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 ...

On Design of Single-Layer and Multilayer Code-Based Linkable Ring Signatures
IEEE Access, 2020 In this paper, we present an effective code-based linkable ring signature scheme based on Borromean ring signature. The security of the scheme is based on the hardness of Syndrome Decoding problem, General Syndrome Decoding problem and Codeword Finding ...

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 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,

A New Code‐Based Linkable Threshold Ring Signature Scheme
Wireless Communications and Mobile Computing, 2022 In this paper, we construct a new code‐based linkable threshold signature scheme whose security is based on the hardness of the syndrome decoding problem and general syndrome decoding problem. We show that our scheme is secure in terms of existential unforgeability, anonymity, nonslanderability, and linkability.

Cloud data anonymous assured deletion approach based on blockchain
Dianxin kexue, 2021 The previous assured deletion schemes ignored that the privacy is threated by the relevance between data and user identity, exposing user behavior to the cloud service provider or attackers.Aiming at the above problems, an assured deletion approach based

Privacy-Protected Deletable Blockchain
IEEE Access, 2020 A deletable blockchain has been proposed recently to change the immutability of the traditional blockchain. However, the users' identities and transaction contents are all public in the scheme, and the public data may reveal the users' privacy.
