A Quantum Aggregate Signature Scheme Based on Quantum Teleportation Using Four-qubit Cluster State

With the development of quantum computing theory, classical digital signature scheme has encountered unprecedented challenges, which further facilitated the development of quantum digital signatures. In this paper, we propose a quantum aggregate signature scheme based on quantum teleportation using four-qubit cluster state. The security analysis shows that our scheme can neither be disavowed by the signers nor forged by any illegal attackers. In addition, the intercept-resend attack is invalid in our scheme.
