This book constitutes the thoroughly refereed post-conference proceedings of the 5th International Workshop, COSADE 2014, held in Paris, France, in April 2014. The 20 revised full papers presented together with two invited talks were carefully selected from 51 submissions and collect truly existing results in cryptographic engineering, from concepts to artifacts, from software to hardware, from attack to countermeasure.

This book constitutes the proceedings of the 14th International Workshop on Cryptographic Hardware and Embedded Systems, CHES 2012, held in Leuven, Belgium, in September 2012. The 32 papers presented together with 1 invited talk were carefully reviewed and selected from 120 submissions. The papers are organized in the following topical sections: intrusive attacks and countermeasures; masking; improved fault attacks and side channel analysis; leakage resiliency and security analysis; physically unclonable functions; efficient implementations; lightweight cryptography; we still love RSA; and hardware implementations.

This book constitutes the thoroughly refereed post-conference proceedings of the 4th International Workshop, COSADE 2013, held in Paris, France, in March 2013. The 13 revised full papers presented together with two invited talks were carefully selected from 39 submissions and collect truly existing results in cryptographic engineering, from concepts to artifacts, from software to hardware, from attack to countermeasure.

This book constitutes the thoroughly refereed post-conference proceedings of the 10th IFIP WG 8.8/11.2 International Conference on Smart Card Research and Advanced Applications, CARDIS 2011, held in Leuven, Belgium, in September 2011. The 20 revised full papers presented were carefully reviewed and selected from 45 submissions. The papers are organized in topical sections on smart cards system security, invasive attacks, new algorithms and protocols, implementations and hardware security, non-invasive attacks, and Java card security.
