This book constitutes revised selected papers from the 7th International Workshop on Constructive Side-Channel Analysis and Secure Design, COSADE 2016, held in Graz, Austria, in April 2016. The 12 papers presented in this volume were carefully reviewed and selected from 32 submissions. They were organized in topical sections named: security and physical attacks; side-channel analysis (case studies); fault analysis; and side-channel analysis (tools).

Since1994, CARDIShasbeentheforemostinternationalconferencededicatedto smart card research and applications. Every two years, the scienti?c community congregates to present new ideas and discuss recent developments with both an academicandindustrialfocus.Followingtheincreasedcapabilitiesofsmartcards anddevices, CARDIS has becomea majoreventfor the discussionofthe various issuesrelatedtotheuseofsmallelectronictokensintheprocessofhuman-machine interactions.Thescopeoftheconferenceincludesnumeroussub?eldssuchasn- working, e?cientimplementations, physicalsecurity, biometrics, andso on. This year's CARDIS was held in London, UK, on September 8-11, 2008. It was organized by the Smart Card Centre, Information Security Group of the Royal Holloway, University of London. Thepresentvolumecontainsthe21papersthatwereselectedfromthe51s- missions to the conference. The 22 members of the program committee worked hard in order to evaluate each submission with at least three reviews and agree on a high quality ?nal program. Additionally, 61 external reviewers helped the committee with their expertise. Two invited talks completed the technical p- gram. The ?rst one, given by Ram Banerjee and Anki Nelaturu, was entitled "Getting Started with Java Card 3.0 Platform." The second one, given by Aline Gouget, was about "Recent Advances in Electronic Cash Design" and was c- pleted by an abstract provided in these proceedings.

The 3-volume-set LNCS 12696 - 12698 constitutes the refereed proceedings of the 40th Annual International Conference on the Theory and Applications of Cryptographic Techniques, Eurocrypt 2021, which was held in Zagreb, Croatia, during October 17-21, 2021.The 78 full papers included in these proceedings were accepted from a total of 400 submissions. They were organized in topical sections as follows: Part I: Best papers; public-key cryptography; isogenies; post-quantum cryptography; lattices; homomorphic encryption; symmetric cryptanalysis; Part II: Symmetric designs; real-world cryptanalysis; implementation issues; masking and secret-sharing; leakage, faults and tampering; quantum constructions and proofs; multiparty computation; Part III: Garbled circuits; indistinguishability obfuscation; non-malleable commitments; zero-knowledge proofs; property-preserving hash functions and ORAM; blockchain; privacy and law enforcement.
