On tightly-secure linkable ring signatures
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 … 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 larger …

This repository implements a proof of concept using Ethereum and python scripts that mimic behavior of the actors involved in a voting session. ethereum blockchain evoting linkable-ring-signature. Updated on Mar 2, 2024. Weblinkable ring signatures of size log(‘)poly( ) without setup and in the standard model. Along the way, we introduce new techniques that enable us to use NIWI proofs instead of NIZK proofs, which may be of independent interest. As an additional contribution, we propose a stronger security model for link-able ring signatures and prove that our ...
Websignature. The linkable ring signature is ˙= f˙ R;opk ˇ;sigg. The verification is similar to the non-linkable version, with an additional step to verify the one-time signature. Similar to [8], we also instantiate this generic linkable ring signature with NTRU lattice using a NTRU-based Type-H signature scheme: FALCON [9]. Our analysis shows ... Web21 de out. de 2024 · Thus our linkable ring signature scheme satisfies link correctness. 4.2. Security analysis. In this subsection, we will show that our linkable ring signature is secure. Note that, in , they use the forking lemma [39, 40] (which is essentially rewinding) to prove the security of their schemes.
