Post-Quantum Secure Identity-Based Proxy Blind Signature Scheme on a Lattice [PDF]
Entropy, 2023 Blind signatures have been widely applied when privacy preserving is required, and the delegation of blind signature rights and a proxy blind signature (Proxy-BS) become necessary when the signer cannot sign.

A New Quantum Blind Signature Scheme with BB84-State [PDF]
Entropy, 2019 The blind signature is widely used in cryptography applications because it can prevent the signer from gaining the original message. Owing to the unconditional security, the quantum blind signature is more advantageous than the classical one.

Cryptanalysis of Lattice-Based Blind Signature and Blind Ring Signature Schemes [PDF]
IEEE Access, 2021 A blind signature enables a user to obtain signatures on any message from an authority who cannot acquire any information on the message being signed. A blind ring signature scheme is designed as a ring signature scheme with the blindness property.

Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation [PDF]
Entropy, 2022 We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel.

Lattice-based Blind Signatures [PDF]
, 2009 Motivated by the need to have secure blind signatures even in the presence of quantum computers, we present two efficient blind signature schemes based on hard worst-case lattice problems.

Blind Collective Signature Protocol [PDF]
Computer Science Journal of Moldova, 2011 Using the digital signature (DS) scheme specified by Belarusian DS standard there are designed the collective and blind collective DS protocols. Signature formation is performed simultaneously by all of the assigned signers, therefore the proposed ...

Two-Party Cooperative Blind Signature Scheme Based on SM9 [PDF]
Jisuanji gongcheng, 2023 In the existing SM9 blind signature scheme，the signature private key is leaked easily and the signature power is centralized，which are problematic.Hence，a two-party collaborative blind signature scheme based on SM9 is proposed.The Key Generation Center ...

Partial blind signature scheme based on SM9 algorithm
网络与信息安全学报, 2021 Ordinary digital signatures have many deficiencies in effectively protecting users' privacy, and signature repudiation and tracking occur from time to time. In order to solve the above problems, a partial blind signature scheme based on the SM9 algorithm

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 ...

Attribute-Based Blind Signature Scheme Based on Elliptic Curve Cryptography
IEEE Access, 2022 Blind signature is a special digital signature that allows the signer to sign a document without knowing its content. However, in many situations, multiple people need to blindly sign messages.
