Although they have been studied for a long time, distributed signature protocols have
garnered renewed interest in recent years in view of novel applications to topics like …

In this paper, we propose DiLizium: a new lattice-based two-party signature scheme. Our
scheme is constructed from a variant of the Crystals-Dilithium post-quantum signature …

Zero knowledge interactive proof systems are a fundamental tool in modern cryptology,
forming the foundation of many efficient cryptographic primitives, such as identification …

Multisignatures enable multiple users to sign a message interactively. Many instantiations
are proposed for multisignatures, however, most of them are quantum-insecure, because …
