No refunds will be made for cancellations after this date. A copy of the electronic proceedings will be made available to those who registered but were unable to attend.

Student speaker

Any student presenting a paper at CHES will get his or her registration fee waived thanks to the IACR Cryptography Research Fund for Students. If you are a student speaker, please contact the general chairs before online registration.

Student stipends

Due to the generous support of our sponsors we are able to offer free registration and possibly support for travel and accommodation to a number of students and young researchers who would otherwise find it hard to attend the conference.

If you wish to apply for a student stipend please email the general chairs by July 31st 2015. The email should include your resume and a short motivation letter. Please ask your PhD supervisor or some of your professors to contact the general chairs and provide a letter of recommendation.
