- Abstract
Different from traditional digital signatures, quantum blind signatures can implement a signature without knowing the specific content, and their security is guaranteed by the basic principles of quantum mechanics with unconditional security. Based on the blind signature, multi-proxy signature can avoid internal attacks efficiently by dispersing the authority of proxy signers. In this paper, we propose a new quantum multi-proxy blind signature scheme based on cluster states. We apply the quantum teleportation to transmit data using the four-particle cluster state as a channel. Then, a quantum multi-proxy blind signature scheme is designed. According to the security analysis, blindness, undeniability and unforgeability are all equipped in our scheme. Meanwhile, compared with existing schemes, four-particle cluster states are required as quantum channels in our scheme which uses fewer resources to transmit data and has higher efficiency of signatures.
