This book constitutes the refereed proceedings of the Second International Conference on Security, Privacy and Applied Cryptography Engineering held in Chennai, India, in November 2012.The 11 papers presented were carefully reviewed and selected from 61 submissions. The papers are organized in topical sections on symmetric-key algorithms and cryptanalysis, cryptographic implementations, side channel analysis and countermeasures, fault tolerance of cryptosystems, physically unclonable functions, public-key schemes and cryptanalysis, analysis and design of security protocol, security of systems and applications, high-performance computing in cryptology and cryptography in ubiquitous devices.

CHES 2009, the 11th workshop on Cryptographic Hardware and Embedded Systems, was held in Lausanne, Switzerland, September 6–9, 2009. The wo- shop was sponsored by the International Association for Cryptologic Research (IACR). The workshop attracted a record number of 148 submissions from 29 co- tries, of which the Program Committee selected 29 for publication in the wo- shop proceedings, resulting in an acceptance rate of 19.6%, the lowest in the history of CHES. The review process followed strict standards: each paper - ceived at least four reviews, and some asmanyaseightreviews.Membersofthe Program Committee were restricted to co-authoring at most two submissions, and their papers were evaluated by an extended number of reviewers. The ProgramCommittee included 53 members representing 20 countries and?ve continents. These members were carefully selected to represent academia, industry, and government, as well as to include world-class experts in various research?elds of interest toCHES. The Program Committee was supported by 148 external reviewers. The total number of people contributing to the - view process, including Program Committee members, external reviewers, and Program Co-chairs, exceeded 200. The papers collected in this volume represent cutting-edge worldwide - search in the rapidly growing and evolving area of cryptographic engineering.

This book constitutes the refereed proceedings of the 10th Interntaional Workshop on Cryptographic Hardware and Embedded Systems, CHES 2008, held in Washington, D.C., USA, during August 10-13, 2008. The book contains 2 invited talks and 27 revised full papers which were carefully reviewed and selected from 107 submissions. The papers are organized in topical sections on side channel analysis, implementations, fault analysis, random number generation, and cryptography and cryptanalysis.

CHES2007,theninthworkshoponCryptographicHardwareandEmbeddedS- tems, was sponsored by the International Association for Cryptologic Research (IACR) and held in Vienna, Austria, September 10–13, 2007. The workshop - ceived 99 submissions from 24 countries, of which the Program Committee (39 members from 15 countries) selected 31 for presentation. For the?rst time in the history of CHES, each submission was reviewed by at least four reviewers instead of three (and at least?ve for submissions by PC members, those now being limited to two per member) and many submitted papers have received plenty of extra reviews (some papers received up to nine reviews), thus totalling the unprecedented record of 483 reviews overall.

The wide diversity of subjects appearing in these proceedings covers virtually all related areas and shows our e?orts to extend the scope of CHES more than usual.

Selecting from so many good worksis no easy task and our deepest thanks go to the members of the Program Committee for their involvement, excellence, and team spirit. We are grateful to the numerous external reviewers listed below for their expertise and assistance in our deliberations.
