Efficient traceable ring signature scheme without pairings
Advances in Mathematics of Communications, 2020 Although currently several traceable (or linkable) ring signature schemes have been proposed, most of them are constructed on pairings. In this paper, we present an efficient traceable ring signature (TRS) scheme without pairings, which is based on the ...

Threshold ring signature: generic construction and logarithmic size instantiation
CybersecurityA ring signature is a variant of normal digital signature and protects the privacy of a specific signer in the sense that a ring signature can be verified, but the signer’s identity can only be traced to a limited set. The concept was further enhanced to

Selectively Linkable and Convertible Ring Signature Scheme Based on DLP [PDF]
Jisuanji gongcheng, 2019 Most of the existing linkable and convertible ring signature schemes do not have strong anonymity.To solve this problem,a ring signature scheme based on Discrete Logarithm Problem(DLP) is proposed.The actual signer establishes an association tag by ...

Designated verifier ring signature and ring signcryption
International Journal of Intelligent Information and Database Systems, 2013 Ring signatures can achieve the anonymity of the users who want to sign documents not only in the authenticated way but also in the confidential way. Based on the k-CAA2 assumption, a security designated verifier ring signature scheme is proposed from bilinear pairing.

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 ...

A New Constant-Size Group Signature Scheme From Lattices
IEEE Access, 2020 A lattice-based group signature scheme (LGSS) is an active cryptographic primitive, where each group member can sign messages anonymously in the name of the entire group and each valid signature should be traced to some group member on the lattice.

Practical periodic deniable signature scheme based on ISRSAC
Journal of King Saud University: Computer and Information SciencesIn periodic deniable ring signature schemes, ring members have the ability to periodically confirm or deny their role as signers according to a protocol, without the need for third-party intervention—this is referred to as periodic deniable ring ...
