Designs, Codes and Cryptography An International Journal Editors-in-Chief (+deputy) Dieter Jungnickel Mathematics Institute, Justus-Liebig-University, Giessen, Germany Ronald C. Mullin Dept. of Combinatorics and Optimization, University of Waterloo, Ontario, Canada Scott A. Vanstone Dept. of Combinatorics and Optimization, University of Waterloo, Ontario, Canada AIMS AND SCOPE Designs, Codes and Cryptography is a technical journal publishing survey and original papers in the designated areas. There is a great deal of activity in design theory, coding theory and cryptography and recently there has been considerable research done which brings together more than one of the subjects. Journals currently exist for each of the individual areas but none encourage the interaction of the disciplines. The aim of this journal is to provide a forum for high quality papers of both a theoretical and a practical nature which bridge more than one of these areas. The scope of the new journal is wide. Papers emphasizing the algebraic and geometric aspects of any of the areas considered, with papers touching more than one of the areas being especially welcome. The journal is published four times per year with distribution to engineers, mathematicians, computer scientists and other in education, industry and government. INSTRUCTIONS FOR AUTHORS Authors are encouraged to submit high quality, original works which has neither appeared, nor is under consideration by, other journals. PROCESS FOR SUBMISSION 1. Authors should submit five hard copies of their final manuscript to: Mrs. Karen S. Cullen DESIGNS, CODES AND CRYPTOGRAPHY - Editorial Office Kluwer Academic Publishers Tel.: 617-871-6300 101 Philip Drive FAX: 617-871-6528 Norwell, MA 02061 For prompt attention, all correspondence can be directed to this address. 2. Enclose with each manuscript, on a separate page, from three to five key words. 3. Enclose originals for the illustrations, in the style described below, for one copy of the manuscript. Photocopies of the figures may accompany the remaining copies of the manuscript. Alternatively, original illustrations may be submitted after the paper has been accepted. 4. Enclose a separate page giving the preferred mailing address (including street and bldg. nos) of the contact author for correspondence and return of proofs. Please be sure to include a telephone number, fax number and e-mail address. 5. The refereeing is done by anonymous reviewers. 6. All papers should be written in English. STYLE FOR MANUSCRIPT 1. Typeset, double or 1 1/2 space; use one side of sheet only (laser printed, typewritten and good quality duplication acceptable). 2. Use an informative title for the paper and include an abstract of 100 to 250 words at the head of the manuscript. The abstract should be a carefully worded description of the problem addressed, the key ideas introduced, and the results. Abstracts will be printed with the article. 3. Provide a separate double-spaced sheet listing all footnotes, beginning with "Affiliation of author" and continuing with numbered footnotes. Acknowledgement of financial support may be given if appropriate. 4. References should appear in a separate bibliography at the end of the paper in alphabetical order and numbered consecutively with items referred to in the text by arabic numerals in brackets (e.g., [1]). References should be complete, in the following style: Style for papers: Author(s), title, volume, year of publication and inclusive page numbers. Style for books: Author(s), title, publisher and location, volume, year of publication, chapter or page numbers (if desired). Examples as follows: [1] K.T. Arasu and Alexander Pott, On quasiregular collineation groups of projective planes, Designs, Codes and Cryptography, Vol. 1, No. 1 (1991) pp. 83-92. [2] P. Dembowski, Finite Geometries, Springer-Verlag, Berlin- Heidelberg, New York (1968). [3] K. Koyama and K. Ohta, Identity-based conference key distribution systems, Advances in Cryptology: Proceedings of Crypto 87 (C. Pomerence, ed.) Lecture Notes in Computer Science, Springer-Verlag, New York, 293 (1988) pp. 175-194. 5. Type or mark mathematical copy exactly as they should appear in print. Journal style for letter symbols is as follows: variables, italic type (indicated by underline); constants, roman text type; matrices and vectors, boldface type (indicated by wavy underline). In word-processor manuscripts, use appropriate typeface. It will be assumed that letters in displayed equations are to be set in italic type unless you mark them otherwise. All letter symbols in text discussion must be marked if they should be italic or boldface. Indicate best breaks for equations in case they will not fit on one line. 6. Provide a separate sheet listing all figure captions, in proper style for the typesetter, e.g., "Fig. 3. Examples of the zero crossing of the second derivative of the (a) Gaussian and (b) sine filter for the same input function." STYLE FOR ILLUSTRATIONS 1. Original for illustrations should be sharp, noise-free, and of good contrast. We regret that we cannot provide drafting or art service. 2. Line drawings should be in laser printer output or in India ink on paper, or board. Use 8 1/2 by 11-inch size sheets if possible, to simplify handling of the manuscript. 3. Each figure should be mentioned in the text and numbered consecutively using Arabic numerals. Specify the desired location of each figure in the text, but place the figure itself of a separate page following the text. 4. Number each table consecutively using Arabic numerals. Please label any material that can be typeset as a table, reserving the term "figure" for material that has been drawn. Specify the desired location of each table in the text, but place the table itself on a separate page following the text. Type a brief title above each table. 5. All lettering should be large enough to permit legible reduction. 6. Photographs should be glossy prints, of good contrast and gradation, and any reasonable size. 7. Number each original on the back. 8. Include a separate sheet listing the captions for all figures. PROOFING Page proofs for articles to be included in a journal issue will be sent to the contact author for proofing. The proofread copy should be received back by the Publisher within 72 hours.
