Traceable Identity-Based Group Signature
RAIRO - Theoretical Informatics and Applications, 2016Summary: Group signature is a useful cryptographic primitive, which makes every group member sign messages on behalf of a group they belong to. Namely group signature allows that group member anonymously signs any message without revealing his/her specific identity.

Research on anonymous signatures and group signatures
Computer Communications, 2008In this paper, we analyze the conventional group signature schemes, and propose the notion of conflict of authenticated contents which implies the unconquerable drawbacks of the current group signature schemes and threshold signature schemes. We discuss an important problem of group signature, that is, whether the group signature is produced on behalf ...

Braid groups based group signature scheme
2015 4th International Conference on Reliability, Infocom Technologies and Optimization (ICRITO) (Trends and Future Directions), 2015In group signature schemes, the members of a group can sign on a document on behalf of the group in such a way that the identity of the signer is not known to the verifier. But in case of dispute the identity of a particular member of the group can be identified. In this paper, we propose a braid groups based group signature scheme that imitates a real

Broadcast Group Oriented Signature
2005 5th International Conference on Information Communications & Signal Processing, 2006When some one wants to sign a message for a designated group in distributed networks, he can sign the message one by one for each member in designated group, but the efficiency is very low. In this paper, we propose a new type of signature, broadcast group oriented signature, to make the signer easier.

Group signatures, introduced by Chaum and van Heyst at Eurocrypt'91, allow individual members of a group to sign messages on behalf of the group while remaining anonymous. Furthermore, in case of disputes later a trusted authority, who is given some auxiliary information, can identify the signer.

Unconditionally Secure Group Signatures
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009A group signature scheme introduced by Chaum and Van Heyst allows a group member to sign messages anonymously on behalf of the group. However, in the case of a dispute, the identity of a signer of a group signature can be revealed only by a privileged entity, called a group manager.

We construct a short group signature scheme. Signatures in our scheme are approximately the size of a standard RSA signature with the same security. Security of our group signature is based on the Strong Diffie-Hellman assumption and a new assumption in bilinear groups called the Decision Linear assumption.

In many applications of group signatures, not only a signer's identity but also which group the signer belongs to is sensitive information regarding signer privacy. In this paper, we study these applications and combine a group signature with a ring signature to create a ring group signature, which specifies a set of possible groups without revealing ...
