Threshold proxy signatures

IEE Proceedings - Computers and Digital Techniques, 1999
A (t, n) threshold proxy signature scheme allows t or more proxy signers from a designated group of n proxy signers to sign messages on behalf of an original signer. The authors review both Zhang's threshold proxy signature scheme and Kim's threshold proxy signature scheme.

Confessible Threshold Ring Signatures

2006 International Conference on Systems and Networks Communications (ICSNC'06), 2006
We present two threshold ring signature schemes with different properties. One focuses on the confessibility (or signer verifiability) and the denouncibility properties. The other focuses on the threshold-confessibility. Our schemes are built on generic ring signature schemes and can be easily adapted to most existing ring signature schemes.

Identity Based Threshold Ring Signature

2005
In threshold ring signature schemes, any group of t entities spontaneously conscript arbitrarily n – t entities to generate a publicly verifiable t-out-of-n signature on behalf of the whole group, yet the actual signers remain anonymous. The spontaneity of these schemes is desirable for ad-hoc groups such as mobile ad-hoc networks.

Quantum threshold group signature

Science in China Series G: Physics, Mechanics and Astronomy, 2008
In most situations, the signer is generally a single person. However, when the message is written on behalf of an organization, a valid message may require the approval or consent of several persons. Threshold signature is a solution to this problem.

Threshold Discernible Ring Signatures

2012
A ring signature [1] demonstrates that the signer who produced it is among a group A of n people, called a ring. A signer may produce a ring signature on any ring A he is part of, arbitrarily without any setup procedure or the consent of anyone in A. Several extensions of ring signatures have been proposed in literature.

Certificateless Threshold Signature Schemes

2005
We analyze the relationship and subtle difference between the notion of certificateless public key cryptography (CL-PKC) and identity-based schemes without a trusted private key generator (PKG), then propose a certificateless threshold signature scheme based on bilinear pairings.

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.

Threshold Entrusted Undeniable Signature

2005
Entrusted undeniable signatures are like undeniable signatures, except that the disavowal protocol can only be run by a court in order to resolve a formal dispute. This paper introduces threshold entrusted undeniable signature scheme without trusted center.
