Efficient Partially Blind Signatures with Provable Security
2006Blind signatures play a central role in applications such as e-cash and e-voting systems. The notion of partially blind signature is a more applicable variant such that the part of the message contains some common information pre-agreed by the signer and the signature requester in an unblinded form.

RSA-based partially blind signature with low computation
Proceedings. Eighth International Conference on Parallel and Distributed Systems. ICPADS 2001, 2002With a partially blind signature scheme, the signer inoculates non-removable common information into his blind signature. This common information may represent the date or the amount of cash. Due to its untraceability and partial blindness property, the partially blind signature plays an important role in many e-commerce applications.

Provably secure robust threshold partial blind signature
Science in China Series F: Information Sciences, 2006Threshold digital signature and blind signature are playing important roles in cryptography as well as in practical applications such as e-cash and e-voting systems. Over the past few years, many cryptographic researchers have made considerable headway in this field.

Attack on Undeniable Partially Blind Signatures
2007Blind signatures allow a user to get a signature on any message without revealing the content of the message to the signer. Partially blind signatures allow the signer to explicitly include common information in the blind signature under some agreement with the user. Undeniable signatures can only be verified with the help of the signer.

An enhanced RSA-based partially blind signature
2010 International Conference on Computer and Communication Technologies in Agriculture Engineering, 2010Hwang et al. showed that the Chien et al.'s partially blind signature scheme based on RSA public cryptosystem could not meet the untraceability property of a blind signature. In this paper, we proposed an enhanced version of Chien et al.'s partially blind signature scheme based on RSA.

Convertible Undeniable Partially Blind Signature from Bilinear Pairings
2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing, 2008Undeniable signature is a kind of signatures that the validity or invalidity of a signature can only be verified with the help of the signer. On the other hand, the concept of blind signature is to enable a user to obtain a signature on a message which is unknown to the signer.

Secure joint Bitcoin trading with partially blind fuzzy signatures
Soft Computing, 2015Bitcoin has recently received considerable attentions in both academia and industrial areas. It is an appealing anonymous electronic cash system-based peer-to-peer computer networks and does not rely on any centralized trusted authority. The Bitcoin is associated with a public/secret key pair where the security key is only known by its Bitcoin account ...

Efficient Partially Blind Signature Scheme with Provable Security
2006Partially blind signature was first introduced by Abe and Fujisaki. Subsequently, Abe and Okamoto proposed a provably secure construction for partially blind signature schemes with a formalized definition in their work. In this paper, based on discrete logarithm problem and the Schnorr’s blind signature scheme, we propose a new efficient partially ...
