Welcome to the home page of DIAC 2015: Directions in Authenticated Ciphers. This workshop will be held on two days in downtown Singapore, between September 28 and 29, 2015. Directly following DIAC 2015 is the ASK 2015 workshop (Asian Workshop on Symmetric Key Cryptography), also held in Singapore (Nanyang Technological University). Joint participations are encouraged.

The most fundamental promise made by cryptography is that a sender and receiver, starting from nothing more than shared knowledge of a secret key, can securely exchange messages. Secret-key cryptography protects the confidentiality and integrity of the messages against any possible misbehavior by the intermediate network. Unfortunately, the trust that users place in secret-key cryptography has been repeatedly and flagrantly violated. Will the requirements of the users be better met by the next generation of authenticated ciphers?

The purpose of DIAC 2015 is to evaluate the state of the art in authenticated encryption and gather community input regarding desired future directions. DIAC 2015 emphasizes the most recent research. Comparisons of submissions to the Competition for Authenticated Encryption: Security, Applicability, and Robustness (CAESAR) are welcome. Cryptanalysis of ciphers (whether submissions or not), viewed as guidance for designers, is also welcome. Presentations of ideas for future ciphers are also welcome. Submissions of panel proposals, white papers, lists of desiderata, etc. are also welcome. See the submission page for a more comprehensive list of DIAC 2015 topics.

DIAC 2015 will take place in downtown Singapore. The formal DIAC 2015 program will begin in the morning of Monday 28 September and will end in the late afternoon of Tuesday 29 September.

DIAC 2015 is a followup to the ECRYPT DIAC workshop in Stockholm in July 2012, the DIAC 2013 workshop in Chicago in August 2013 and the DIAC 2014 workshop in Santa Barbara in August 2014.
