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.[1]

Key Information

Activities

[edit]

The IACR organizes and sponsors three annual flagship conferences, four area conferences in specific sub-areas of cryptography, and one symposium:[2]

  • Crypto (flagship)
  • Eurocrypt (flagship)
  • Asiacrypt (flagship)
  • Fast Software Encryption (FSE)
  • Public Key Cryptography (PKC)
  • Cryptographic Hardware and Embedded Systems (CHES)
  • Theory of Cryptography (TCC)
  • Real World Crypto Symposium (RWC)

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.[3]

Asiacrypt

[edit]

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

[edit]

Cryptographic Hardware and Embedded Systems (CHES) is a conference for cryptography research,[4] 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.[5] The attendance record was set by CHES 2018 in Amsterdam with about 600 participants.

Eurocrypt

[edit]

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.

Eurocrypt is held annually in the spring in various locations throughout Europe. The first workshop in the series of conferences that became known as Eurocrypt was held in 1982. In 1984, the name "Eurocrypt" was first used. Generally, there have been published proceedings including all papers at the conference every year, with two exceptions; in 1983, no proceedings was produced, and in 1986, the proceedings contained only abstracts. Springer has published all the official proceedings, first as part of Advances in Cryptology in the Lecture Notes in Computer Science series.

Fast Software Encryption

[edit]

Fast Software Encryption, often abbreviated FSE, is a workshop for cryptography research, focused on symmetric-key cryptography with an emphasis on fast, practical techniques, as opposed to theory. Though "encryption" is part of the conference title, it is not limited to encryption research; research on other symmetric techniques such as message authentication codes and hash functions is often presented there. FSE has been an IACR workshop since 2002, though the first FSE workshop was held in 1993. FSE is held annually in various locations worldwide, mostly in Europe. The dates of the workshop have varied over the years, but recently, it has been held in February.

Public Key Cryptography

[edit]

PKC or Public-Key Cryptography is the short name of the International Workshop on Theory and Practice in Public Key Cryptography (modified as International Conference on Theory and Practice in Public Key Cryptography since 2006).

Theory of Cryptography

[edit]

The Theory of Cryptography Conference, often abbreviated TCC, is an annual conference for theoretical cryptography research.[6] It was first held in 2004 at MIT, and was also held at MIT in 2005, both times in February. TCC became an IACR-sponsored workshop in 2006. The founding steering committee consists of Mihir Bellare, Ivan Damgard, Oded Goldreich, Shafi Goldwasser, Johan Hastad, Russell Impagliazzo, Ueli Maurer, Silvio Micali, Moni Naor, and Tatsuaki Okamoto.

The importance of the theoretical study of Cryptography is widely recognized by now. This area has contributed much to the practice of cryptography and secure systems as well as to the theory of computation at large.

The needs of the theoretical cryptography (TC) community are best understood in relation to the two communities between which it resides: the Theory of Computation (TOC) community and the Cryptography/Security community. All three communities have grown in volume in recent years. This increase in volume makes the hosting of TC by the existing TOC and Crypto conferences quite problematic. Furthermore, the perspectives of TOC and Crypto on TC do not necessarily fit the internal perspective of TC and the interests of TC. All these indicate a value in the establishment of an independent specialized conference. A dedicated conference not only provides opportunities for research dissemination and interaction, but helps shape the field, give it a recognizable identity, and communicate its message.

Real World Crypto Symposium

[edit]

The Real World Crypto Symposium is a conference for applied cryptography research, which was started in 2012 by Kenny Paterson and Nigel Smart. The winner of the Levchin Prize is announced at RWC.[7] [8] Announcements made at the symposium include the first known chosen prefix attack on SHA-1[9][10] and the inclusion of end-to-end encryption in Facebook Messenger.[11] Also, the introduction of the E4 chip took place at RWC.[12] Flaws in messaging apps such as WhatsApp were also presented there.[13]

International Cryptology Conference

[edit]

CRYPTO, the International Cryptology Conference, is an academic conference on all aspects of cryptography and cryptanalysis. It is held yearly in August in Santa Barbara, California at the University of California, Santa Barbara.[14]

The first CRYPTO was held in 1981.[15] It was the first major conference on cryptology and was all the more important because relations between government, industry and academia were rather tense. Encryption was considered a very sensitive subject and the coming together of delegates from different countries was unheard-of at the time. The initiative for the formation of the IACR came during CRYPTO '82, and CRYPTO '83 was the first IACR sponsored conference.

Fellows

The International Association for Cryptologic Research (IACR) is a non-profit scientific organization dedicated to advancing research in cryptology and related fields, with a focus on the design and analysis of secure computation and communication systems resistant to adversarial threats. Founded on June 16, 1983, in , the IACR emerged from discussions initiated by cryptographer during the Crypto '82 conference, building on the momentum of the inaugural Crypto '81 event organized by figures including , , and at the . Early leadership included a board with Chaum, Diffie, and others, and the organization quickly established tax-exempt status in 1986 under president Dorothy Denning, with Ronald Rivest among its directors. Over the decades, the IACR has evolved through bylaw updates—such as introducing elected directors with three-year terms in 1990—and expanded its scope to sponsor a global array of conferences, reflecting the field's growth from theoretical foundations to practical applications in . The IACR's core activities center on fostering collaboration among researchers through flagship annual conferences like CRYPTO (held in North America), Eurocrypt (in ), and Asiacrypt (in ), alongside specialized events such as the Conference on Cryptographic Hardware and Embedded Systems (CHES), Fast Software Encryption (FSE), Public-Key Cryptography (PKC), Theory of Cryptography Conference (TCC), and Real World Crypto Symposium (RWC). These gatherings, often published in Springer's Lecture Notes in series with copyrights assigned to the IACR since 2000, provide peer-reviewed platforms for presenting cutting-edge work, with proceedings freely accessible via the IACR after a two-year embargo. Membership, open to anyone supporting the organization's aims, offers benefits including online access to publications, voting rights in elections, and eligibility for the Fellows program, which since 2002 has honored up to 0.5% of members annually for exceptional technical contributions, service, or community leadership—such as advancing cryptologic science or promoting idea exchange. Complementing its events, the IACR maintains influential publications to disseminate rapidly and rigorously. The Journal of Cryptology, launched in 1988 under editor-in-chief Ernie Brickell, serves as the premier venue for original results in all areas of modern , with an independent overseeing . Complementing this are diamond open-access journals like Transactions on Symmetric Cryptology (ToSC) for FSE submissions, Transactions on Cryptographic Hardware and Embedded Computing (TCHES) for CHES, and Communications in Cryptology for broader topics including surveys and historical pieces. The IACR ePrint Archive, established in 2000, hosts over 30,000 unreviewed preprints for quick dissemination of emerging ideas in cryptology, while the Museum of Historic Papers preserves previously unpublished foundational works. Through these efforts, the IACR remains a cornerstone of the global cryptologic community, supporting thousands of researchers in addressing challenges from quantum threats to privacy-preserving technologies.

History

Founding

The International Association for Cryptologic Research (IACR) originated from a proposal by during the CRYPTO '82 conference in , in August 1982. In his opening remarks, Chaum suggested forming an to advance cryptologic research through better coordination and communication among researchers. This initiative addressed the growing need for a dedicated body to foster collaboration in the field amid increasing interest in . An initial organizing committee was promptly assembled to develop the association, including Chaum (University of California, Santa Barbara), Henry J. Beker (Racal-Comsec Ltd., Salisbury, England), (BNR, ), Robert R. Jueneman (Satellite Business Systems, ), Ernest F. Brickell (, ), Stephen Kent (Bolt, Beranek & Newman, ), and David Kahn (, editor of Cryptologia). The committee tentatively adopted the name International Association for Cryptologic Research and began drafting a charter focused on coordinating meetings and publishing bulletins to support the community's activities. The committee's early plans included sponsoring EUROCRYPT '83 from March 21-25, 1983, in , , and CRYPTO '83 in August 1983 in the United States, with CRYPTO '83 serving as the first IACR-sponsored event. Complementing these efforts, the proceedings from CRYPTO '82 were published as Advances in Cryptology -- Proceedings of CRYPTO '82, edited by , Ronald L. Rivest, and Alan T. Sherman (ISBN 0-306-41366-3, Plenum Press).

Growth and Milestones

The International Association for Cryptologic Research (IACR) was officially established on June 16, 1983, when its articles of incorporation were filed in the state of , with the first business meeting held during the CRYPTO '83 conference. This marked the formalization of efforts initiated at CRYPTO '82 to create a dedicated for advancing cryptologic . Over the subsequent decades, IACR experienced substantial growth in membership, expanding from an initial small cadre of researchers to more than 3,000 members by 2021, reflecting the burgeoning global interest in cryptology amid advancements in computing and needs. Key milestones underscored this evolution: the launch of the Journal of Cryptology in 1988 provided a premier venue for peer-reviewed publications; the Fellows Program, approved by membership in 2002, began recognizing exceptional contributions starting with its inaugural class in 2004; the Cryptology ePrint Archive debuted in 1999 to facilitate rapid dissemination of preprints; and sponsorship of summer schools commenced in 2014, beginning with events like the SAC Summer School. The association's conference portfolio also expanded significantly during the 1990s and 2000s, incorporating regional and specialized events such as ASIACRYPT, with IACR sponsorship starting in 2000, and CHES in 1999, which addressed hardware and embedded systems . Additional sponsorships in 2004 for conferences like FSE, PKC, and TCC further diversified the offerings. Post-2000, IACR adapted to emerging field dynamics by emphasizing applied and practical implementations, evident in the proliferation of workshops on real-world systems and protocols.
