Interleaved Zero-Knowledge in the Public-Key Model.

Revisions: 1 , Comments: 1

We introduce the notion of Interleaved Zero-Knowledge (iZK),
a new security measure for cryptographic protocols which strengthens
the classical notion of zero-knowledge, in a way suitable for multiple
concurrent executions in an asynchronous environment like the internet.
We prove that iZK protocols are robust: they are ``parallelizable'',
and ... more >>>

Resettable Zero-Knowledge.

Revisions: 1


We introduce the notion of Resettable Zero-Knowledge (rZK),
a new security measure for cryptographic protocols
which strengthens the classical notion of zero-knowledge.
In essence, an rZK protocol is one that remains zero knowledge
even if an adeversary can interact with the prover many times, each
time ... more >>>
