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 Shift register synthesis

It fosters the study of all aspects of cryptology -- technical as well as historical and cultural.The journal's articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering's wiretapping agency, published memoirs 8211; written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations, translated from the Arabic portions of the world's first texts on cryptanalysis and from the German a study of Nazi cryptanalysis, printed an archivally-based article on a hitherto-unknown area: German Western-Front codebreaking in World War I, reprinted Winston Churchill's 1920s pleading to be given intercepts, and many many others. The journal has published a speech by the head of the National Security Agency, the nation's codebreaking and codemaking organization that is larger than the CIA, and an analysis of the government-proposed national Data Encryption Standard. Technical articles analyzed the cryptosystems generated by cipher machines, including the famous Enigma, using algebra and have reported the solution of historical cryptograms. They have explained the linguistic basis of the Navajo language used by codetalkers in the Pacific and how digital communications can conceal illustrations or 8220;watermarks8221; that authenticate the source. One article demonstrated the inadequacy of ciphers based on music. The journal carried the obituary of the premier bibliographer of cryptology. And it reviews the many new books on the wide spectrum of ideas in cryptology and its associated fields.Publication office: Taylor & Francis, Inc., 325 Chestnut Street, Suite 800, Philadelphia, PA 19106.

Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged. 

Contributions emphasizing the fundamental concepts of crystal growth or molecular assembly and supporting further understanding of the relationship between assembly conditions and resulting properties or function of the material are highlighted. The journal does not publish routine reports of new material morphologies unless the morphology leads to significantly improved function or properties. The journal primarily covers the following:

• Crystal engineering (e.g., organic, inorganic, and hybrid solids)
• Crystal growth of inorganic, organic, and biological substances (e.g., biomineralization)
• Molecular assembly processes related to crystallization including the formation of gels, liquid crystals, colloids, and amorphous materials
• Polymorphism, polytypism
• Development of new functional nanostructured phases
• Intermolecular interactions in the solid state (e.g., hydrogen bonding, lattice energies)
• Modeling of crystal growth processes
• Prediction of crystal structure and crystal habit
• Determination and calculation of electronic distribution in the solid state
• Nucleation theory
• Molecular kinetics and transport phenomena in crystal growth
• Phase transitions
• Solvation and crystallization phenomena, modeling of crystallization processes
• Significant new ideas in industrial crystallization 

Crystal Growth & Design does not cover routine reports of crystal or molecular structures.

Crystallography Reviews publishes English language reviews of all aspects of crystallography. The main reviews are typically 20 to 80 pages long, with hundreds of references; and there are also book reviews. Topical reviews can be shorter (5000 words). The range of topics includes:- fundamentals of crystallography and applications in biology, chemistry, mathematics, physics and mineralogy as well as in industrial research; studies of the structural and symmetry aspects of solids, and includes small molecules and macromolecules as well as structural systematics and chemical design; methodological aspects include crystal growth, instrumentation and diffraction methods; and the interface of crystallography to other structure determination methods. The reviews are intended to be accessible to all scientists: not only crystallographers but also those working in related fields.Peer ReviewAll published research articles in Crystallography Reviews have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by expert reviewers.DisclaimerTaylor & Francis makes every effort to ensure the accuracy of all the information (the "Content") contained in its publications.
