Sequential Quantum Multiparty Signature Based on Quantum Fourier Transform and Chaotic System

Abstract

Motivated by the quantum Fourier transform (QFT), a sequential quantum multiparty signature (QMS) scheme is proposed. Several signatories jointly accomplish the task in a chaotic encryption system. Alice generates and sends the encrypted message with the quantum Fourier transform. Signatories provide individual signatures in a certain order, while Bob verifies the authenticity of the combined multiple signatures after the eavesdropping check phase with help of the arbitrator. Analysis shows the correctness and security of the proposed scheme. This QMS protocol increases the efficiency of verification compared to arbitrated quantum signatures and broadcasting multiparty signature. This QMS protocol will be widely used for online e-government and e-business systems.

Quantum homomorphic aggregate signature based on quantum Fourier transform

“…This scheme uses a highdimensional quantum carrier to transmit measurement information encrypted by QFT and permutation algorithms, which can not only resist general forgery attacks but also effectively prevent selective forgery attacks. In 2020, Lou et al [27] proposed an ordered quantum multi-party signature scheme based on QFT and chaotic systems. In this scheme, the message sender uses QFT encryption and sends the message.…”

Edge-assisted quantum protocol for secure multiparty logical AND its applications

“…13 Since that, quantum cryptography has attracted a lot of scientific attention from the cryptography community. Besides QKD, quantum cryptography covers a wide range of research areas, e.g., quantum secret sharing, 14 quantum perfect encryption, 15 quantum signature, 16 quantum secure direct communication, 17 quantum key agreement, 18 and so on.…”
