Alfredo De Santis, Giovanni Di Crescenzo, Oded Goldreich, Giuseppe Persiano#### The Graph Clustering Problem has a Perfect Zero-Knowledge Proof

Rafail Ostrovsky, Giuseppe Persiano, Ivan Visconti

One of the central questions in Cryptography today is proving security of the protocols ``on the Internet'', i.e., in a concurrent setting where there are multiple interactions between players, and where the adversary can play so called ``man-in-the-middle'' attacks, forwarding and modifying messages between two or more unsuspecting players. Indeed, ... more >>>

The input to the {\em Graph Clustering Problem}\/

consists of a sequence of integers $m_1,...,m_t$

and a sequence of $\sum_{i=1}^{t}m_i$ graphs.

The question is whether the equivalence classes,

under the graph isomorphism relation,

of the input graphs have sizes which match the input sequence of integers.
