IACR Policy on copyrights and publication

In connection with its publishing activities, it is the policy of the International Assocation for Cryptologic Research (hereinafter referred to as "IACR") to own the copyrights to all copyrightable material in its technical publications and to the individual contributions contained therein, in order to promote research in Cryptology, to protect the interests of the IACR, its authors and their employers, and, at the same time, to facilitate the appropriate archiving and distribution of this material by others. The IACR currently contracts with a commercial publisher to distribute its technical publications throughout the world, using various means such as traditional paper printing, Internet distribution, and CD-ROM media. IACR may also abstract and translate its publications, and articles contained therein, for inclusion in various compendiums and similar publications, etc. When an article is submitted to the IACR for publication, the author implicitly consents that the IACR has the rights to do all of these things.

IACR Policy on Public Dissemination

This policy applies to all material submitted to IACR: The IACR must of necessity assume that material presented at its meetings or submitted to its publications is properly available for general dissemination to the world. It is the responsibility of the authors, not the IACR, to determine whether disclosure of their material requires the prior consent of other parties and, if so, to obtain it.

Furthermore, the IACR must assume, if an author uses within his/her article material that has been previously published and/or is copyrighted by another party, that permission has been obtained for such use and that any required credit lines, copyright notices, etc., are duly noted.

IACR Obligations

In exercising its rights under this agreement, the IACR will make all reasonable efforts to act in the interests of the authors and employers as well as in its own interest. In handling third-party republication requests for an IACR work, the IACR requires that the consent of the first-named author be sought as a condition in granting republication (of a full paper) to others.; and 2) the consent of the employer be obtained as a condition in granting permission to others to reuse all or portions of a paper for promotion or marketing purposes.

Author/Company Rights

If you are employed and you prepared your paper as a part of your job, the rights to your work may rest initially with your employer. In that case, when you sign the copyright and consent to publish agreement, we assume you are authorized to do so by your employer and that your employer has consented to all the terms and conditions of this form. If not, it should be signed by someone so authorized. (See also the Public Dissemination policy above.)

Joint authorship

For jointly authored works, all the joint authors should sign, or one of the authors should sign as an authorized agent for the others. In the case of multiple authorship where one or more authors are Government employees but at least one author is not, the non-Government author should sign Part I of this copyright transfer form.


(U.S. Government employees whose work is not subject to U.S. copyright should so certify by signing Part II below.)

The undersigned hereby assigns all copyright rights in and to the above work to The International Association for Cryptologic Research, Inc. (hereinafter referred to as "IACR"). The undersigned hereby represents and warrants that the work is original and that he/she is the author of the work, except possibly for material such as text passages, figures, and data that clearly identify the original source, with permission notices from the copyright owners where required. The undersigned represents that he/she has the power and authority to make and execute this assignment.

In return for these rights, the IACR recognizes the retained rights noted in Items 1 and 4 below, and grants to the above authors and employers for whom the work may have been performed a royalty-free license to use the material as noted in Items 2, 3, and 4. Item 6 stipulates that authors and employers must seek permission to republish in cases not covered by Items 2, 3, 4, and 5.

1.  Employers (or authors) retain all proprietary rights in any process, procedure, or article of manufacture described in the work.

2.  Authors/employers may reproduce or authorize others to reproduce the above work, material extracted verbatim from the above work, or derivative works for the author's personal use or for company use provided that the source and the IACR copyright notice are indicated, that the copies are not used in any way that implies IACR endorsement of a product or service of an employer, and that the copies themselves are not offered for sale.

3.  The Author may publish his/her contribution on his/her personal Web page, subject to the restriction that it should carry a prominent copyright notice of the form "© IACR" to indicate that the copyright for this contribution is held by IACR. In addition, because IACR uses a commercial publisher to distribute its work, it is suggested that authors comply with the following two items:

  1. include a link to the primary source of publication, which at this time is
  2. delay placing their papers on their web page for a period of 12 months following the publication of the original book.

4. Authors/employers may make limited distribution of all or portions of the above work prior to publication if they inform the IACR of the nature and extent of such limited distribution prior thereto.

5. In the case of work performed under a U.S. Government contract or grant, IACR recognizes that the U.S. Government has royalty-free permission to reproduce all or portions of the above work, and to authorize others to do so, for official U.S. Government purposes only, if the contract/grant so requires. (Appropriate documentation may be attached, but IACR's Copyright Form MUST BE SIGNED.)

6. For all circumstances not covered by Items 2, 3, 4, and 5, authors/employers must request permission from the IACR to reproduce or authorize the reproduction of the work or material extracted verbatim from the work, including figures and tables.

Please note that, although authors are permitted to reuse all or portions of their IACR-copyrighted material in other works, this does not include granting third party requests for reprinting, republishing, or other types of re-use. All third party requests must be handled by the IACR.

In the event the above work is not accepted and published by the IACR or is withdrawn by the author(s) before acceptance by the IACR, this agreement becomes null and void.

PART II to be completed in case an author is a U.S. Government employee

Authors who are U.S. Government employees are not required to sign Part I of the IACR Copyright Form, but any coauthors outside the U.S. Government are required to sign Part I (see Joint authorship above). Authors whose work was performed under a U.S. Government contract or grant, but who are not Government employees, are required to sign Part I of this form. (Note: If your work was performed under U.S. Government contract but you are not a U.S. Government employee, sign Part I of this form and see item 5).

This will certify that all authors of the above work are employees of the U.S. Government and performed this work as part of their official duties and that the work is therefore not subject to U.S. copyright protection.
