Concurrent Knowledge Extraction in the Public-Key Model
Knowledge Extraction Public-Key Model
2010/2/20
Knowledge extraction is a fundamental notion, modeling machine possession of values (wit-
nesses) in a computational complexity sense and enabling one to argue about the internal state
of a party in...
New Notions of Soundness and Simultaneous Resettability in the Public-Key Model
rZK arguments PRF
2009/4/16
In this paper, some new notions of soundness in public-key model are presented. We clarify the relationships among our new notions of soundness and the original 4 soundness notions presented by Micali...
Concurrent/Resettable Zero-Knowledge With Concurrent Soundness in the Bare Public-Key Model and Its Applications
concurrent knowledge-extraction concurrent non-malleability concurrent/resettable zero-knowledge
2009/4/10
In this work, we investigate concurrent knowledge-extraction (CKE) and concurrent non-malleability
(CNM) for concurrent (and stronger, resettable) ZK protocols in the bare public-key model.
We formu...
Concurrently Non-Malleable Zero Knowledge in the Authenticated Public-Key Model
Zero-Knowledge Protocols Concurrently Non-Malleability Public-Key Models
2008/12/17
We consider a type of zero-knowledge protocols that are of interest for their practical applications within networks
like the Internet: efficient zero-knowledge arguments of knowledge that remain se...
Resettable Zero Knowledge in the Bare Public-Key Model under Standard Assumption
Resettable Zero Knowledge Concurrent Soundness Bare Public-Key Model Resettably sound Zero Knowledge
2008/12/5
In this paper we resolve an open problem regarding resettable zero knowledge
in the bare public-key (BPK for short) model: Does there exist constant
round resettable zero knowledge argument with con...
