Enhanced PKE and Time-Lock Puzzles - Asiacrypt 2021

Explore cutting-edge research in cryptography through this conference session from Asiacrypt 2021 focusing on Enhanced Public Key Encryption (PKE) and Time-Lock Puzzles. Delve into six presentations covering topics such as time-lock cryptographic assumptions in Abelian hidden-order groups, universally composable time lock encryption schemes, identity-based encryption for fair anonymity applications, simulation-based bi-selective opening security for public key encryption, key encapsulation mechanisms with tight enhanced security in multi-user settings, and hierarchical integrated signature and encryption. Gain insights from expert speakers as they discuss their latest findings and innovations in these advanced cryptographic areas. Chaired by Steven Galbraith and Yongjun Zhao, this one-hour session offers a comprehensive overview of current research trends and challenges in enhanced PKE and time-lock puzzles.
