Cryptoanalysis of Certificateless Partially Blind Signature and Proxy Blind Signature Scheme

2009 2nd International Congress on Image and Signal Processing, 2009
Blind signature and proxy signature are two im- portant crytographical primitives. Unforgeability is a primitive property of digital signature, it assures that any one cannot produce a forged signature on a message except the signer. However, blindness is an important property which distinguish with other signatures.

A Certificateless Restrictive Partially Blind Signature Scheme

2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2008
Restrictive partially blind signatures incorporate the idea of partially blind signatures and restrictive blind signatures, which have the property of partial blindness and restrictive blindness. The existing restrictive partially blind signature schemes were constructed under certificate-based public key cryptosystems or identity-based public key ...

Cryptanalysis of Huang–Chang partially blind signature scheme

Journal of Systems and Software, 2005
Partially blind signature is an extension of blind signature that allows a signer to sign a partially blinded message that include pre-agreed information such as expiry date or collateral conditions in the resulting signatures. It is more useful than blind signature in many applications, such as electronic cash (e-cash) system.

A new design of efficient partially blind signature scheme

Journal of Systems and Software, 2004
Recently, the techniques of the partially blind signatures played an important role in many electronic commerce applications. Therefore, to guarantee the quality of the growing popular communication services, it is urgent to construct low-computation partially blind signature scheme for both parties of the signer and the requester to obtain a signature.

A simpler restrictive partially blind signature

2006 First International Symposium on Pervasive Computing and Applications, 2006
A blind signature scheme is a protocol for obtaining a digital signature from a signer, but the signer can neither learn the messages he/she sign nor the signatures the signature requesters obtain afterwards. A partially blind signature scheme is a variant such that part of the message contains pre-agreed information (agreed by the signer and the ...

Untraceable partially blind signature based on DLOG problem

Journal of Zhejiang University: Science A, 2004
This paper proposes a new untraceable Partially Blind Signature scheme which is a cross between the traditional signature scheme and the blind signature scheme. In this proposed scheme, the message M that the signer signed can be divided into two parts.

A quantum partially blind signature scheme without entanglement

International Journal of Modern Physics B, 2022
In a quantum partially blind signature (QPBS) scheme, the contradiction between anonymity and controllability of completely blind signature (BS) schemes was better solved by adding common negotiated public information between the signer and the requester

Convertible Undeniable Partially Blind Signatures

19th International Conference on Advanced Information Networking and Applications (AINA'05) Volume 1 (AINA papers), 2005
This paper extends the concept of partially blind signature to the convertible undeniable partially blind signature, in which only the signer can verify and confirm the validity of given signatures and convert given signatures into universally verifiable signatures, along with a formal definition for it and a practical scheme that implements it.

Provably Secure Pairing-Free Identity-Based Restrictive Partially Blind Signature Scheme

2019 IEEE 3rd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2019
The restrictive partially blind signature (RPBS) scheme permits user to explicitly incorporate the common information consulted with signer into the signature, but the choice of message is restricted to certain rules. Many RPBS schemes have been designed

Partially Blind ECDSA Scheme and Its Application to Bitcoin

International Conference on Data Science in Cyberspace, 2021
Blind signatures allow a user to obtain a signature without revealing message information to the signer. However, in many cases, the signer must record additional information relevant to the signature.
