).

Purpose: The newer 256-slice computed tomography coronary angiography (CTCA) has the capability of improving diagnostic performance in the detection of obstructive coronary artery disease (CAD) compared to 64-slice CTCA. The aim of this study was to compare the diagnostic performance of 64versus 256-slice CTCA in two similar populations. Methods: Our study included 120 consecutive patients who ...

Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher. First, we find a 4.5-round...
