Group Signatures with Selective Linkability
, 2019 Group signatures allow members of a group to anonymously produce signatures on behalf of the group. They are an important building block for privacy-enhancing applications, e.g., enabling user data to be collected in authenticated form while preserving the user’s privacy. The linkability between the signatures thereby plays a crucial role for balancing

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

GSFedSec: Group Signature-Based Secure Aggregation for Privacy Preservation in Federated Learning
Applied SciencesPrivacy must be preserved when working with client data in machine learning. Federated learning (FL) provides a way to preserve user data privacy by aggregating locally trained models without sharing the user data.

Efficient and Generalized Group Signatures [PDF]
, 1997 The concept of group signatures was introduced by Chaum et al. at Eurocrypt '91. It allows a member of a group to sign messages anonymously on behalf of the group. In case of a later dispute a designated group manager can revoke the anonymity and identify the originator of a signature.

On the Efficiency of Nonrepudiable Threshold Proxy Signature Scheme with Known Signers
, 2012 [[abstract]]In the (t,n) proxy signature scheme, the signature signed by the original signer can be signed by t or more proxy signers out of a proxy group of n proxy signers. Recently, Hsu et al.

Practically Efficient Group Signature Scheme
, 2019 Group signature schemes enable a set of members to anonymously sign data on behalf of the entire group. In order to prevent misuse, a designated group managerhas the ability to trace a given signature back to a member.

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Generalization of Proxy Signature Based on Discrete Logarithms
, 2012 [[abstract]]In the past few years, many excellent studies on proxy signature schemes have been published. Yet, traditional proxy signature schemes are mainly aimed at dealing with one or two separate proxy conditions each.

two attacks on xia-you Group Signature [PDF]
, 2002 Group signature is very important primitive in cryptography. A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion .In case of dispute, group manager can reveal the identity of the signer.

Molecular Oncology, EarlyView.In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...
