On a Threshold Group Signature Scheme and a Fair Blind Signature Scheme. [PDF]

IACR Cryptol. ePrint Arch., 2004
In the paper, we analyze two signature schemes. The first is a $(t_j, t, n) $ threshold group signature scheme proposed by Shi and Feng in [1]. The second is a fair blind signature scheme proposed by Feng in [2]. Our results show that both schemes are

Improved Threshold Ring Signature for Ad-Hoc Group

2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006
A number of peer to peer (P2P) systems as well as mobile ad-hoc networks (MANETs) fall into the category of ad hoc groups. Their needs for security have been widely recognized, so some signature schemes had been introduced for the ad hoc group. On the basis of analyzing those schemes, we propose a threshold ring signature from bilinear pairings for ad ...

A New ID-Based Threshold Group Signature Scheme

2012 8th International Conference on Wireless Communications, Networking and Mobile Computing, 2012
A (t,n) threshold group signature scheme allows a singer to determine a (t,n) threshold strategy and only t or more signers of the group can sign messages on behalf of the group. In this paper, we proposed a new ID-based threshold group signature scheme based on discrete logarithm problem, which not only satisfies all the secure requirements but also ...

An ID-based (k, t, n) Threshold Group Signature Scheme

2011 Seventh International Conference on Computational Intelligence and Security, 2011
The threshold signature as an important branch of digital signature has grown to become one of the most popular and prolific field of study. This paper introduced an identity-based (k, t, n) threshold group signature scheme that uses bilinear pairings and secret sharing.

A Voting Scheme in Blockchain Based on Threshold Group Signature

2019
Traditional voting schemes are used for the credit evaluation and authentication. During the voting process, the contents need to be verified through the signature algorithms. Traditional signature schemes for voting scenes exist several drawbacks such as distrust of central nodes for the group signature and inefficiency for the ring signature.

On the Security of the Li-Hwang-Lee-Tsai Threshold Group Signature Scheme

2003
A (t, n) threshold group signature scheme is a generalization of group signature, in which only t or more members from a given group with n members can represent the group to generate signatures anonymously and the identities of signers of a signature can be revealed in case of dispute later.
