Abstract
In this paper we classify several group-theoretic computational problems into the classes PZK and SZK (problems with perfect/statistical zero-knowledge proofs respectively). Prior to this, these problems were known to be in AM ∩ coAM. As PZK ⊆ SZK ⊆ AM ∩ coAM, we have a tighter upper bound for these problems.
Part of the work done was during visits to Berlin supported by a DST-DAAD project.
