Shared Dynamic Data Audit Supporting Anonymous User Revocation in Cloud Storage
IEEE Access, 2019 Collusion between revoked users and cloud service providers can pose a threat to the security of cloud storage data. If the original legitimate users cannot be revoked securely, it will lead to the leakage of shared data, thus affecting the security of ...

AAAS: An Anonymous Authentication Scheme Based on Group Signature in VANETs
IEEE Access, 2020 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 ...

The Novikov conjecture on Cheeger spaces [PDF]
, 2016 We prove the Novikov conjecture on oriented Cheeger spaces whose fundamental group satisfies the strong Novikov conjecture. A Cheeger space is a stratified pseudomanifold admitting, through a choice of ideal boundary conditions, an L2-de Rham cohomology ...

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

Privacy-Enhancing Group Signcryption Scheme
IEEE Access, 2021 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 ...

Group actions and higher signatures [PDF]
Proceedings of the National Academy of Sciences, 1985 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 that are “homologically trivial.” If π 1
