Having been established in 1999, the Cryptographic Hardware and Embedded Systems (CHES) conference is the
premier venue for research on both 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.
CHES 2021 will take place in
Beijing, China on
September 12–15, 2021 (tentative).
The conference website is accessible at
The scope of CHES is intentionally diverse, meaning we solicit submission of papers on topics including, but not
limited to, the following:
Cryptographic processors and co-processors
True and pseudorandom number generators
Physical unclonable functions (PUFs)
Efficient software implementations
Attacks against implementations, and countermeasures:
Side-channel attacks and countermeasures
Micro-architectural side-channel attacks
Fault attacks and countermeasures
Hardware tampering and tamper-resistance
White-box cryptography and code obfuscation
Hardware and software reverse engineering
Tools and methodologies:
Computer-aided cryptographic engineering
Verification methods and tools for secure design
Domain-specific languages for cryptographic systems
Metrics for the security of embedded systems
Secure programming techniques
FPGA design security
Interactions between cryptographic theory and implementation issues:
New and emerging cryptographic algorithms and protocols targeting embedded devices
Special-purpose hardware for cryptanalysis
Leakage resilient cryptography
Cryptography and security for the Internet of Things (RFID, sensor networks, smart devices, smart meters, etc.)
Hardware IP protection and anti-counterfeiting
Reconfigurable hardware for cryptography
Smartcard processors, systems and applications
Security for cyberphysical systems (home automation, medical implants, industrial--control systems, etc.)
Secure storage devices (memories, disks, etc.)
Technologies and hardware for content protection
Trusted computing platforms
Hybrid Publication Model
As of 2018, CHES has moved to an open-access journal/conference hybrid model. Following the success of similar
initiatives at analogous events such as FSE, this decision was made (by the CHES steering committee) as a means
of improving review and publication quality while retaining the highly successful, community-focused event.
A comprehensive set of FAQs relating to the model can be found via the TCHES website at
https://tches.iacr.org. In summary:
Submitted papers will undergo a journal-style review process, with accepted papers published by
Ruhr University Bochum in an issue of the journal IACR Transactions on Cryptographic Hardware and Embedded Systems (TCHES).
Since it has Gold Open Access status, all TCHES papers are immediately and freely available.
The annual CHES conference consists of presentations for each paper published in the associated issues of
TCHES, plus invited talks and a range of additional and social activities.
TCHES has four submission deadlines per year; all papers accepted for publication in TCHES between 15 July
of year n–1 and 15 July of year n will be presented at CHES of year n.
