Classifying 8-bit to 8-bit S-boxes based on power mappings from the point of DDT and LAT distributions
Aslan, Bora; Sakallı, Muharrem Tolga; Buluş, Ercan (Springer-Verlag Berlin, 2008)S-boxes are vital elements in the design of symmetric ciphers. To date, the techniques for the construction of S-boxes have included pseudo-random generation, finite field inversion, power mappings and heuristic techniques. ... -
On the algebraic expression of the AES S-box like S-boxes
Sakallı, Muharrem Tolga; Aslan, Bora; Buluş, Ercan; Mesut, A. Ş.; Sakallı, Fatma, Büyüksaraçoğlu; Karaahmetoğlu, O. (2010)In the literature, there are several proposed block ciphers like AES, Square, Shark and Hierocrypt which use S-boxes that are based on inversion mapping over a finite field. Because of the simple algebraic structure of ... -
On the mixcolumns linear transformation used in AES cipher
AES block cipher includes a linear transformation called MixColumns which transforms 32-bit input to 32-bit output. This transformation has the property that makes linear and differential attacks harder. In this study, we ...
