2019/6/10
We present a practical digital signature scheme built from a cryptographic hash function and a hash-then-publish digital time- stamping scheme. We also provide a simple proof of existential unforgeabi...
A Blockchain-Assisted Hash-Based Signature Scheme
digital signatures hash functions public-key cryptography

2019/6/10
We present a server-supported, hash-based digital signature scheme. To achieve greater efficiency than current state of the art, we relax the security model somewhat. We postulate a set of design requ...

We analyze the concrete security of a hash-based signature scheme described in the most recent Internet Draft by McGrew, Fluhrer and Curcio. We perform this analysis in the random-oracle model, where ...
LMS vs XMSS: A comparison of the Stateful Hash-Based Signature Proposed Standards

2017/4/27
Quantum computing poses challenges to public key signature schemes as we know them today. LMS and XMSS are two hash based signature schemes that have been proposed in the IETF as quantum secure. Both ...
