Query: A Digital Signature with Threshold Generation and Verification   This paper proposes a signature scheme where the signatures are generated by
the cooperation of a number of people from a given group of senders and the
signatures are verified by a certain number of people from the group of
recipients. Shamir's threshold scheme and Schnorr's signature scheme are used
to realize the proposed scheme.
