Cutting the GRASS: Threshold GRoup Action Signature Schemes

open access: yesIACR Cryptology ePrint Archive, 2023
Group actions are fundamental mathematical tools, with a long history of use in cryptography. Indeed, the action of finite groups at the basis of the discrete logarithm problem is behind a very large portion of modern cryptographic systems. With the advent of post-quantum cryptography, however, other group actions, such as isogeny-based ones, received ...

An Elliptic Curve Threshold Group Signature Scheme [PDF]

open access: yesInternational Conference on Aerospace Sciences and Aviation Technology, 2013
In a (t,n) threshold group signature scheme, only t or more signers of the group can sign messages on behalf of the group. Elliptic Curve Cryptography (ECC) was introduced by Victor Miller and Neal Koblitz in 1985. ECC proposed as an alternative to established public-key systems such as DSA and RSA.

Efficiency identity-based threshold group signature scheme

open access: yesTongxin xuebao, 2009
Threshold group signature was used to guarantee the security of the collective decision.To improve the efficiency,a new identity-based cryptography threshold group signature scheme was proposed basing on bilinear pairing and secret sharing.In this scheme,

"Discrete Logarithm based 't, n' Threshold Group Signature Scheme"

open access: yesInternational Journal of Computer Applications, 2011
of the Internet has boosted electronic information exchange on both the personal and business levels. There is a need of the authentication of messages sent by a group of individuals to another group. A (t, n) threshold group signature scheme is a method for allowing a member of a group to anonymously sign a message on behalf of the group.

Research Progress and Prospect of Ring Signatures [PDF]

open access: yesJisuanji kexue yu tansuo, 2023
As a special group signature, ring signature has been widely used in anonymous voting, anonymous deposit and anonymous transaction because it can not only complete the signature without the cooperation of ring members, but also ensure the anonymity of ...
