Two-Round Multi-Signatures from Okamoto Signatures
Mathematics, 2023 Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain

The monodromy pairing and discrete logarithm on the Jacobian of finite graphs
Journal of Mathematical Cryptology, 2010 Every graph has a canonical finite abelian group attached to it. This group has appeared in the literature under a variety of names including the sandpile group, critical group, Jacobian group, and Picard group.

Computation of discrete logarithms in prime fields [PDF]
Designs, Codes and Cryptography, 1991 The presumed difficulty of computing discrete logarithms in finite fields is the basis of several popular public key cryptosystems. The secure identification option of the Sun Network File System, for example, uses discrete logarithms in a field GF(p) with p a prime of 192 bits.

A new directed signature scheme on a general linear group over a group ring
Journal of Innovative Applied Mathematics and Computational Sciences, 2023 In this work, we propose a new directed digital signature scheme over a group ring whose security relies on the hardness of the discrete logarithm problem and the factorization search problem. This scheme is efficient as it requires very few operations

Advanced Healthcare Materials, EarlyView.This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...
