“…The most promising primitives among lattice-based cryptography, and the strongest candidates in the NIST competition, are NTRU and LWE [41], provinding the foundations for several protocols [52]- [54], [57]- [61]. Some of these lattice-based protocols have been proposed to be implemented in IoT settings [49], [54], provide data integrity for cloud-storage applications [61], to make multi-group signature schemes quantum-resistant [56], and to simplify certification management [57]. They also are the most promising candidates to construct post-quantum Blockchain and cryptocurrency schemes [20], [21], [23], [50].…”
