Cryptographic protocols are the backbone of secure digital interactions, but achieving both security and efficiency is a challenging balancing act.  The challenge is how to minimize computational costs and reduce interaction while maintaining provable security.  This book explores cutting-edge techniques to optimize cryptographic protocols under well-established assumptions. 

The monograph focuses on secure multi-party computation, non-malleable commitments, and proof systems, presenting new constructions based on general and standard cryptographic assumptions. 

Topics and features:

This work is primarily intended for researchers, academics, and graduate students in cryptography, theoretical computer science, and cybersecurity who are interested in designing cryptographic protocols from standard and general assumptions—in particular in the setting where no setup is available.
