International Association for Cryptologic Research

The International Association for Cryptologic Research (IACR) is a non-profit scientific organization that furthers research in cryptology and related fields. The IACR was organized at the initiative of David Chaum at the CRYPTO '82 conference.

The IACR organizes and sponsors three annual flagship conferences, four area conferences in specific sub-areas of cryptography, and one symposium:

Several other conferences and workshops are held in cooperation with the IACR. Starting in 2015, selected summer schools will be officially sponsored by the IACR. CRYPTO '83 was the first conference officially sponsored by the IACR.

The IACR publishes the Journal of Cryptology, in addition to the proceedings of its conference and workshops. The IACR also maintains the Cryptology ePrint Archive, an online repository of cryptologic research papers aimed at providing rapid dissemination of results.

Asiacrypt (also ASIACRYPT) is an international conference for cryptography research. The full name of the conference is currently International Conference on the Theory and Application of Cryptology and Information Security, though this has varied over time. Asiacrypt is a conference sponsored by the IACR since 2000, and is one of its three flagship conferences. Asiacrypt is now held annually in November or December at various locations throughout Asia and Australia.

Initially, the Asiacrypt conferences were called AUSCRYPT, as the first one was held in Sydney, Australia in 1990, and only later did the community decide that the conference should be held in locations throughout Asia. The first conference to be called "Asiacrypt" was held in 1991 in Fujiyoshida, Japan.

Cryptographic Hardware and Embedded Systems (CHES) is a conference for cryptography research, focusing on the implementation of cryptographic algorithms. The two general areas treated are the efficient and the secure implementation of algorithms. Related topics such as random number generators, physical unclonable function or special-purpose cryptanalytical machines are also commonly covered at the workshop. It was first held in Worcester, Massachusetts in 1999 at Worcester Polytechnic Institute (WPI). It was founded by Çetin Kaya Koç and Christof Paar. CHES 2000 was also held at WPI; after that, the conference has been held at various locations worldwide. After the two CHES' at WPI, the locations in the first ten years were, in chronological order, Paris, San Francisco, Cologne, Boston, Edinburgh, Yokohama, Vienna, Washington, D.C., and Lausanne. Since 2009, CHES rotates between the three continents Europe, North America and Asia. The attendance record was set by CHES 2018 in Amsterdam with about 600 participants.

Eurocrypt (or EUROCRYPT) is a conference for cryptography research. The full name of the conference is now the Annual International Conference on the Theory and Applications of Cryptographic Techniques. Eurocrypt is one of the IACR flagship conferences, along with CRYPTO and ASIACRYPT.
