Short Linkable Ring Signatures Revisited

2006
Ring signature is a group-oriented signature in which the signer can spontaneously form a group and generate a signature such that the verifier is convinced the signature was generated by one member of the group and yet does not know who actually signed.

Forward-Secure Linkable Ring Signatures

2018
We present the first linkable ring signature scheme with both unconditional anonymity and forward-secure key update: a powerful tool which has direct applications in elegantly addressing a number of simultaneous constraints in remote electronic voting.

Injectable enzymatically cross linkable hydrogels

Osteoarthritis and cartilage, 2015
Purpose: Focal cartilage defects as a consequence of trauma are a major risk factor for the development of early onset osteoarthritis. These defects still pose a largely unresolved problem for the treating physician. Previously, we have developed an injectable in situ gelating hydrogel that can be applied in an arthroscopic procedure to fill up ...

Many-Time Linkable Ring Signatures

Linkable ring signatures (Liu et al., ACISP’04) is a ring signature scheme with a linking mechanism for detecting signatures from the same signer. This functionality has found many practical applications in electronic voting, cryptocurrencies, and whistleblowing systems. However, existing linkable ring signature schemes impose a fundamental limitation:

Ring Signature with Designated Linkability

2006
Ring signatures enable a user to sign a message so that a ring of possible signers is identified, without revealing exactly which member of that ring actually generated the signature. This concept has been used to construct new cryptographic applications, such as designated signatures, concurrent signatures, etc.

Certificate Based (Linkable) Ring Signature

2007
In this paper, we propose a new notion called Certificate Based Ring Signature (CBRS) that follows the idea of Certificate Based Encryption (CBE) presented by Gentry in EuroCrypt 2003. It preserves the advantages of CBE such as implicit certificate and no private key escrow.

Separable Linkable Threshold Ring Signatures

2004
A ring signature scheme is a group signature scheme with no group manager to setup a group or revoke a signer. A linkable ring signature, introduced by Liu, et al. [20], additionally allows anyone to determine if two ring signatures are signed by the same group member (a.k.a. they are linked). In this paper, we present the first separable linkable ring

Exploring Linkability of User Reviews

2012
Large numbers of people all over the world read and contribute to various review sites. Many contributors are understandably concerned about privacy in general and, specifically, about linkability of their reviews (and accounts) across multiple review sites. In this paper, we study linkability of community-based reviewing and try to answer the question:

Distributed Workflow upon Linkable Coordination Artifacts

2006
Coordination infrastructures can be used for the general-purpose support of WfMSs (workflow management systems). Suitably-expressive coordination artifacts can be specialised as workflow engines, encapsulating workflow rules expressed in terms of coordination laws. In this paper, we focus on the issue of inter-organisational workflow (IOW), and show

Linkability in Countable-Like Webs

1990
A web is a triple (G, A, B), where G is a directed graph and A, B ⊆ V(G). It is called linkable if there exists a family of disjoint paths from all of A into B. It is countable-like if (G, A’, B) is linkable for some subset A’ of A such that A\A’ is countable. In [1] a sufficient condition was given for linkability in countable webs.
