Recommendation for Stateful Hash-Based Signature Schemes

WebHash-based signature algorithms are comprised of two schemes, an underlying signing scheme and an extension algorithm. The former algorithm de nes the main signing procedure where a key pair can be used to sign one (Lamport [19], Winternitz one time signature scheme (WOTS), WOTS++ [8,14]) or a few WebAnalysis of a Proposed Hash-Based Signature Standard.

Hash-based signatures are attrac-tive as they can be proven secure in thestandard model (i.e., without ROs) under well-known properties of hash functions such as second preimage resistance. Unfortunately, highly efficient schemes like XMSS [22] are stateful, which seems to be problematic for practical applications [68]. crafts clip art image
