Threshold Group Signature Scheme with Privilege Subjects Based on ECC
2010 International Conference on Communications and Intelligence Information Security, 2010This paper analyzes and studies of a threshold group signature scheme which is based on ElGamal type. In order to overcome the shortcomings of the scheme, a new threshold group signature scheme with privilege subjects based on ECC is proposed. The new scheme is able to prevent the fraud of key distribution center effectively.

Anonymous Traceability protocol based on Group Signature for Blockchain
Future generations computer systems, 2022In blockchain technology, data are stored on decentralized nodes and public to each node in the blockchain network. Hence, the focus of privacy protection in the blockchain guarantees the anonymity of transactions such that attackers cannot attain the ...

Threshold Signatures in Dynamic Groups
Future Generation Communication and Networking (FGCN 2007), 2007In this paper we present the efficient solution for the dynamical groups with the variable threshold bound. In fact we consider the more general situation, when there is a family of dynamical groups instead of one group. We were able to handle this more general situation by joining the secret sharing idea together with the certification system device ...

A secure threshold group signature scheme
Journal of Electronics (China), 2003The threshold group signature is an important kind of signature. So far, many threshold group signature schemes have been proposed, but most of them suffer from conspiracy attack and are insecure. In this paper, a secure threshold group signature scheme is proposed.

Short Threshold Dynamic Group Signatures
2020Traditional group signatures feature a single issuer who can add users to the group of signers and a single opening authority who can reveal the identity of the group member who computed a signature. Interestingly, despite being designed for privacy-preserving applications, they require strong trust in these central authorities who constitute single ...

Democratic group signatures with threshold traceability
Journal of Shanghai Jiaotong University (Science), 2009This paper presents a concrete democratic group signature scheme which holds (t, n)-threshold traceability. In the scheme, the capability of tracing the actual signer is distributed among n group members. It gives a valid democratic group signature such that any subset with more than t members can jointly reconstruct a secret and reveal the identity of

Threshold untraceable signature for group communications
IEE Proceedings - Communications, 2004Lee et al. have proposed an untraceable (t, n) threshold signature scheme which can be extended to give the original signers the ability to prove they are the true signers. The present authors add the requirement of (k, l) threshold-shared verification to the scheme of Lee et al.
