A group signature scheme introduced by Chaum and Van Heyst allow a group member to sign message anonymously on behalf of the group. However, in the case of a dispute, the identity of a signer can be revealed by a group maneger. A group signature schemes have mainly been studied from a viewpoint of computational security setting so far. In this paper, we study group signatures with the viewpoint of unconditionally secure setting. Especially, we newly introduce a model and security notions of unconditionally secure group signatures(USGS, for short). And, we formulate our security notions. Furthermore, we propose a construction method for USGS that are provably secure in our strong security notions. |
