Concurrently Non-Malleable Zero Knowledge in the Authenticated Public-Key Model
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 knowl...

Lower Bounds for Non-interactive Zero-Knowledge
Abstract. We establish new lower bounds and impossibility results for noninteractive zero-knowledge proofs and arguments with set-up assumptions. – For the common random string m...

Concurrent Knowledge Extraction in the Public-Key Model
Knowledge extraction is a fundamental notion, modeling machine possession of values (witnesses) in a computational complexity sense and enabling one to argue about the internal st...

Improved Setup Assumptions for 3-Round Resettable Zero Knowledge
In the bare public-key model, introduced by Canetti et al. [STOC 2000], it is only assumed that each verifier deposits during a setup phase a public key in a file accessible by a...

Multi-signatures in the plain public-Key model and a general forking lemma
A multi-signature scheme enables a group of signers to produce a compact, joint signature on a common document, and has many potential uses. However, existing schemes impose key s...
