Topics in cryptology -- CT-RSA 2018 : the Cryptographers' Track at the RSA Conference 2018, San Francisco, CA, USA, April 16-20, 2018, Proceedings

This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2018, CT-RSA 2018, held in San Francisco, CA, USA, in March 2018. The 26 papers presented in this volume were carefully reviewed and selected from 79 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.
