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 ...

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.

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.

Skipping the q in Group Signatures
2020The notion of group signatures was introduced to allow group members to sign anonymously on behalf of a group. A group manager allows a user to join a group, and another will be able to open a signature to revoke its anonymity. Several schemes have already been proposed to fulfil these properties, however very few of them are proven in the standard ...

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.

Improving Revocation for Group Signature with Redactable Signature
2021Group signature is a major cryptographic tool allowing anonymous access to a service. However, in practice, access to a service is usually granted for some periods of time, which implies that the signing rights must be deactivated the rest of the time. This requirement thus calls for complex forms of revocation, reminiscent of the concept of time-bound
