Group-Signature and Group Session Key Combined Safety Message Authentication Protocol for VANETs
IEEE Access, 2019 Anonymous authentication has significant contribution to privacy protection in safety message dissemination for Vehicular Ad Hoc Networks (VANETs); however, it suffers from heavy workload of vehicle revocation check and message signature verification ...

Reconstruction for the Signature of a Rough Path [PDF]
, 2016 Recently it was proved that the group of rough paths modulo tree-like equivalence is isomorphic to the corresponding signature group through the signature map S (a generalized notion of taking iterated path integrals).

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.

The mapping class group and the Meyer function for plane curves [PDF]
, 1998 For each d>=2, the mapping class group for plane curves of degree d will be defined and it is proved that there exists uniquely the Meyer function on this group.

System for Anonymous Data Collection Based on Group Signature Scheme
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 This paper deals with an anonymous data collection in the Internet of Things (IoT). the privacy and anonymity of the data source is important for many IoT applications, such as in agriculture, health, and automotive.

A Privacy-Preserving Key Management Scheme with Support for Sybil Attack Detection in VANETs
Sensors, 2021 Vehicular ad hoc networks (VANETs) face two important and conflicting challenges with regards to security: preserve the privacy of vehicles in order to prevent malicious entities from tracking users and detect and remove bad actors that attempt to game ...

On the origin of the difference between time and space [PDF]
, 2004 We suggest that the difference between time and space is due to spontaneous symmetry breaking. In a theory with spinors the signature of the metric is related to the signature of the Lorentz-group.

Group–Proxy Signature Scheme: A Novel Solution to Electronic Cash
Journal of Intelligent Systems, 2013 Proxy signature and group signature are two basic cryptographic primitives. Due to their valuable characteristics, many schemes have been put forward independently and they have been applied in many practical scenarios up to the present.

SRCPR: SignReCrypting Proxy Re-Signature in Secure VANET Groups
IEEE Access, 2018 Vehicular Ad hoc Network is an emerging area as a key component of the intelligent transport system. Despite the immense researches going on in this area, it is yet to be deployed at its full scale due to lack of trust, safety, and confidentiality in the

, 2012 We initiate the study of unique group signature such that signatures of the same message by the same user will always have a large common component (i.e., unique identifier). It enables an efficient detection algorithm, revealing the identities of illegal users, which is fundamentally different from previous primitives.
