Blockchain technology provides efficient and secure solutions to various online activities by
utilizing a wide range of cryptographic tools. In this article, we survey the existing literature …

We present a new method for transforming zero-knowledge protocols in the designated
verifier setting into public-coin protocols, which can be made non-interactive and publicly …

Zero-knowledge proofs of knowledge are useful tools to design signature schemes. The
ongoing effort to build a quantum computer urges the cryptography community to develop …

The use of MPC-in-the-Head (MPCitH) based zero knowledge proofs of knowledge (ZKPoK)
to prove knowledge of a preimage of a one-way function (OWF) is a popular approach …

This work introduces a new interactive oracle proof system based on the MPC-in-the-Head
paradigm. To improve concrete efficiency and offer flexibility between computation time and …

The threat of a coming quantum computer motivates the research for new zero-knowledge
proof techniques for (or based on) post-quantum cryptographic problems. One of the few …

We introduce a new candidate post-quantum digital signature scheme from the regular
syndrome decoding (RSD) assumption, an established variant of the syndrome decoding …

The MPC-in-the-Head paradigm is a popular framework to build zero-knowledge proof
systems using techniques from secure multi-party computation (MPC). While this paradigm …

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 …

The MPC-in-the-Head paradigm is instrumental in building zero-knowledge proof systems
and post-quantum signatures using techniques from secure multi-party computation. In this …
