A Post-Quantum UC-Commitment Scheme in the Global Random Oracle Model from Code-Based Assumptions
Abstract
In this work, we propose the first post-quantum UC-commitment scheme in the Global Random Oracle Model, where only one non-programmable random oracle is available. The security of our proposal is based on two well-established post-quantum hardness assumptions from coding theory: The Syndrome Decoding and the Goppa Distinguisher. We prove that our proposal is perfectly hiding and computationally binding. The scheme is secure against static malicious adversaries.
