Gustavo Banegas, Florian Caullery
Hash-based signatures are a type of Digital Signature Algorithms
that are positioned as one of the most solid quantum-resistant
constructions. As an example SPHINCS+, has been selected as a standard
during the NIST Post-Quantum Cryptography competition. However,
hash-based signatures suffer from two main drawbacks: signature
size and slow signing process. In this work, we give a solution to the latter
when it is used in a mobile device. We take advantage of …
