Topics in Cryptology CT-RSA 2020

This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2020, CT-RSA 2020, held in San Francisco, CA, USA, in February 2020.

The 28 papers presented in this volume were carefully reviewed and selected from 95 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.
