A highly nonlinear S-box based on a fractional linear transformation
We study the structure of an S-box based on a fractional linear transformation applied on the Galois field [Formula: see text]. The algorithm followed is very simple and yields an S-box with a very high ability to create confusion in the data. The cryptographic strength of the new S-box is critically analyzed by studying the properties of S-box such as nonlinearity, strict avalanche, bit indepe...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

15 صفحه اولMatrix Power S-Box Construction
The new symmetric cipher S-box construction based on matrix power function is presented. The matrix consisting of plain data bit strings is combined with three round key matrices using arithmetical addition and exponent operations. The matrix power means the matrix powered by other matrix. The left and right side matrix powers are introduced. This operation is linked with two sound one-way func...
متن کاملThe Matrix Power Function and Its Application to Block Cipher S-box Construction
In this paper, we are continuing the security investigation of the new S-box function based on so-called matrix power function proposed earlier by the same authors. Security is considered against algebraic cryptanalysis. We claim that constructed S-box function is a candidate to be a one-way function since we showed that its inversion is related with one known NP-complete problem, namely with a...
