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 Construction of 20 x 20 and 24 x 24 Binary Matrices with Good Implementation Properties for Lightweight Block Ciphers and Hash Functions
Sakallı, Muharrem Tolga; Akleylek, Sedat; Aslan, Bora; Buluş, Ercan; Sakallı, Fatma Büyüksaraçoğlu (Hindawi Ltd, 2014)We present an algebraic construction based on state transform matrix (companion matrix) for n x n (where n + 2(k), k being a positive integer) binary matrices with high branch number and low number of fixed points. We also ...
