Arbitrated Quantum Signature Method Based on Bose Sampling Random Unitary Operation

Abstract

The invention discloses an arbitration quantum signature method based on Bose sampling random unitary operation, including an initialization stage, a signature stage and a verification stage; the initialization stage is used to prepare a key and establish a communication system; the signature stage is used to select a suitable signature The algorithm designs the signature of the transmitted information; the verification phase is used to verify the validity of the signer and the integrity and authenticity of the original information. The present invention adopts the unitary operation encryption based on Bose sampling in the signature of the transmission information in the arbitration quantum signature, adopts the quantum walk teleportation based on the graph to transfer the m-mode quantum state, and the necessary entanglement state for teleportation does not need Prepared in advance, the employment of public channels and random tuples makes the security higher, and the teleportation model using the Bose sampling model and the quantum walk has been proven to be realized through a linear optical network; therefore, the method of the present invention has high security and saves resource and easy to implement experimentally.

Description

technical field [0001] The invention belongs to the field of quantum communication, and in particular relates to an arbitration quantum signature method based on Bose sampling random unitary operation. Background technique [0002] With the development of information technology, electronic certification has become one of the most important links in people's daily production and life. [0003] In a real society full of contradictions and conflicts of interests, there are many phenomena such as counterfeiting and fraud of various identities, forgery and tampering of news. In order to reduce or avoid the occurrence of these situations, a reliable authentication system needs to be established. The purpose of building an authentication system mainly includes two points: first: to verify the identity of the user to prevent counterfeiting and denial; second: to verify the authenticity of the source of the message and the integrity of the message to avoid denial, forgery, and tampe...
