Title: Research on Group Signature Based on Vector Space Secret Sharing
Abstract: Vector space secret sharing group signature is a generalization of group signature. In this paradigm, only members from an authorized subset can represent the group to generate a signature. The signature is anonymous and the identities of the participating signers can be revealed in case of a dispute. Firstly, we analyze the security of a group signature presented by Ma Chunbo et al. and point out that it is forgeable, linkable and framing. Based on vector space secret sharing and bilinear pairing, a new group signature is proposed, which solve the problems in Ma's scheme and is very simple and efficient. Therefore, it is a practical group signature scheme.
