초록

At Eurocrypt'91, D. Chaum and E. Heyst introduced the notion of group signatures, which allow members of a group to make signatures on behalf of the group while remaining anonymous. This paper first presents a new type of group signatures with observers. In group signatures with observers, our solution is the most practical group signature scheme, under the assumption that Chaum's electronic wallet is secure.
