Blockchain systems, as append-only ledgers, are typically associated with linearly growing
participation costs. Therefore, for a blockchain client to interact with the system (query or …

The goal of this paper is to improve the efficiency and applicability of straightline extraction
techniques in the random oracle model. Straightline extraction in the random oracle model …

Abstract With Dilithium and Falcon, NIST selected two lattice-based signature schemes
during their post-quantum standardization project. Whereas Dilithium follows the Fiat-Shamir …

An aggregate signature (AS) scheme allows an unspecified aggregator to compress many
signatures into a short aggregation. AS schemes can save storage costs and accelerate …

This work presents an approach for compressing hash-based signatures using STARKs
(Ben-Sasson et. al.'18). We focus on constructing a hash-based t-of-n threshold signature …

Authenticated Key agreement (AKA) protocol is one of the essential components for reliable
secure communication in Industrial Internet of Things (IIoT) communication model. Recently …

A great challenge for distributed payment systems is their compliance with regulations, such
as anti-money laundering, insolvency legislation, countering the financing of terrorism and …

Abstract Fischlin's transform (CRYPTO 2005) is an alternative to the Fiat-Shamir transform
that enables straight-line extraction when proving knowledge. In this work we focus on the …

Abstract The Fiat-Shamir with Aborts paradigm of Lyubashevsky has given rise to efficient
lattice-based signature schemes. One popular implementation is Dilithium, which has been …

As a momentous attribute of blockchains, the immutability ensures the integrity and
credibility of historical data, but it is inevitably abused to spread illegal content and does not …
