2020 arXiv   pre-print
In this paper, we investigate applications of one of the post-quantum signatures called Hash-Based Signature (HBS) schemes for the security of IoT devices in the quantum era.  ...  Currently, secure and reliable data communication in IoT is based on public-key cryptosystems such as Elliptic Curve Cryptosystem (ECC).  ...  with Tree (HORS-T) [40] . 1) Stateless Hierarchical Signature Schemes (HS): Some of the examples of the stateless HS scheme are SPHINCS [40] and its variants SPHINCS-Simpira [41] , Gravity-SPHINCS  ...

SPHINCS-α: A Compact Stateless Hash-Based Signature Scheme [article]

Kaiyi Zhang, Hongrui Cui, Yu Yu
2022 IACR Cryptology ePrint Archive  
Hash-based signatures offer a conservative alternative to post-quantum signatures with arguably better-understood security than other post-quantum candidates.  ...  In this paper, we introduce SPHINCS-α, a stateless hash-based signature scheme, which benefits from a twofold improvement.  ...  Introduction Hash-based signature is one of the most promising candidates for (and perhaps the most conservative approach to) post-quantum digital signatures.  ...
