Threshold untraceable signature for group communications

open access: yesIEE Proceedings - Communications, 2004
Lee 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.

Threshold Ring Signature Scheme from Cryptographic Group Action

open access: yes, 2023
A threshold ring signature (t-out-of-N) is an extension of ring signatures that allow t users jointly sign a message on the behalf of N users, selected in an arbitrary manner, while keeping their identities anonymous. This paper presents a construction of threshold ring signature from cryptographic group action, based on the OR proof of group action ...

A Threshold Group Signature Authentication Scheme for VANETs

The 2nd International Conference on Computing and Data Science, 2021
Vehicular Ad Hoc Networks (VANETs) have recently received significant attention in improving traffic safety and privacy protection. In this paper, we proposed a novel efficient message authentication scheme based on the threshold group signature. We use elliptic curve ciphers to construct a lightweight security authentication scheme, reducing the ...
