Efficient Blind and Partially Blind Signatures Without Random Oracles [chapter]

Tatsuaki Okamoto
2006 Lecture Notes in Computer Science  
This paper proposes a new ecient signature scheme from bilinear maps that is secure in the standard model (i.e., without the random oracle model).  ...  Here, partially blind signatures are a generalization of blind signatures (i.e., blind signatures are a special case of partially blind signatures) and have many applications including electronic cash  ...  We assume that A forges the blind signature scheme with non-negligible (in n) probability and breaks the binding condition of commit with negligible (in n) probability .  ...

2019 JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES  
A partially blind signature enables a signer to explicitly incorporate a pre-agreed common information into a blind signature without the loss of blindness property.  ...  In order to improve the efficiency, in this paper, we propose a new pairing free partially blind signature scheme with message recovery in the identity-based frame work.  ...  The partially blind signature schemes, thus play a crucial role in designing an efficient and secure e-cash payment.  ...

A Short Paper on Blind Signatures from Knowledge Assumptions [chapter]

Lucjan Hanzlik, Kamil Kluczniak
2017 Lecture Notes in Computer Science  
There are known efficient blind signature schemes based on the random oracle model and on the common reference string model.  ...  We present a blind signature scheme that is two-move, setup-free and comparable in terms of efficiency with the results of Fuchsbauer et al. Its security is based on a knowledge assumption.  ...  Miros law Kuty lowski and the FC's anonymous reviewers for their valuable comments on this short paper.  ...

Two Improved Partially Blind Signature Schemes from Bilinear Pairings [chapter]

Sherman S. M. Chow, Lucas C. K. Hui, S. M. Yiu, K. P. Chow
2005 Lecture Notes in Computer Science  
In this paper, we propose a threshold partially blind signature scheme from bilinear pairings and an ID-based partially blind signature scheme, which are provably secure in the random oracle model.  ...  Partially blind signature is a variant such that part of the message contains pre-agreed information (agreed by the signer and the signature requester) in unblinded form, while threshold blind signature  ...  Fangguo Zhang for pointing out the mistake of the preliminary version of this paper (by showing a changing agreed information attack on the scheme) and all the anonymous reviewers for their helpful comments  ...

Fair Partially Blind Signatures [chapter]

Markus Rückert, Dominique Schröder
2010 Lecture Notes in Computer Science  
There are two generalizations of blind signature schemes that compensate this weakness: fair blind signatures and partially blind signatures.  ...  In partially blind signature schemes, the signer retains a certain control over the signed message because signer and user have to agree on a specific part of the signed message.  ...  They are indebted to one particular reviewer who provided exceptionally detailed comments and helped in improving the presentation as well as eliminating inconsistencies.  ...
