Concurrent/Resettable Zero-Knowledge With Concurrent Soundness in the Bare Public-Key Model and Its Applications.
Yunlei Zhao · 2003
In this paper, we present both practical and general 4-round concurrent and resettable zeroknowledge arguments with concurrent soundness in the bare public-key (BPK) model. To our knowledge, our result is the first work that achieves concurrent soundness for ZK protocols in the BPK model and stands for the current state-of-the-art of concurrent zero-knowledge with setup assumptions.
