I listened to a talk on NIZK a while ago and vaguely remembered the speaker mentioned something like - A scheme that is statistically sound and computationally ZK in common reference string model could become computationally sound and statistically ZK in common random string model.
I couldn’t remember the exact talk and speaker, but I’m wondering whether this kind of duality is common in CRS constructions, and if so, how do we convert a scheme in common reference string model into one in common random string model?
Thanks!
