Workshop on Cryptographic Hardware and Embedded Systems 2011 (CHES 2011)

Nara, Japan
Wednesday September 28th - Saturday October 1st

Co-located with Non-Invasive Attack Testing Workshop (NIAT 2011)
Sunday September 25th - Tuesday September 27th, 2011

Message from the IACR Board

The submission deadline of CHES 2011 was extended to April 4th, 2011 due to the earthquake in Japan. The conference venue of CHES 2011 was moved from Tokyo to Nara, and the schedule was also changed.

Call for Papers

(in PDF format)

The focus of this workshop is on all aspects of cryptographic hardware and security in embedded systems. The workshop is a forum for new results from the research community as well as from the industry and other interested parties. Of special interest are contributions that describe new methods for secure and efficient hardware implementations, and high-speed or leak-resistant software for embedded systems, e.g. smart cards, microprocessors, DSPs, etc. The workshop aims to bridge the gap between the cryptography research community and the application areas of cryptography. All submitted papers will be reviewed.

This will be the thirteenth CHES workshop. Previous editions from 1999 to 2010 were successively held in Worcester (twice), Paris, San Francisco, Cologne, Boston, Edinburgh, Yokohama, Vienna, Washington, Lausanne, and Santa Barbara. The number of participants has grown to more than 300, with attendees coming from industry, academia, and government organizations. The topics of CHES 2011 include but are not limited to:

Cryptographic implementations
Attacks against implementations and countermeasures against these attacks
Tools and methodologies
Interactions between cryptographic theory and implementation issues

Instructions for CHES Authors

Authors are invited to submit original papers via our electronic submission system. The submission must be anonymous, with no author names, affiliations, acknowledgements, or obvious references. It should begin with a title, a short abstract, and a list of keywords. The paper should be at most 12 pages (excluding the bibliography and clearly marked appendices), and at most 16 pages in total, using at least 11-point font and reasonable margins. Submissions not meeting these guidelines risk rejection without consideration of their merits. All submissions will be blind-refereed.

Policy against double submission

Only original research contributions will be considered. Submissions which substantially duplicate work that any of the authors have published elsewhere, or have submitted in parallel to any other conferences or workshops that have proceedings or journals, will be instantly rejected . The IACR Policy on Irregular Submissions will be strictly enforced. The program committees may share information about submitted papers with other conference chairs and journal editors to help ensure the integrity of papers under consideration.


Following the success of the previous year's poster session, we invite proposals for poster presentation that relate to the topics of CHES2011 as announced in the call for paper. Proposals for poster presentations can be submitted by sending a poster title, an abstract (up to 500 words, which is about one A4 page), an author list including affiliations, and contact details (name, affiliation, phone number, and e-mail address) to the session chair (hori.y HEREAT Note that there will be no formal review process for posters. Interesting submissions dealing with a topic relevant to the CHES community can expect a fair chance of acceptance.

Call for Posters

The submission deadline was extended to Friday, August 5, 23:59 JST (UTC+9).
Acceptance notification will be sent to authors by e-mail by Friday, August 12.
