Codes of length two correcting single errors of limited size

Linear codes of length 2 over the integers modulo some integer q that can correct single errors of limited size are considered. A code can be determined by a check pair of integers. For a given range of integers, − μ ≤ e ≤ λ, such a code can only …


A lower bound on the size of the largest metrically regular subset of the Boolean cube

Let A be an arbitrary subset of the Boolean cube, and A ̂ $\widehat {A}$ be the set of all vectors of the Boolean cube, which are at the maximal possible distance from the set A. If the set of all vectors at the maximal distance from A ̂ $\widehat …


Deterministic constructions of compressed sensing matrices based on codes

Compressed sensing theory is a sampling technique which provides a fundamentally new approach to data acquisition and makes sure that a sparse signal can be reconstructed from few measurements by taking full use of sparsity. In this paper …


Binary sequences with period N and nonlinear complexity N − 2

In this paper, periodic sequences with period N and nonlinear complexity N − 2 are investigated. A necessary and sufficient condition for characterizing such sequences is established, and a recursive method is proposed to generate all possible …


Affine linear cryptanalysis

In this paper a new variant of the linear cryptanalysis method for block ciphers is proposed. It is based on the existing method of multidimensional linear cryptanalysis, but offers the option of discarding a whole half-space of linear …

Über diese Zeitschrift

Cryptography and Communications Discrete Structures, Boolean Functions and Sequences (CCDS) publishes high-quality papers discussing cryptography, error correcting codes, communications and their interactions. The journal provides a forum for the research communities of these domains, and covers all the fundamental and computational aspects of these fields.

The journal publishes both theoretical and applied papers, with an emphasis on supporting applications. Applications include channel coding; wireless communications, including mobile phones and satellite communications; security of the internet; banking transfer security; e-commerce and embedded security devices.

The central topics of the journal include discrete structures used in stream and block ciphers in symmetric cryptography; code division multiple access in communications; and random number generation for statistics, cryptography and numerical methods.
