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

Workshop venue:

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.)

Topic:

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:

• Components and combinations
• block ciphers
• dedicated stream ciphers
• stream ciphers based on block ciphers
• dedicated hash functions, sponges, etc.
• hash functions based on block ciphers
• dedicated MACs
• MACs based on hash functions
• MACs based on block ciphers
• authenticated encryption based on any of the above
• dedicated ciphers with built-in authentication
• Attacks
• cryptanalysis of symmetric systems
• side-channel attacks on symmetric systems
• real-world costs of attacks
• Implementations
• APIs
• software
• FPGAs
• ASICs
• comparisons
• Requirements
• quantitative security: e.g., is 80 bits enough?
• qualitative security: e.g., MAC vs. PRF, INT-PTXT vs. INT-CTXT
• robustness: e.g., security under nonce reuse, security against idiots
• side-channel resistance
• handling of limited randomness
• safety of using a key for many messages: 2^32? 2^64?
• key agility
• throughput in software, FPGA, ASIC
• parallelizability, incrementality, etc.
• ASIC area budgets, FPGA slice budgets, etc.
• power limits, energy limits, etc.
• bandwidth: short plaintexts, ciphertexts, authenticators
• flexibility: e.g., variable authenticator lengths
• convenience: e.g., one-pass, intermediate tags
• use cases

Invited Speaker:

• Joan Daemen (STMicroelectronics, Belgium)
• David McGrew (Cisco Systems, USA)
• Phillip Rogaway (University of California, Davis, USA)
• Palash Sarkar (Indian Statistical Institute, Kolkata, India)

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:

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 http://hyperelliptic.org/conferences/diac/iChair/submit.php.

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.
