Cryptography has been used from time immemorial for preserving the confidentiality of
data/information in storage or transit. Thus, cryptography research has also been evolving …

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 …

We present an overview of quantum-safe cryptography (QSC) with a focus on post-quantum
cryptography (PQC) and information-theoretic security. From a cryptographic point of view …

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 …

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 …

Code-based cryptographic schemes are highly regarded among the quantum-safe
alternatives to current standards. Yet, designing code-based signatures using traditional …

Most coding theory experts date the origin of the subject with the 1948 publication of A
Mathematical Theory of Communication by Claude Shannon. Since then, coding theory has …

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

Devising efficient and secure signature schemes based on coding theory is still considered
a challenge by the cryptographic community. In this paper, we construct a signature scheme …

This paper defines a new practical construction for a code-based signature scheme. We
introduce a new protocol that is designed to follow the recent paradigm known as “Sigma …
