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 ...

Secure E-Voting Protocol Based on SM9 Blind Signature and Ring Signature [PDF]
Jisuanji gongcheng, 2023 To solve the problems of anonymity，public verifiability，ballot collision，and forgery in the process of e-voting，an anonymous public verifiable e-voting system protocol design scheme is proposed based on SM9 algorithm.This scheme constructs an identity ...

Using Ring Learning with Errors Problem to Construct Linkable Ring Signature Scheme
Jisuanji kexue yu tansuo, 2020 In order to solve the problem of large key size and low efficiency in the linkable ring signature scheme on lattice, this paper reconstructs the linkable ring signature scheme from lattice based on the ring learning with errors (RLWE) problem, according ...

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 ...

Efficient Linkable and/or Threshold Ring Signature without Random Oracles
, 2013 Linkable ring signatures have found many attractive applications. One of the recent important extensions is a linkable threshold ring signature (LTRS) scheme. Unfortunately, the existing LTRS schemes are only secure in the random oracle model (ROM).

Efficient Linkable Ring Signature Scheme [PDF]
Jisuanji gongchengA linkable ring signature, which is a special type of ring signature, can aid in verifying whether two signatures have been signed by the same user, without compromising anonymity. This feature enables it to play an important role in blockchains. However,

Identity-based Linkable Ring Signcryption on NTRU Lattice [PDF]
Jisuanji kexueAlthough the current lattice-based ring signcryption scheme resists quantum attacks,it has large key storage and high encryption/decryption time.The linkable lattice ring signcryption scheme not only can protect signer anonymity,but also can determine ...
