We construct constant round ZKIPs for any NP language, under the sole assumption that oneway functions exist. Under the stronger Certified Discrete Log assumption, our construction yields perfect zero knowledge protocols. Our protocols rely on two novel ideas: One for constructing commitment schemes, the other for constructing subprotocols which are not known to be zero knowl- edge, yet can be proven not to reveal useful information.
