Blind Signature System

1984
A cryptographic system allows, in one exemplary use, a supplier (101) to cryptographically transform a plurality of messages responsive to secret keys; the transformed messages to be digitally signed by a signer (102); and the signed transformed messages returned to the supplier (101) to be transformed by the supplier (101), responsive to the same ...

Fair quantum blind signatures

Chinese Physics B, 2010
We present a new fair blind signature scheme based on the fundamental properties of quantum mechanics. In addition, we analyse the security of this scheme, and show that it is not possible to forge valid blind signatures. Moreover, comparisons between this scheme and public key blind signature schemes are also discussed.

Efficient Identity-Based Signatures and Blind Signatures

2005
In this paper, we first propose an efficient provably secure identity-based signature (IBS) scheme based on bilinear pairings, then propose an efficient identity-based blind signature (IBBS) scheme based on our IBS scheme. Assuming the intractability of the Computational Diffie-Hellman Problem, our IBS scheme is unforgeable under adaptive chosen ...

Fair Blind Signatures Revisited

2007
This paper presents a formal model for fair blind signature schemes and a provably secure scheme based on bilinear maps. A blind signature scheme is a protocol for obtaining a signature on a message which is unknown from the signer. Furthermore, the signer cannot link his transcript of a protocol to the resulting message-signature pair.

Rerandomizable Threshold Blind Signatures

2015
This paper formalizes the concept of threshold blind signatures TBS that bridges together properties of the two well-known signature flavors, blind signatures and threshold signatures. Using TBS users can obtain signatures through interaction with t-out-of-n signers without disclosing the corresponding message to any of them.

Unconditionally Secure Blind Signatures

2009
The blind signature scheme introduced by Chaum allows a user to obtain a valid signature for a message from a signer such that the message is kept secret for the signer. Blind signature schemes have mainly been studied from a viewpoint of computational security so far. In this paper, we study blind signatures in unconditional setting.

Improved low-computation partially blind signatures

Applied Mathematics and Computation, 2003
Blind signatures were introduced in 1983 as a building block for an untraceable electronic cash system. Later on, the partial blindness property was proposed in order to deal with some practical problems in an electronic cash system. In the paper known partially blind signature schemes are first briefly reviewed.
