ECRYPT's virtual labs SymLab and VAMPIRE organize DIAC -- Directions in Authenticated Ciphers.

Workshop venue:

DIAC takes place July 05-06, 2012, in the Clarion Sign Hotel Stockholm, Sweden. The hotel is within walking distance from the train station.
For accommodation see the separate site here.

DIAC will start Thursday morning. The workshop will end around 5pm on Friday. There will be a 4 invited talks along 13 contributed talks and lots of time for discussions and panels. The contributed papers were selected based on submitted papers and a refereeing process. (As for all ECRYPT conferences, there will be no formal proceedings for DIAC but a workshop record with all accepted papers.)


Users, starting with a shared secret key, need to protect messages against espionage and against forgery. Dissatisfaction with the security and performance of current approaches has led to calls for a new competition for authenticated ciphers. The purpose of this workshop is to evaluate the state of the art in authenticated encryption and gather community input regarding desired future directions.

We hope that the DIAC workshop will shape a future competition in the same way that SASC 2004 and the ECRYPT Hash Workshop 2007 shaped the ECRYPT Stream Cipher Project and the SHA-3 competition.

DIAC asks for submissions on the following topics:

Invited Speaker:

Call for papers:

There will be no formal proceedings, but a handout with abstracts will be provided to all participants. (This avoids submissions to DIAC from conflicting with submissions to forthcoming conferences with proceedings).

Call for contributions: DIAC_CFP.txt

Important dates:

May 07, 2012: submission of papers
June 04, 2012: notification of acceptance or rejection
June 18, 2012: revised version of accepted papers due
July 05-06, 2012: DIAC workshop

Each submission should start with a title, a list of the authors together with their affiliations and a short abstract describing the content of the paper. This should be followed by either a full paper or an extended abstract of at least 1 page. We also encourage submissions of panel proposals, white papers, lists of desiderata, etc. Authors of each submission must guarantee that they will present the submission at the workshop if it is accepted.

The submission server is open at

List of accepted papers for DIAC (in alphabetical order)
All accepted papers will be distributed during DIAC to the participants. Note that DIAC does not have proceedings, inclusion in the workshop records does not constitute publication.

Program Committee:


The list of topics above draws on discussions at the January 2012 Dagstuhl workshop on Symmetric Cryptography. We gratefully acknowledge suggestions from Jean-Philippe Aumasson, Eli Biham, Joan Daemen, Orr Dunkelman, Lars Knudsen, Bart Preneel, and Greg Rose.


The workshop is organized by the European Network of Excellence (ECRYPT). The workshop is an activity of ECRYPT's SymLab - Symmetric Techniques Virtual Lab and VAMPIRE - Virtual Application and Implementation Research Lab.
