Title:
The Knowledge-of-Exponent Assumptions and 3-Round Zero-Knowledge Protocols

Authors: Mihir Bellare, Adriana Palacio

Abstract:

Hada and Tanaka showed the existence
of 3-round, negligible-error zero-knowledge arguments for NP based
on a pair of non-standard assumptions, here called KEA1 and
KEA2. In this paper we show that KEA2 is false. This renders vacuous
the results of Hada and Tanaka. We recover these results, however,
under a suitably modified new assumption called KEA3. What we
believe is most interesting is that we show that it is possible to
falsify'' assumptions like KEA2 that, due to their nature and quantifier-structure, do not lend themselves easily to efficient
falsification’’ (Naor).
