Weblinkable ring signature scheme, the signer remains anonymous in the group, but two signatures generated by the same signer can be linked. The property, linkability, allows … WebKeywords: ring signatures, designated verifier, non-transferability, link-ability, anonymity 1 Introduction We present Designated-Verifier Linkable Ring Signatures (DVLRS), a new type of privacy-oriented digital signature. Our primitive is a linkable ring signature [15], i.e. it protects the anonymity of the signers by ‘hiding’ their ...

Web4 de jun. de 2024 · We present a linkable ring signature construction with concise signatures and multi-dimensional keys that is linkably anonymous if a variation of the decisional Diffie-Hellman problem with random oracles is hard, linkable if key aggregation is a one-way function, and non-slanderable if a one-more variation of the discrete logarithm ... WebThis paper constructs an identity-based linkable ring signature (LRS) scheme over NTRU lattice by employing the technologies of trapdoor generation and rejection sampling. The security of this scheme relies on the small integer solution (SIS) problem on NTRU lattice.

We introduce Designated-Verifier Linkable Ring Signatures (DVLRS), a novel cryptographic primitive which combines designated-verifier and linkable ring … Web14 de set. de 2024 · 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. We propose a comprehensive security model, and construct a scheme …
Web17 de set. de 2024 · In this paper, we point out the difficulties of creating tightly-secure ring signatures (RS) and linkable ring signatures (LRS), then present solutions to overcome them. As a result, we construct a tightly-secure RS scheme that is more efficient than the … WebTight security is increasingly gaining importance in real-world cryptography, as it allows to deploy the cryptosystem without compensating the security loss of a reduction with …
Web16 de mar. de 2024 · A linkable ring signature extends this concept by including a "key image". When you create the ring and use a particular private key to "join the ring", a key image is declared which is a public key corresponding to that private key, except on a different generator point. Because of the EC discrete-log problem, no one can tell which …
