Abstract

The invention discloses an arbitration quantum signature method based on glass color sampling random unitary operation. The arbitration quantum signature method comprises an initialization stage, a signature stage and a verification stage. The initialization stage is used for preparing a secret key and establishing a communication system; the signature stage is used for selecting a proper signature algorithm to design the signature of the transmission information; and the verification stage is used for verifying the validity of the signer and the integrity and authenticity of original information. According to the invention, unitary operation encryption based on glass color sampling is adopted in the signature of transmission information designed in arbitration quantum signature; an m-modequantum state is transferred by adopting quantum walk invisible transmission based on a graph, a necessary entanglement state for invisible transmission does not need to be prepared in advance, the safety is higher by adopting a common channel and a random tuple, and a glass color sampling model and a quantum walk invisible transmission model are proved to be realized through a linear optical network; and therefore, the method disclosed by the invention is high in safety, resource-saving and easy to implement in experiment.

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...
