Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0057] The quantum key-based data sharing method provided by this application can be applied to such as figure 1shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The terminal 102 sends a data sharing request to the server 104. When the server 104 receives the data sharing request uploaded by the terminal 102, it performs identity authentication based on the authentication quantum key. When the identity authentication passes, it obtains and stores the quantum key to encrypt the target data The obtained ta...

Abstract

The present application relates to a quantum key-based data sharing method, device, computer equipment and storage medium. The method includes: when receiving a data sharing request uploaded by a terminal, performing identity authentication based on an authentication quantum key to obtain an identity authentication result; The text data is obtained by encrypting the target data requested by the data sharing request by storing the quantum key; performing ciphertext conversion on the target storage ciphertext data through the corresponding transmission quantum key of the terminal to obtain the transmission ciphertext data; the transmission ciphertext data Send it to the terminal, so that the terminal can obtain the target data after decrypting the transmission ciphertext data according to the transmission quantum key. By adopting the method, the security of data sharing can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a quantum key-based data sharing method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, various network applications enable people to obtain rich data resources through data sharing, such as obtaining news data, social data, transaction data and other application data. With the wide application of data sharing, ensuring the security of data in data sharing has gradually become the focus of technological development. [0003] At present, in the traditional data sharing process, the shared data is usually encrypted with a key pair composed of a public key and a private key, and the shared data is transmitted through encrypted ciphertext. However, the length of the key pair composed of the public key and the private key is generally limited, and there is a risk of being cracked by brute force, re...
