A certificateless ring signature scheme based on lattice
Concurrency and Computation, 2022For the problems that ring signature needs key escrow, has some security risks, and cannot avoid malicious key generation center (KGC) in the post‐quantum era, we design a certificateless ring signature scheme based on lattice (L‐CRSS).

Proxy signatures have been used to enable the transfer of digital signing power within some context and ring signatures can be used to provide the anonymity of a signer. By combining the functionalities of proxy signatures and ring signatures, this paper introduces a new concept, named ring proxy signature, which is a proxy signature generated by an ...

Ring signature was first introduced in 2001. In a ring signature, instead of revealing the actual identity of the message signer, it specifies a set of possible signers. The verifier can be convinced that the signature was indeed generated by one of the ring members, however, she is unable to tell which member actually produced the signature.

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 ...

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.

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.
