Abstract :
There is a signature scheme which can aggregate two or more persons´ signatures to one, called an aggregate signature. In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier. By this functionality, no one other than the designated-verifier can verify the signature, so the signature passed to other persons would not appear where the signer does not intend to send it in the form which anyone can verify
