Group Signature with Deniability: How to Disavow a Signature [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2016 Group signatures are a class of digital signatures with enhanced privacy. By using this type of signature, a user can sign a message on behalf of a specic group without revealing his identity, but in the case of a dispute, an authority can expose the identity of the signer.

On Anonymity of Group Signatures [PDF]
, 2005 A secure group signature is required to be anonymous, that is, given two group signatures generated by two different members on the same message or two group signatures generated by the same member on two different messages, they are indistinguishable except for the group manager.

, 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.

A distributed cross-chain mechanism based on notary schemes and group signatures
Journal of King Saud University: Computer and Information Sciences, 2023 Blockchain technology has attracted significant attention since its publication. However, most existing blockchain platforms are isolated systems, which makes it difficult to exchange data among different blockchains. The industry has proposed the notary

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)

Almost Fully Secured Lattice-Based Group Signatures with Verifier-Local Revocation
Cryptography, 2020 An efficient member revocation mechanism is a desirable feature when group signature schemes are applied in practical scenarios. Revocation methods, such as verifier-local revocation (VLR), provide an efficient member revocation in applications of group ...

Unravelling the instability of mutational signatures extraction via archetypal analysis
Frontiers in Genetics, 2023 The high cosine similarity between some single-base substitution mutational signatures and their characteristic flat profiles could suggest the presence of overfitting and mathematical artefacts.
