Quantum identity authentication method, computer, computer program and readable storage medium

Abstract

The invention belongs to the technical field of quantum communications, and discloses a quantum identity authentication method, a computer, a computer program and a readable storage medium. The methodcomprises the steps that binary identity strings of both sides are used for preparing two groups of particle sequences according to specified rules; Alice sends a first particle used for preparing aBell-state particle sequence to Bob, and Bob sends a second particle used for preparing the Bell-state particle sequence to Alice; Bell-based measurement is conducted on particles in the two sides, and the measurement results are subjected to binary representation. In the identity authentication process, no unitary transformation is needed in the Bell-state transmission process, and information transmission can be achieved simply by executing Bell-state measurement and a bitwise exclusive OR operation. In practical application, achievement of the protocol is achieved by only depending on Bell-state accurate preparation and Bell-state reliable measurement, and the protocol can resist impersonation attack.

Description

technical field [0001] The invention belongs to the technical field of quantum communication, and in particular relates to a quantum identity authentication method, a computer, a computer program, and a readable storage medium. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Since Bennett and Brassard proposed the quantum key distribution (QKD) protocol (referred to as "BB84 protocol") to open up quantum cryptography, in order to adapt to various uses and solve emerging information security problems, a large number of quantum cryptography protocols have been proposed, mainly Including: Quantum Secret Sharing (Quantum Secret Sharing, QSS), Quantum Secure Direct Communication (Quantum Secure Direct Communication, QSDC) Quantum Identity Authentication (Quantum Identity Authentication, QIA) and other aspects of research. Quantum communication is one of the most important applications in the quantum fiel...
