Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] like figure 1 The present invention shown is composed of a client, an authentication server and a network connecting the two, and the client and the authentication server are connected through respective quantum gateways, and there are two channels between the quantum gateways, that is, the quantum channel and the classical Channels, quantum channels are used to distribute quantum keys, and classical channels are used to transmit classical information other than quantum keys. The client and the authentication server not only have their own quantum gateways, but also have their own quantum key generation control servers, quantum key storage management servers, encryption algorithm libraries, and hash algorithm libraries. The authentication server also has an authentication server and a user information database for storing user informati...

Abstract

The invention discloses a system and a method for authenticating identity based on a quantum key. The system comprises a user side, an authentication server side, a quantum network and a classic network. The method comprises the steps of using a plain text for identity authentication and a quantum key K1 in a traditional technology as a plain text for each authentication after serially combining the plain text with the quantum key K1; firstly, carrying out abstract extraction on the plain text; secondly, encrypting an abstract of the plain text by using an encryption algorithm; finally, transmitting an encrypted ciphertext to the authentication server side. According to the method for authenticating the legal identity of a user by applying the quantum key, provided by the invention, the authentication of the system on the legal identity of the user is realized, and transmission of data needed for authentication in a network is absolutely safe.

Description

technical field [0001] The invention belongs to the field of quantum communication, and in particular relates to a quantum key-based identity authentication system and method. Background technique [0002] As human society enters into informatization, people communicate more and more frequently, people's demand for information is increasing day by day, and the acquisition and release of information has penetrated into everyone's daily life. But at the same time, various incidents of information leakage and illegal access to information continue to occur, which makes information security increasingly the focus of attention. [0003] Communication security is not only the primary concern of both communication parties, but also the most prominent security issue in the information society. Verifying the legal identity of users is the first guarantee to ensure communication security. The existing identity authentication mechanism generally adopts the verification mechanism of u...
