We introduce SPHINCS+, a stateless hash-based signature framework. SPHINCS+ has
significant advantages over the state of the art in terms of speed, signature size, and …

We present several optimizations to SPHINCS, a stateless hash-based signature scheme
proposed by Bernstein et al. in (2015): PORS, a more secure variant of the HORS few-time …

This work introduces XMSS-T, a new stateful hash-based signature scheme with tight
security. Previous hash-based signatures are facing a loss of security, linear in performance …

We present W-OTS+, a Winternitz type one-time signature scheme (W-OTS). We prove that
W-OTS+ is strongly unforgeable under chosen message attacks in the standard model. Our …

In this work we show a general construction for transforming any chameleon hash function to
a strongly unforgeable one-time signature scheme. Combined with the result of [Bellare and …

Signature schemes based on the MPC-in-the-head approach (MPCitH) have either been
designed by taking a proof system and selecting a suitable symmetric-key primitive (Picnic …

This work introduces Banquet, a digital signature scheme with post-quantum security,
constructed using only symmetric-key primitives. The design is based on the MPC-in-head …

Zero-knowledge (ZK) applications form a large group of use cases in modern cryptography,
and recently gained in popularity due to novel proof systems. For many of these …

Abstract We introduce Multi Tree XMSS (XMSS MT), a hash-based signature scheme that
can be used to sign a virtually unlimited number of messages. It is provably forward and …

We show that the Winternitz one-time signature scheme is existentially unforgeable under
adaptive chosen message attacks when instantiated with a family of pseudorandom …
