| Abstract: | Unconditionally secure signature is an important part of quantum cryptography. Usually, a signature scheme only provides an environment for asingle signer. Nevertheless, in real applications, many signers maycollaboratively send a message to the verifier and convince the verifierthat the message is actually transmitted by them. In this paper, we give ascalable arbitrated signature protocol of classical messages with multi-signers. Its security is analyzed and proved to be secure even with a compromised arbitrator. |
