Efficient Quantum Blind Signature Scheme Based on Quantum Fourier Transform

Different from traditional signature schemes, the paper gives a novel protocol which uses quantum logic gates to perform operations on quantum states, and it realizes the quantum state representation of two classical information and uses mixed entangled states to measure information. The binary measurement results of the protocol are converted into blocks of a certain length, and these blocks are encrypted by quantum Fourier transform and transmitted through N-dimensional quantum states. In the proposed protocol, the quantum channel uses N-dimensional quantum states, which is more efficient than the currently proposed two-dimensional information carrier channel protocol. The security analysis of this article shows that the program is anti-counterfeit, undeniable and blind. In addition, compared with other existing efficiency analysis schemes, this scheme has higher signature efficiency.
