Group signature allows the anonymity of a real signer in a group to be revoked by a trusted party called group manager. It also gives the group manager the absolute power of controlling the formation of the group. Ring signature, on the other hand, does not allow anyone to revoke the signer anonymity, while allowing the real signer to form a group ...

A ring signature scheme enables a signer to produce a signature without revealing their identity. A verifier can verify that the ring signature was made by a ring member, but cannot identify the real signer. A convertible ring signature scheme is proposed that allows the real signer to convert a ring signature into an ordinary signature by revealing ...

A Ring Signature With Aggregation for Ensuring Privacy in Blockchain Transactions
IEEE Internet of Things JournalRing signatures are a crucial cryptographic tool underpinning blockchains and blockchain-based systems, and there are ongoing efforts to design different ring signatures to provide varying properties in a range of applications (e.g., batch verification ...

TRIFORS: LINKable Trilinear Forms Ring Signature
IACR Cryptology ePrint ArchiveWe present TRIFORS (TRIlinear FOrms Ring Signature), a logarithmic post-quantum (linkable) ring signature based on a novel assumption regarding equivalence of alternating trilinear forms.

LaRRS: Lattice-Based Revocable Ring Signature and Its Application for VANETs
IEEE Transactions on Vehicular TechnologyVehicular ad-hoc networks (VANETs) have drawn a lot of attention for their potential to improve traffic efficiency and safety. To deal with anonymous authentication and message integrity during communication, many protocols have been designed.

Nominative Signature from Ring Signature
2007Since the introduction of nominative signature (NS) in 1996, there have been a handful of schemes proposed and almost all of them have been found flawed. The only one which is secure requires multiround of communications between the nominator and the nominee for signature generation. In this paper, we propose a novel construction which is efficient and

Signatures and Semi Signatures of Abstract Witt Rings and Witt Rings of Semilocal Rings
Canadian Journal of Mathematics, 1978This paper originated in an attempt to carry over the results of [3] from the case of a field of characteristic different from two to that of semilocal rings. To carry this out, we reverse the point of view of [3] and do assume a full knowledge of the theory of Witt rings of classes of nondegenerate symmetric bilinear forms over semilocal rings as ...

Confessible Threshold Ring Signatures
2006 International Conference on Systems and Networks Communications (ICSNC'06), 2006We present two threshold ring signature schemes with different properties. One focuses on the confessibility (or signer verifiability) and the denouncibility properties. The other focuses on the threshold-confessibility. Our schemes are built on generic ring signature schemes and can be easily adapted to most existing ring signature schemes.
