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)

Attribute-based signatures with user-controlled linkability [PDF]
, 2014 In this paper, we introduce Attribute-Based Signatures with User-Controlled Linkability (ABS-UCL). Attribute-based signatures allow a signer who has enough credentials/attributes to anonymously sign a message w.r.t.

On Design of Single-Layer and Multilayer Code-Based Linkable Ring Signatures
IEEE Access, 2020 In this paper, we present an effective code-based linkable ring signature scheme based on Borromean ring signature. The security of the scheme is based on the hardness of Syndrome Decoding problem, General Syndrome Decoding problem and Codeword Finding ...

On Profile Linkability despite Anonymity in Social Media Systems [PDF]
, 2016 A number of works have recently shown that the privacy offered by pseudonymous identities on social media systems like Twitter or Reddit is threatened by cross-site identity linking attacks.

Linkable Ring Signatures：Technological Evolution, Comparative Analysis of Core Variants, and Application Frontier Survey [PDF]
Jisuanji kexue yu tansuoLinkable ring signatures (LRS), a key variant of ring signatures, enables the detection of multiple signatures from the same signer through a built-in linkability mechanism while preserving signer anonymity, thereby balancing privacy and accountability ...

Anonymous attestation with user-controlled linkability [PDF]
International Journal of Information Security, 2013 This paper is motivated by the observation that existing security models for direct anonymous attestation (DAA) have problems to the extent that insecure protocols may be deemed secure when analysed under these models. This is particularly disturbing as DAA is one of the few complex cryptographic protocols resulting from recent theoretical advances ...

On the Linkability of Some Group Signature Schemes [PDF]
Informatica, 2003 Summary: A group signature scheme is a digital signature scheme that allows a group member to sign messages anonymously on behalf of the group. Recently, Tseng and Jan proposed two group signature schemes based on self-certified and ID-based public keys respectively. However, these two schemes were shown to be insecure.

CryptographyRing signatures are widely used in e-voting, anonymous whistle-blowing systems, and blockchain transactions. However, due to the anonymity of ring signatures, a signer can sign the same message multiple times, potentially leading to repeated voting or ...
