© Nicolas Brodu. 2003 The astrolabe is an ancient astronomical computer for solving problemsrelating to time and the position of the sun and stars in the sky.Historians credit the invention of the astrolabe to classical Greece.Brass astrolabes were highly developed in the Islamic world of the 8thcentury and later. chiefly as an aid to navigation and as a way offinding the direction of Mecca. In the Middle Ages it found its wayback to Europe and became the chief navigational instrument until theinvention of the sextant in the 18th century.

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.

CrystEngComm is the forum for the design and understanding of crystalline materials. It publishes studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. All papers should involve the use or development of a design or optimisation strategy.
