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.

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 ...

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.

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.

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.

A code-based blind signature [PDF]
2017 IEEE International Symposium on Information Theory (ISIT), 2017 In this paper we give the first blind signature protocol for code-based cryptography. Our approach is different from the classical original RSA based blind signature scheme, it is done in the spirit of the Fischlin approach [9] which is based on proofs of knowledge.

Cryptanalysis of ID based Proxy-Blind signature scheme over lattice
ICT Express, 2020 In this article we review the ID Based Proxy-Blind signature scheme proposed by Zhang et al. and we give an attack on the scheme revealing the master secret key used in the construction of their scheme.

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 ...
