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 ...

Identity-Based Partially Blind Signature Scheme: Cryptanalysis and Construction
IEEE Access, 2021 Blind signature is a special type of digital signature, the signer cannot see the specific content signed. However, blindness may cause users to abuse their rights.

, 1995 A blind signature scheme is a protocol for obtaining a signature from a signer such that the signer's view of the protocol cannot be linked to the resulting message-signature pair. Blind signature schemes are used in anonymous digital payment systems.

On blindness of several ElGamal-type blind signatures
Prikladnaya Diskretnaya Matematika, 2023 Blind signature schemes are the essential element of many e-cash and e-voting systems. Anonymity in such systems is ensured through the blindness property of the signature schemes. We discuss the blindness property and analyze several ElGamal-type blind signature schemes regarding this property. We present effective attacks violating blindness on three

A Blind Adaptive Decorrelating Detector Using Spatial Signature Estimation [PDF]
, 2006 The decorrelating detector is one of the detecting methods in a direct sequence code division multiple access systems. We investigate the blind adaptive decorrelating detector (BADD) using only the signature of the desired user (DU) according to the ...

Improved Self-certified Partially Blind Signature Scheme [PDF]
, 2020 Blind signature allows one user to get a signature without giving the signer any information about the actual message or the resulting signature. In this paper, we aim to improve the recently proposed Lin et al.’s Self-certified Partially Blind Signature
