Abstract

In this paper, we investigate the discrepancy between a serial version and parallel version of zero-knowledge protocols, and clarify the information 'leaked' in the parallel version, which is not zero-knowledge unlike the case of the serial version. We consider two sides: one negative and the other positive in the parallel version of zero-knowledge protocols, especially of the Fiat-Shamir scheme.
