This paper considers a new method for obtaining an S-box, which is one of the nonlinear
transformations used in modern block-symmetric cipher systems. This method is based on …

With the in-depth integration of traditional industries and information technology in Internet of
things, wireless sensor networks are used more frequently to transmit the data generated …

Increasing use of electronic healthcare (eHealth) services demands efficient and secure
solutions. Such solutions need to ensure the prevention of unauthorized access to the …

With the advent of the Pentium processor parallelization finally became available to Intel
based computer systems. One of the design principles of the MD4-family of hash functions …

Bent functions are those Boolean functions whose Hamming distance to the Reed–Muller
code of order 1 equal 2n-1-2n/2-1 (where the number n of variables is even). These …

In this paper we prove that in opposite to the cases of 6 and 8 variables, the Maiorana-
McFarland construction does not describe the whole class of cubic bent functions in n …

For many cryptographic primitives, eg, hashing and pseudorandom functions & generators,
doubling the output length is useful even if the doubling transformation is not reversible. For …

We use the cross-correlation function as a fundamental tool to study cryptographic
properties of Boolean functions. This provides a unified treatment of a large section of …

We introduce the notion of a weak ideal compression function, which is vulnerable to strong
forms of attack, but is otherwise random. We show that such weak ideal compression …

This paper describes a vulnerability in several implementations of the Secure Hash
Algorithm 3 (SHA-3) that have been released by its designers. The vulnerability has been …
