چکیده
Bitwise-Xor of two 4-bit patterns is the 4-bit difference between them which carries useful information in Cryptography. The method to analyze cryptographic ciphering algorithms or 4-bit Substitution boxes (S-boxes) with 4-bit differences is known as Differential Cryptanalysis (DC). An analysis of DC of 4-bit bijective Crypto S-boxes based on Differential Distribution Table (DDT) is reviewed including the Strict Avalanche Criteria (SAC) of 4-bit BFs and corresponding S-Boxes categorizing SAC in two orders, namely Simple Order (SO) and Higher Order (HO). A new algorithm of adding an extension of HO-SAC is proposed and considering the comprehensive SAC, which considers SOSAC, HO-SAC and extended HO-SAC together, the properties of whole set of 65536 4-bit BFs including the comprehensive SAC are analyzed. Another new algorithm to analyze comprehensive SAC properties of 4-bit S-boxes is elaborated based on Differential Analysis Table (DAT) which turns out to be a better tool than DDT in analyzing DC of 4bit S-boxes.

متن کاملA Recursive Construction Method of S-boxes Satisfying Strict Avalanche Criterion
S(ubstitution)-boxes are quite important components of modern symmetric cryptosystems. S-boxes bring nonlinearity to cryptosystems and strengthen their cryptographic security. An S-box satisfies the strict avalanche criterion (SAC), if and only if for any single input bit of the S-box, the inversion of it changes each output bit with probability one half. We present some interesting properties ...

S-box is keystone of modern symmetric such as block and stream ciphers. It is essential component in the layout of any block system. The properties of S-boxes in Blowfish algorithm (BA) namely; Avalanche Criterion (AVAL), Strict Avalanche Criterion (SAC) and Bit Independence Criterion (BIC) are used to measure the security of the S-boxes in BA. This paper attempts to analyze these properties (A...
متن کاملApplied Endoscopic Anatomical Evaluation of the Lacrimal Sac
Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...

The aim of this study was to assess the effect of different light intensities and photoperiods on growth, survival, and the yolk sac absorb of the Persian sturgeon, Acipenser persicus, larvae. Larvae were reared from hatching to yolk sac absorb (eight days) at four light intensities (0, 50, 150 and 300 lux) and three photoperiods (00L:24D, 12L:12D and 24L:00D) which consisted of seven treatment...
