This book constitutes the refereed proceedings of the 17th International Workshop on
Cryptographic Hardware and Embedded Systems CHES 2015 held in Saint Malo France in
September 2015. The 34 full papers included in this volume were carefully reviewed and selected
from 128 submissions. They are organized in the following topical sections: processing
techniques in side-channel analysis cryptographic hardware implementations homomorphic
encryption in hardware side-channel attacks on public key cryptography cipher design and
cryptanalysis true random number generators and entropy estimations side-channel analysis and
fault injection attacks higher-order side-channel attacks physically unclonable functions and
hardware trojans side-channel attacks in practice and lattice-based implementations.
