Description
Summary:With the development of information society, network security problems are becoming more and more serious, and digital signature as an authentication method is widely used in many fields such as information security and e-commerce, mainly to solve security problems such as forgery, repudiation, impersonation and tampering [1]. The latest quantum technology can overcome a series of difficult problems of classical digital signatures in a very short time. In this paper, we propose a quantum multiproxy blind signature scheme, in which the original signer is unable to sign the document himself, and delegates multiple proxy signers to sign and verify the document, and the signature order of the proxy signers is not restricted. The scheme adopts techniques such as Unitary transformation and Hadamard gate, and uses quantum key distribution protocol to ensure its security, which improves the efficiency of signature, ensures the security of signature, and has certain anti-attack capability.
