Extractable Witness Encryption for KZG Commitments and Efficient Laconic OT
Abstract
We present a concretely efficient and simple extractable witness encryption scheme for KZG polynomial commitments.
It allows to encrypt a message towards a triple
Note: This revision fixes a flaw in the proof of Claim 5.
