Hierarchical Group Signatures

2005
We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the signers as leaves. When opening a signature a group manager only learns to which of its subtrees, if any, the signer belongs.

Step-out group signatures

Computing, 2009
The authors design a new kind of signature which is the title of the paper. In this scheme the signer is the only person who may prove that they were not the signer. This reverses the usual situation. Their scheme allows more convenient personal data protection rules, given that the signer is not revealed, so their is no requirement to protect this ...

Certificateless group inside signature

Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005., 2005
In distributed networks, the signer wants his signature to be verified by anyone in the same group with him and the recipient wants to verify the signature independently. Motivated by this consideration, a certificateless group inside signature is presented in this paper.

Generalized group signature scheme

Wuhan University Journal of Natural Sciences, 2001
The concept of generalized group signature scheme will be present. Based on the generalized secret sharing scheme proposed by Lin and Harn, a non-interactive approach is designed for realizing such generalized group signature scheme. Using the new scheme, the authorized subsets of the group in which the group member can cooperate to produce the valid ...

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.

Study of the amidase signature group

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1996
Computer methods for database search, multiple alignment and cluster analysis indicated significant homology between amino-acid sequences of 21 amidases or amidohydrolases (EC 3.5). All of them were found to be involved in the reduction of organic nitrogen compounds and ammonia production.

Group Signature Formulas Constructed from Graphs

Algebra and Logic, 2022
Let \(\Gamma=(X,E)\) be a finite undirected graph without loops and let \(\mathfrak{M}\) be a variety of groups. The author defines the partially commutative group \(F(\Gamma; \mathfrak{M})\) in \(\mathfrak{M}\) as \[ F(\Gamma; \mathfrak{M})=\big \langle X \; \big | \; x_{i}x_{j}=x_{j}x_{i} \text{ if } \{x_{i},x_{j}\} \in E \big \rangle \in \mathfrak{M}

Group theoretic signature analysis

IEEE Transactions on Computers, 1990
A new class of data-compression techniques called group-theoretic signature analysis (GTSA) for testing a logic network is proposed, and the fault coverage of the method is analyzed. This method is a generalization of accumulator compression testing. Built-in-self-test for processor environments is feasible with GTSA. >

Verifiably Encrypted Group Signatures

2017
Recently, verifiably encrypted signatures (VESs) have been widely used in fair exchange, however most of them do not provide a method to protect the anonymity of the signer, leading to privacy leakage in fair exchange. Verifiably Encrypted Group Signature (VEGS) overcomes drawbacks of VES, which allows a verifier to check its validity without ...

Adaptable Designated Group Signature

2006
An adaptable designated group signature is presented in this paper. In contrast with traditional group oriented signature, the new one laid a strong emphasis on how to improve the signer’s efficiency. In fact, this new type of designated group signature can be seen as a type of designated verifier signature.
