<br>
This workshop is a forum of mathematicians, computer scientists,
engineers and physicists performing research on finite field
arithmetic, interested in communicating the advances in the theory,
applications, and implementations of finite fields. The workshop
will help to bridge the gap between the mathematical theory of
finite fields and their hardware/software implementations and
technical applications.<br>
<br>
Please feel free to forward this information to any college who
might be interested.<br>

New announcement: Abstracts and Presentations (ASP) Session<br>
Due to numerous requests, the Steering Committee of WAIFI is also
announcing an additional session, which we call the Abstracts and
Presentations (ASP) Session. In the spirit of Crypto Rump Session,
the ASP Session allows the participants to submit abstracts which
will be reviewed by a committee. The authors will then be invited to
present their papers while their abstracts will appear in a separate
booklet as "the ASP Session Abstracts", to be distributed during the
workshop.<br>
Everyone is invited to submit an abstract for the ASP Session of
WAIFI 2012. The submission should begin with the title, the list of
authors, the list of keywords followed by the 1/2-page abstract. The
same author or the same group of authors may submit only one
abstract. Also the submission should not exceed a single Letter/A4
page. Please submit a TEXT or PDF file.<br>
The ASP Session Review Committee will quickly review your submission
and respond to you in a timely manner.<br>
<br>
Please send your submission to:<br>
* Francisco Rodríguez-Henríquez (francisco/at/cs.cinvestav.mx)<br>
* Ferruh Ozbudak (ozbudak/at/metu.edu.tr)<br>
<br>
Important dates:<br>
* Submission deadline: June 15th, 2012<br>
* Acceptance notification: June 26th, 2012<br>
