On Verification of Restricted Extended Affine Equivalence of Vectorial Boolean Functions Özbudak, Ferruh; Yayla, Oğuz (2015-02-01) Vectorial Boolean functions are used as substitution boxes in cryptosystems. Designing inequivalent functions resistant to known attacks is one of the challenges in cryptography. In doing this, finding a fast technique for determining whether two given functions are equivalent is a significant problem. A special class of the equivalence called restricted extended affine (REA) equivalence is studied in this paper. We update the verification procedures of the REA-equivalence types given in the recent work of ...
On verification of restricted extended affine equivalence of vectorial boolean functions Sınak, Ahmet; Özbudak, Ferruh; Yayla, Oğuz; Department of Cryptography (2012) Vectorial Boolean functions are used as S-boxes in cryptosystems. To design inequivalent vectorial Boolean functions resistant to known attacks is one of the challenges in cryptography. Verifying whether two vectorial Boolean functions are equivalent or not is the final step in this challenge. Hence, finding a fast technique for determining whether two given vectorial Boolean functions are equivalent is an important problem. A special class of the equivalence called restricted extended affine (REA) equivale...
On construction of recursion operators from Lax representation Gurses, M; Karasu, Atalay; Sokolov, VV (1999-12-01) In this work we develop a general procedure for constructing the recursion operators for nonlinear integrable equations admitting Lax representation. Several new examples are given. In particular, we find the recursion operators for some KdV-type systems of integrable equations. (C) 1999 American Institute of Physics. [S0022-2488(99)03212-0].
On characterization of a Riesz homomorphism on C(X)-space AKKAR ERCAN, ZÜBEYDE MÜGE; Önal, Süleyman (Informa UK Limited, 2007-06-01) Let X be a realcompact space. We present a very simple and elementary proof of the well known fact that every Riesz homomorphism pi : C(X) -> R is point evaluated. Moreover, the proof is given in ZF.
ON THE NUMERICAL EVALUATION OF AN OSCILLATING INFINITE SERIES-III Tezer, Münevver (Informa UK Limited, 1990-01-01) An oscillating infinite series involving product of Bessel function J o(x) and an oscillating infinite series involving trigonometric function sin(x) were evaluated and computed numerically in [1] and [2] respectively. In this paper, an oscillating infinite series involving product of exponential, Bessel and trigonometric functions is evaluated. The series is transformed first into the sum of two infinite integrals by using contour integration and then the infinite integral with oscillating integrand is tra...
