Cryptography and Communications: Discrete Structures, Boolean Functions and Sequences publishes scholarly research dedicated to improving the quality of the Discrete Structures, Boolean Functions and Sequences used in communication and cryptographic systems. This research aims to increase the speed and capacity of digital communication and strengthen security by improving the encryption necessary to combat cryptanalytic attacks. With improved encryption, communication will become more secure from the cryptanalytic attacks that threaten the confidentiality and integrity of personal data stored on and transmitted by mobile devices. Increasing the speed, reliability, and capacity of wireless communication is essential for growth, since the radio spectrum is a bounded resource.

While sometimes treated as separate entities with distinct research goals, communication and cryptography often use similar models and techniques and work in tandem in digital networks. As a result, this journal’s distinctive combination encourages researchers to strive for advancements that will improve both areas simultaneously, thus providing a publishing forum for these domains, covering all the fundamental and computational aspects of these research fields.

The journal publishes high-quality papers dealing with cryptography, error-correcting codes, communications and their interactions. Both theoretical and applied papers will be considered, with an emphasis on supporting applications. Applications include channel coding, wireless communications (e.g., mobile phones and satellite communications), security of the Internet, banking transfer security, and embedded security devices.

The scope of the journal focuses on 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. In particular, papers covering Boolean functions and sequences, without excluding any other discrete structure used in cryptography and communications, such as finite fields and other algebraic structures, are strongly encouraged. Topics include, but are not limited to:

    Boolean functions for pseudo-random generators in stream ciphers and related cryptographic criteria

    Weights and nonlinearity of Boolean functions, character sums

    Fourier and Walsh transforms and their relation to sequences and Boolean functions

    Multi-output (vectorial) Boolean functions for substitution (S-) boxes in block ciphers, differential and nonlinearity characteristics

    Designs and (single or multi-output) Boolean functions

    Diffusion in block ciphers and Boolean functions

    Cryptanalyses of stream and block ciphers and their relation to discrete structures

    Combinatorics, coding, cryptography and sequences

    Finite fields (or Galois rings), coding, cryptography, and sequences

    Connections between sequences and abstract algebra

    Permutation and multivariate polynomials over finite fields and their use in cryptography

    Linear feedback shift registers, feedback with carry shift registers, and other sequence generators

    Correlation of sequences

    Complexity measures of sequences and multisequences

    Pseudo-randomness of sequences
