Linkable Democratic Group Signatures [PDF]
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)

Universally Composable Group Signature Protocol [PDF]
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

AAAS: An Anonymous Authentication Scheme Based on Group Signature in VANETs
As special ad-hoc networks, vehicular ad-hoc networks (VANETs) support vehicles to communicate with each other via opportunistic wireless links. In order to protect privacy of drivers, vehicles registered in VANETs are required to authenticate and ...

Privacy-Enhancing Group Signcryption Scheme
In the last decades, several signcryption schemes have been developed for different privacy-enhancing purposes. In this paper, we propose a new privacy-enhancing group signcryption scheme that provides: unforgeability, confidentiality, ciphertext and ...

The Opening Capability for Security against Privacy Infringements in the Smart Grid Environment
It is now known that more information can be leaked into the smart grid environment than into the existing environment. In particular, specific information such as energy consumption data can be exposed via smart devices.

Group actions and higher signatures [PDF]
Let π be a nontrivial finite group and M be a closed manifold. An interesting question is whether or not M has the R -homology type of a manifold admitting a free π action. Here this problem is studied for actions

Unconditionally Secure Group Signatures
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.

Efficient Revocation in Group Signatures [PDF]
We consider the problem of revocation of identity in group signatures. Group signatures are a very useful primitive in cryptography, allowing a member of a group to sign messages anonymously on behalf of the group. Such signatures must be anonymous and unlinkable, but a group authority must be able to open them in case of dispute.

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 ...
