Conference on

Cryptographic Hardware

and Embedded Systems

The annual Conference on Cryptographic Hardware and Embedded Systems (CHES) is the premier venue for research on design and analysis of cryptographic hardware and software implementations. As an area conference of the International Association for Cryptologic Research (IACR), CHES bridges the cryptographic research and engineering communities, and attracts participants from academia, industry, government and beyond.

Dear CHES community,

Due to the corona virus pandemic, its consequences and the uncertainty regarding when it will be under control and eventually stopped, the CHES Steering Committee in coordination with the local organizers for 2020 and 2021 as well as with the IACR Board of Directors decided today to turn CHES 2020 into a virtual event and to postpone the schedule for physical conferences by one year. That means:

For contractual and planning purposes a decision had to be made now. We are convinced that there is currently too much uncertainty for an attempt to postpone CHES 2020 by a couple of weeks or months.

Please note that the TCHES publication cycle is not affected by this decision.

We apologize for any inconvenience caused and hope that we can all enjoy CHES 2021 in Beijing under normal conditions. In the meantime, please stay tuned for updates concerning the first virtual CHES 2020 in the next weeks!
