This book constitutes the refereed proceedings of the Cryptographer''s Track at the RSA Conference 2019, CT-RSA 2019, held in San Francisco, CA, USA, in March 2019.

The 28 papers presented in this volume were carefully reviewed and selected from 75 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.

This book constitutes the thoroughly refereed postproceedings of the 10th Annual International Workshop on Selected Areas in Cryptography, SAC 2003, held in Ottawa, Canada, in August 2003.

The 25 revised full papers presented were carefully selected from 85 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on elliptic and hyperelliptic curves, side channel attacks, security protocols and applications, cryptanalysis, cryptographic primitives, stream ciphers, and efficient implementations.
