On a class of permutation trinomials in characteristic 2

Recently, Tu, Zeng, Li, and Helleseth considered trinomials of the form f ( X ) = X + a X q ( q − 1 ) + 1 + b X 2 ( q − 1 ) + 1 ∈ F q 2 [ X ] $f(X)=X+aX^{q(q-1)+ 1}+bX^{2(q-1)+ 1}\in \mathbb {F}_{q^{2}}[X]$ , where q is even and a , b ∈ F q 2 ∗ …


r-th order nonlinearity, correlation measure and least significant bit of the discrete logarithm

Each finite binary sequence (sh) is associated with a Boolean function B. The correlation measure of order k and the r-th order nonlinearity are figures of merit for the unpredictability of (sh) and B, respectively. We estimate the r-th order …

The separation of binary relative three-weight codes and its applications

The separation and its applications of binary relative three-weight codes are studied. We first present a certain formula for computing the minimum values of the cardinality of separating coordinate position (CSCP) of some codeword sets for any …


A new class of security oriented error correcting robust codes

Robust codes are codes that can detect any nonzero errore with probability 1 − Q(e) > 0. This property makes them useful in protecting hardware systems from fault injection attacks which cause an arbitrary number of bit flips. This paper presents …

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.
