This volume contains the workshopproceedings of the accompanying workshops of the 14th Financial Cryptograpy and Data Security International Conference 2010, held on Tenerife, Canary Islands, Spain, January 25-28, 2010. FinancialCryptographyandData Securityis a majorinternationalforumfor research, advanced development, education, exploration, and debate regarding information assurance, with a speci?c focus on commercial contexts. The c- ference covers all aspects of securing transactions and systems and especially encourages original work focusing on both fundamental and applied real-world deployments on all aspects surrounding commerce security. Three workshops were co-located with FC 2010: the Workshop on Real-Life CryptographicProtocolsandStandardization(RLCPS),theWorkshoponEthics in Computer Security Research (WECSR), and the Workshop on Lightweight Cryptography for Resource-Constrained Devices (WLC). Intimate and colorful by tradition, the high-quality program was not the only attraction of FC. In the past, FC conferences have been held in highly research-synergistic locations such as Tobago, Anguilla, Dominica, Key West, Guadelupe, Bermuda, the Grand Cayman, and Cozumel Mexico. 2010 was the ?rst year that the conference was held on European soil, in the Spanish Canary Islands, in Atlantic waters, a few miles across Morocco. Over 100 researchers from more than 20 countries were in attendance.

Cryptography is an area that traditionally focused on secure communication, authentication and integrity. In recent times though, there is a wealth of novel fine-tuned cryptographic techniques that sprung up as cryptographers focused on the specialised problems that arise in digital content distribution. These include fingerprinting codes, traitor tracing, broadcast encryption and others. This book is an introduction to this new generation of cryptographic mechanisms as well as an attempt to provide a cohesive presentation of these techniques.

"Encryption for Digital Content" details the subset cover framework (currently used in the AACS encryption of Blu-Ray disks), fingerprinting codes, traitor tracing schemes as well as related security models and attacks. It provides an extensive treatment of the complexity of the revocation problem for multi-receiver (subscriber) encryption mechanisms, as well as the complexity of the traceability problem. Pirate evolution type of attacks are covered in depth. This volume also illustrates the manner that attacks affect parameter selection, and how this impacts implementations. The authors gratefully acknowledge the support of the National Science Foundation under Grant No. 0447808.

This book constitutes the refereed proceedings of the 13th International Conference on Cryptology and Network Security, CANS 2014, held in Heraklion, Creete, Greece, in October 2014. The 25 revised full papers presented together with the abstracts of 3 invited talks were carefully reviewed and selected from 86 submissions. The papers cover topics of interest such as encryption; cryptanalysis; malware analysis; and privacy and identification systems as well as various types of network protocol design and analysis work.

This volume constitutes the thoroughly refereed post-conference proceedings of the Third Conference on E-Voting and Identity, VOTE-ID 2011, held in Tallinn, Estonia, in September 2011. The 15 revised full papers presented were carefully reviewed and selected from 33 submissions. They are organized in topical sections on Norwegian internet voting, voting systems I and II, pret a voter and trivitas, and experiences.

Here are the refereed proceedings of the 9th International Conference on Theory and Practice in Public-Key Cryptography, PKC 2006, held in New York City in April 2006. The 34 revised full papers presented are organized in topical sections on cryptanalysis and protocol weaknesses, distributed crypto-computing, encryption methods, cryptographic hash and applications, number theory algorithms, pairing-based cryptography, cryptosystems design and analysis, signature and identification, authentication and key establishment, multi-party computation, and PKI techniques.

The two-volume set LNCS 12110 and 12111 constitutes the refereed proceedings of the 23rd IACR International Conference on the Practice and Theory of Public-Key Cryptography, PKC 2020, held in Edinburgh, UK, in May 2020. The 44 full papers presented were carefully reviewed and selected from 180 submissions. They are organized in topical sections such as: functional encryption; identity-based encryption; obfuscation and applications; encryption schemes; secure channels; basic primitives with special properties; proofs and arguments; lattice-based cryptography; isogeny-based cryptography; multiparty protocols; secure computation and related primitives; post-quantum primitives; and privacy-preserving schemes.

This book constitutes the thoroughly refereed post-conference proceedings of the 21st International Conference on Financial Cryptography and Data Security, FC 2017, held in Sliema, Malta, in April 2017. The 30 revised full papers and 5 short papers were carefully selected and reviewed from 132 submissions. The papers are grouped in the following topical sections: Privacy and Identity Management; Privacy and Data Processing; Cryptographic Primitives and API's; Vulnerabilities and Exploits; Blockchain Technology; Security of Internet Protocols; Blind signatures; Searching and Processing Private Data; Secure Channel Protocols; and Privacy in Data Storage and Retrieval.
