Universally Composable Group Signature Protocol [PDF]
Jisuanji gongcheng, 2017 At present,most group signature is only secure in the standard alone.Its security becomes weak in multiple protocol environment.In view of this,the security of group signature protocol is studied in the multiple concurrent execution under the universally

Linkable Democratic Group Signatures [PDF]
, 2006 In a variety of group-oriented applications cryptographic primitives like group signatures or ring signatures are valuable methods to achieve anonymity of group members. However, in their classical form, these schemes cannot be deployed for applications that simultaneously require (i) to avoid centralized management authority like group manager and (ii)

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Unconditionally Secure Group Signatures
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009 A group signature scheme introduced by Chaum and Van Heyst allows a group member to sign messages anonymously on behalf of the group. However, in the case of a dispute, the identity of a signer of a group signature can be revealed only by a privileged entity, called a group manager.
