Hash function requirements for Schnorr signatures

Journal of Mathematical Cryptology, 2009
We provide two necessary conditions on hash functions for the Schnorr signature scheme to be secure, assuming compact group representations such as those which occur in elliptic curve groups. We also show, via an argument in the generic group model, that

Convertible Group Undeniable Signatures [PDF]

, 2003
Group undeniable signatures are like ordinary group signatures except that verifying signatures needs the help of the group manager. In this paper, we propose a convertible group undeniable signature scheme in which the group manager can turn all or selective signatures, which are originally group undeniable signatures, into ordinary group signatures ...

Foundations of Fully Dynamic Group Signatures [PDF]

Journal of Cryptology, 2016
AbstractGroup signatures allow members of a group to anonymously sign on behalf of the group. Membership is administered by a designated group manager. The group manager can also reveal the identity of a signer if and when needed to enforce accountability and deter abuse.

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Identification and Validation of Inflammatory Response-Related Gene Signatures to Predict the Prognosis of Neuroblastoma

International Journal of Genomics, 2022
Background. Neuroblastoma (NB) is the third most common malignant tumor in children. The inflammation is believed to be closely related to NB patients’ prognosis.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

WebRTC Swarms: Decentralized, Incentivized, and Privacy-Preserving Signaling with Designated Verifier Zero-Knowledge Authentication

Future Internet
Real-time peer-to-peer communication in web browsers typically relies on centralized signaling servers, creating single points of failure, privacy vulnerabilities, and censorship risks.

A New Secure Encryption Scheme Based on Group Factorization Problem

IEEE Access, 2019
As special types of factorization of finite groups, logarithmic signatures and covers have been used as the main components of cryptographic keys for secret key cryptosystems such as $PGM$ and public key cryptosystems like $MST_{1}$ , $MST_{2 ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Securing an Authenticated Privacy Preserving Protocol in a Group Signature Scheme Based on a Group Ring

Mathematics, 2023
Group signatures are a leading competing signature technique with a substantial amount of research. With group settings, group signatures provide user anonymity. Any group member with access to the group can generate a signature while remaining anonymous.
