Four-Round Black-Box Non-Malleable Commitments from One-Way Permutations
Abstract
We construct the first four-round non-malleable commitment scheme based solely on the black-box use of one-to-one one-way functions. Prior to our work, all non-malleable commitment schemes based on black-box use of polynomial-time cryptographic primitives require more than
Note: More details on formal protocols description and full proofs added.
