This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2006, CT-RSA 2006, held in San Jose, CA, USA in February 2006. The book presents 24 papers organized in topical sections on attacks on AES, identification, algebra, integrity, public key encryption, signatures, side-channel attacks, CCA encryption, message authentication, block ciphers, and multi-party computation.

This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2008, CT-RSA 2008, held in San Francisco, CA, USA in April 2008. The 26 revised full papers presented together with the abstract of 1 invited talk were carefully reviewed and selected from 95 submissions. The papers are organized in topical sections on hash function cryptanalysis, cryptographic building blocks, fairness in secure computation, message authentication codes, improved aes implementations, public key encryption with special properties, side channel cryptanalysis, cryptography for limited devices, invited talk, key exchange, cryptanalysis, and cryptographic protocols.

This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2007, CT-RSA 2007, held in San Francisco, CA, USA in February 2007. The 25 revised full papers presented together with two invited papers were carefully reviewed and selected from 73 submissions. The papers are organized in topical sections.

The 2009 RSA conference was held in San Francisco, USA, during April 20-24. The conference is devoted to security-related topics and, as part of this, hosts a distinguished track for cryptographic research. Since 2001 the proceedings of this Cryptographers' Track (CT-RSA) have been published in the series Lecture Notes in Computer Science of Springer. The proceedings of CT-RSA 2009 contain 31 papers selected from 93 s- missions, covering a wide variety of cryptographic areas. Each submission was anonymizedforthereviewingprocessandwasassignedto atleastthreeofthe25 ProgramCommittee members. Submissions co-authoredby committee members were assigned to at least ?ve members. After carefully considering more than 15,000 lines (more than 100,000 words) of reviews and online discussions, the committeeselected31submissionsforacceptance. Theprogramalsoincludedan invited talk by Kenny Paterson entitled “Cryptography and Secure Channels. ” Iwouldliketothankalltheauthorswhosubmittedpapers. Iamalsoindebted to the Program Committee members and all external reviewers for their vol- tary work. The committee's work was tremendously simpli?ed by Shai Halevi's submission software and his support. I would also like to thank the CT-RSA Steering Committee for electing me as Chair, and all the people from the RSA conference team for their support, especially Bree LaBollita.

This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2010, CT-RSA 2010, held in San Francisco, CA, USA in April 2010. The 25 revised full papers presented together with 1 invited lecture were carefully reviewed and selected from 94 submissions. The papers are organized in topical sections on public-key cryptography, side-channel attacks, cryptographic protocols, cryptanalysis, and symmetric cryptography.

This book constitutes the refereed proceedings of the Cryptographers' Track at the RSA Conference 2012, CT-RSA 2012, held in San Francisco, CA, USA, in February/March 2012. The 26 revised full papers presented were carefully reviewed and selected from 113 submissions. The papers are organized in topical sections on side channel attacks, digital signatures, public-key encryption, cryptographic protocols, secure implementation methods, symmetric key primitives, and secure multiparty computation.

This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2017, CT-RSA 2017, held in San Francisco, CA, USA, in February 2017. The 25 papers presented in this volume were carefully reviewed and selected from 77 submissions. CT-RSA has become a major publication venue in cryptography. It covers a wide variety of topics from public-key to symmetric key cryptography and from cryptographic protocols to primitives and their implementation security. This year selected topics such as cryptocurrencies and white-box cryptography were added to the call for papers.
