Quasi-Efficient Revocation of Group Signatures [PDF]
, 2003 A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion. In the event of a dispute, a designated trusted entity can reveal the identity of the signer. Group signatures are claimed to have many useful applications such as voting and electronic cash.

A New Group Signature Scheme Based on RSA Assumption
, 2013 [[abstract]]In this paper, we present a new group signature scheme based on RSA assumption. It not only achieves the same objective as the Lee-Chang scheme but also reduces the amount of computing time as compared to the Lee- Chang scheme and the Lee ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Efficient group signature scheme with revocation
Tongxin xuebao, 2016 A group signature scheme which combines the subset cover framework with Camenisch-Stadler scheme was proposed.This scheme allowed any group members’ entrance and revocation without changing other members’ secret key.Meanwhile,the scheme added a knowledge

A New Group Signature Scheme Based on the Discrete Logarithm
, 2012 [[abstract]]"Abstract: In 1998, Lee and Chang proposed an e±cient group signature scheme based on the discrete logarithm. In the Lee- Chang scheme, when the signer has been identi¯ed, the authority has to redistribute the keys of this signer and send the

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

BBS Group Signature Modification Interactive Join of Member
Безопасность информационных технологий, 2011 The article suggests a new way for ensuring digital documents security by means of a group signature scheme. Such signatures have some useful properties which are absent in common signature schemes.

Scalable Group Signatures with Revocation [PDF]
, 2012 Group signatures are a central cryptographic primitive, simultaneously supporting accountability and anonymity. They allow users to anonymously sign messages on behalf of a group they are members of. The recent years saw the appearance of several constructions with security proofs in the standard model (i.e., without appealing to the random oracle ...

A Novel ID-based Group Signature
, 2012 [[abstract]]Group signatures, first introduced by Chaum and Heyst at Eurocrypt'91, allow individual members of a group to make signatures on behalf of the group while providing the signer's anonymity.

Security Analysis of Several Group Signature Schemes [PDF]
, 2003 At Eurocrypt\u2791, Chaum and van Heyst introduced the concept of group signature. In such a scheme, each group member is allowed to sign messages on behalf of a group anonymously. However, in case of later disputes, a designated group manager can open a
