Abstract
A zero-knowledge proof (ZKP) is an interactive
proof that allows a prover to prove the knowledge of a
secret to a verifier without revealing it. ZKPs are
powerful tools to deal with critical applications in
security e-commerce. Existing ZKPs are iterative in
nature; their protocols require multiple communica-
tion rounds. The cost of iteration makes ZKPs unsuit-
able in practice. We propose a new protocol that meets
all the requirements of ZKPs, yet runs in one round.
The new approach substantially reduces computation
and communications costs. It makes ZKPs more
