“Bitcoin”[1] has been a successful implementation of the concept of p2p electronic cash.
Both professionals and the general public have come to appreciate the convenient …

Ring signatures and group signatures are prominent cryptographic primitives offering a
combination of privacy and authentication. They enable individual users to anonymously …

Vehicular ad hoc networks (VANETs) is the hotspot research field of wireless mobile ad hoc
network, it provides a new opportunity to create a safe and efficient transportation …

Ring signature allows specifying a set of possible signers without revealing which member
actually produces the signature. This concept was first formalized in 2001 by Rivest, Shamir …

Traceable ring signatures, proposed at PKC'07, are a variant of ring signatures, which allow
a signer to anonymously sign a message with a tag behind a ring, ie, a group of users …

We propose unique ring signatures that simplify and capture the spirit of linkable ring
signatures. We use new techniques to provide an instantiation which can be tightly related to …

We propose a simple, general, and unified framework for constructing unique ring
signatures that simplify and capture the spirit of linkable ring signatures. The framework …

Abstract A $ k $-out-of-$ n $ ring signature is a kind of anonymous signature that can be
performed by any member in a group. This signature allows the creation of valid signatures if …

Edge computing can process data at the network edge rather than in the remote cloud. To
protect the security of the collected data, blockchain can be used in edge computing. Any …

We consider threshold ring signatures (introduced by Bresson et al. BSS02), where any tt
signers can sign a message while anonymizing themselves within a larger (size-n n) group …
