MathCrypt 2019

(Santa Barbara, USA on Aug 18, 2019)

 Original research papers on mathematical aspects of cryptology are solicited for submission to MathCrypt 2019, the second international Workshop on Mathematical Cryptology. It will be held as an affiliated workshop of Crypto 2019 at MCC Theater. The important dates are as follows:

   + Submission: June 1st, 2019, 6:00 AM  June 5th, 23:59:00 UTC
   + Acceptance notification: July 1st, 2019
   + Final version due:  August 1st, 2019(will be published in our website)
   + Journal Version due:  September 1st, 2019(will be published in JMC)
   + Workshop presentations:  August 18th , 2019


We expect to accept submissions in twocategories: full papersand poster presentations. Full papers will be presented as talks at the workshop, while posters will be included in a poster session.  Accepted full papers will be published in the proceedings as a Special Issue of the Journal of Mathematical Cryptology.


Instructions for Authors:


For full papers, please follow the guidelines of Journal of Mathematical Cryptology: submissions must begin with an abstract of less than 150 words. The abstract must be followed by an appropriate classification according to the MSC 2010 (Mathematics Subject Classification) and a list of 3-6 keywords. The short title for the running head should contain at most 80 characters, spaces inclusive. Authors are asked to follow a few basic guidelines while formatting their paper for publication, in order for the journal to be as homogeneous in appearance as possible. Please download the LaTeX class file and the respective sample file including the instructions for formattinghere

Submissions must be submitted electronically in the PDF format, and the submission procedure and the submission link will be announced on the conference website. All submissions will be blind-refereed and submissions must be anonymous, with no author names, affiliations, or obvious references. Full papers are limited to 12 pages, excluding references and appendices if any. A poster presentation is expected to consist of 1-2 pages. (Longer papers do not mean better papers, so we recommend that authors choose the proper length for their submission depending on the topic and content.
