Title:
A Perfectly Binding Commitment Scheme Against Quantum Attacks

Authors: Zeng Bing, Chen Liang, Tang Xueming

Abstract:

It’s known that perfectly binding quantum computationally hiding commitment schemes can be constructed from any quantum one-way permutation. Since no quantum one-way permutations are known, it has been unknown by far whether we can get such a concrete commitment scheme. In this paper, we give a positive answer. Specifically, we present such a lattice-based commitment scheme, which is built from the results gained by Gentry et al.
