AFRICACRYPT 2010, May 03-06, 2010, Stellenbosch, South Africa

After two successful Africacrypts (Africacrypt 2009 in Gammarth, Tunisia and Africacrypt 2008 in Casablanca, Morocco), Africacrypt 2010 will take place in Stellenbosch, South Africa. For more information, such as program, registration, practical matters see:

http://2010.africacrypt.com

Call for papers:

The conference seeks original contributions in cryptology: We welcome submissions about new cryptographic primitive proposals, cryptanalysis, security models, hardware and software implementation aspects, cryptographic protocols and applications. We also consider submissions about cryptographic aspects of network security, complexity theory, information theory, coding theory, number theory, and quantum computing.
The proceedings of Africacrypt 2010 will be published by Springer Verlag as Volume 6055 in the Lecture Notes in Computer Science (LNCS) series. The proceedings will be available during the conference.

Important deadlines and dates (revised):

January 05, 2010:	registration of paper (title, abstract)
January 10, 2010:	submission deadline
February 19, 2010:	notification of acceptance or rejection
February 28, 2010:	revised version of accepted papers due
May 03-06, 2010:	Africacrypt 2010

No new submissions will be accepted after the submission of abstracts deadline (Jan 05); it is still possible to modify the submissions until Jan 10.

Instructions for Authors of Papers

Submissions must not substantially duplicate work that any of the authors has published elsewhere or has submitted in parallel to any other conference or workshop with formally published proceedings. Information about submissions may be shared with program chairs of other conferences for the purpose of detecting duplication. Accepted submissions may not appear in any other conference or workshop with proceedings.
Submissions must be anonymous, with no author names, affiliations, acknowledgments, or obvious references. Each submission should begin with a title, a short abstract, and a list of keywords, and an introduction that summarizes the contributions of the paper at a level appropriate for a non-specialist reader. Submissions not meeting these guidelines risk rejection without consideration of their merits.
The page limit for submissions is 18 pages in LNCS format (see http://www.springeronline.com/lncs) including references and appendices. Up to 12 pages of additional supporting information may be provided, but committee members will read this information at their discretion, so the paper should be intelligible and self-contained within the 18 page LNCS limit. The final versions of accepted papers will be limited to 18 pages including references and appendices.
Papers must be submitted electronically. A detailed description of the electronic submission procedure is available at
https://www.hyperelliptic.org/conferences/iChair/ Submissions must conform to this procedure. Late submissions and non-electronic submissions will not be considered. No new submissions will be accepted after the submission of abstracts deadline (Jan 05); it is still possible to modify the submissions until Jan 10. Authors of accepted papers must guarantee that their paper will be presented at the conference.
Accepted papers will be published in Springer-Verlag's Lecture Notes in Computer Science and will be available at the conference. Instructions about the preparation of a final proceedings version will be sent to the authors of accepted papers.
