Title:
Hash-Based Blind Signatures: First Steps
Authors: Javier Herranz, Hugo Louiso
Abstract:Hash-based signatures are a strong candidate for post-quantum scenarios requiring authentication and integrity. Their security relies only on (well-studied) properties of hash functions, so they may be thought as being more robust than other schemes that (today) resist quantum attacks, like those based on lattices, coding or isogenies.
Recent works are also studying hash-based signature schemes with additional properties, like group, ring, threshold, or aggregate signature schemes. In this work we do the same for the important case of blind signatures. We describe a possible hash-based instantiation of Fischlin’s generic scheme, we motivate our choices and we finally give some benchmarks for running times and memory requirements, resulting from our C implementation.
