The flexible schedule of base subkeys forming into symmetric block RSB cryptoalgorithm

Analytical Modeling of Axi-Symmetric Sheet Metal Forming

The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...

the effects of integrating cooperative learning into vocabulary learning of elementary school students

the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...

All Subkeys Recovery Attack on Block Ciphers: Extending Meet-in-the-Middle Approach

We revisit meet-in-the-middle (MITM) attacks on block ciphers. Despite recent significant improvements of the MITM attack, its application is still restrictive. In other words, most of the recent MITM attacks work only on block ciphers consisting of a bit permutation based key schedule such as KTANTAN, GOST, IDEA, XTEA, LED and Piccolo. In this paper, we extend the MITM attack so that it can be...

Block Implementations of the Symmetric Qrand Jacobi

A common approach to solve problems in numerical linear algebra eeciently on modern high speed computers is to redesign the classical algorithm, which was originally developed for serial computers. In this paper, we discuss block variants of QR and Jacobi algorithms for the computation of the complete spectral decomposition of symmetric matrices. We report on numerical tests, which have been pe...
