Efficient leakage-resilient blind and partially blind signatures

International Journal of Embedded Systems, 2018
The techniques of the blind and partially blind signatures play an important role in numerous applications, most prominently in electronic voting and electronic cash. In this paper, we first present formal definitions of leakage-resilient blind and partially blind signatures.

Untraceability of Partial Blind and Blind Signature Schemes

2020
Blind Signature is employed in privacy related protocols, where signer signs on a blinded message. It provides anonymity in various cryptographic applications such as electronic voting, digital cash system etc. Concerning the need for quantum resistant scheme, Ruckert and Tian et al.

Certificateless Partially Blind Signatures

2009 First International Conference on Information Science and Engineering, 2009
Partially blind signature is a variant of blind signature. It allows a signer to explicitly include common information in a blind signature under some agreement with a receiver. It provides anonymity of users in applications such as electronic voting and electronic payment systems. While certificateless public key cryptography eliminates the key escrow

An Efficient ID Based Proxy Signature, Proxy Blind Signature and Proxy Partial Blind Signature

2008 International Conference on Information Technology, 2008
Identity-based (ID based) public key cryptosystem gives an efficient alternative for key management as compared to certificate based public key settings. A proxy signature is a method for an entity to delegate signing capabilities to other participants so that they can sign on behalf of the entity with in a given context.

Cryptoanlaysis of a Self-Certified Partially Blind Signature and a Proxy Blind Signature

2009 WASE International Conference on Information Engineering, 2009
As a special digital signature, blind signature allowsallows a user to get a signature without giving the signerany information about the actual message or the resultingsignature. Unforgeability is an important property of blindsignature, it assures that any one cannot produce a forgedsignature on a message in a blind signature except thesigner ...

A novel chaotic map partially blind signature scheme based on quadratic residue problems

Journal of Discrete Mathematical Sciences and Cryptography
A Novel Partially Blind Signature Scheme (PBSS) Using Quadratic Residue (QR) and Chaotic Map (CM) Issues. To avoid the signer learning the contents of the message, the user can use a blind signature to acquire their consent. Yet, there remains situations

Fair Partially Blind Signatures

2010
It is well-known that blind signature schemes provide full anonymity for the receiving user. For many real-world applications, however, this leaves too much room for fraud. There are two generalizations of blind signature schemes that compensate this weakness: fair blind signatures and partially blind signatures.

PARTIALLY BLIND SIGNATURES BASED ON QUANTUM CRYPTOGRAPHY

International Journal of Modern Physics B, 2012
In a partially blind signature scheme, the signer explicitly includes pre-agreed common information in the blind signature, which can improve the availability and performance. We present a new partially blind signature scheme based on fundamental properties of quantum mechanics.

A Proxy Partially Blind Signature Scheme with Proxy Revocation

2010 International Conference on Broadband, Wireless Computing, Communication and Applications, 2010
The constant privilege misuse of the signers is one of the most common problems of the schemes of proxy blind signatures. In 2008, Liu et al. proposed a proxy signature scheme capable of revoking proxy privileges. In this method, the original signer can terminate the proxy privilege at any time without needing to go through a commonly trusted third ...

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.
