Resettable Zero-Knowledge in the Weak Public-Key Model
A new public-key model for resettable zero-knowledge (rZK) protocols, which is an extension and generalization of the upper-bounded public-key (UPK) model introduced by Micali and ...

Intrusion-Resilient Key Exchange in the Bounded Retrieval Model
Abstract. We construct an intrusion-resilient symmetric-key authenticated key exchange (AKE) protocol in the bounded retrieval model. The model employs a long shared private key to...
