This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2022, CT-RSA 2022, held in San Francisco, CA, USA, in February 2022.* The 24 full papers presented in this volume were carefully reviewed and selected from 87 submissions. CT-RSA is the track devoted to scientific papers on cryptography, public-key to symmetric-key cryptography and from crypto-graphic protocols to primitives and their implementation security. *The conference was held as a hybrid event.

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.

You are holding the rst in a hopefully long and successful series of RSA Cr- tographers’ Track proceedings. The Cryptographers’ Track (CT-RSA) is one of the many parallel tracks of the yearly RSA Conference. Other sessions deal with government projects, law and policy issues, freedom and privacy news, analysts’ opinions, standards, ASPs, biotech and healthcare, nance, telecom and wireless security, developers, new products, implementers, threats, RSA products, VPNs, as well as cryp- graphy and enterprise tutorials. RSA Conference 2001 is expected to continue the tradition and remain the largest computer security event ever staged: 250 vendors, 10,000 visitors and 3,000 class-going attendees are expected in San Francisco next year. I am very grateful to the 22 members of the program committee for their hard work. The program committee received 65 submissions (one of which was later withdrawn) for which review was conducted electronically; almost all papers had at least two reviews although most had three or more. Eventually, we accepted the 33 papers that appear in these proceedings. Revisions were not checked on their scienti c aspects and some authors will write nal versions of their papers for publication in refereed journals. As is usual, authors bear full scienti c and paternity responsibilities for the contents of their papers.

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 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.

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.
