According to the technical scheme provided by the invention, the middle station can generate the hash table for the first hash value, the second hash value and the third hash value, and simultaneously send the corresponding hash table and the second financial data to the data receiving end. Before or at the same time, the central station sends a key instruction to the quantum server, where the key instruction may instruct the quantum server to send the quantum encryption private key to the corresponding data receiving end. After the quantum server receives the key instruction, the corresponding quantum encryption private key can be sent to the data receiving end, the encrypted data and the quantum encryption private key can be sent in a distributed mode, when a certain transmission link is damaged, the encrypted data (second financial data) and the quantum encryption private key cannot be intercepted simultaneously, and the safety of the encrypted data (second financial data) is guaranteed. The number of the data sending ends and the number of the data receiving ends can be multiple, and one data sending end can respectively send corresponding information and data to the multiple data receiving ends based on the middleboxes.

And the data receiving end receives the quantum encryption private key sent by the quantum server. And the data receiving end receives the quantum encryption private key sent by the quantum server. The time when the quantum server sends the quantum encryption private key is not limited in any way, and the quantum encryption private key can be sent to the data receiving end while the quantum encryption public key is sent to the middle station, or the quantum encryption private key can be sent to the data receiving end after the quantum encryption public key is sent to the middle station.
And the data receiving end extracts the first hash value and the second hash value in the hash table, and calculates the first hash value and the second hash value based on a third hash encryption algorithm to obtain a fourth hash value. In general, the data receiving end may calculate the hash values in an order opposite to the order in which the middleboxes produce the hash values. After the data receiving end receives the hash table and the second financial data, the data receiving end firstly calculates the first hash value and the second hash value through a third hash encryption algorithm to obtain a fourth hash value, in the process, the first hash value and the second hash value are combined to obtain a second combined hash value, then the second combined hash value is calculated according to the third hash encryption algorithm to obtain a corresponding fourth hash value, and the accuracy of the first hash value and the accuracy of the second hash value can be verified through the relation between the third hash value and the fourth hash value.
If the fourth hash value corresponds to the third hash value, the first hash value and the second hash value are determined to be correct, and the second financial data are calculated according to a second hash encryption algorithm to obtain a fifth hash value. If the fourth hash value is equal to the third hash value, the fourth hash value is considered to correspond to the third hash value, the first hash value and the second hash value can be considered to be correct, and the authenticity of the second financial data and the authenticity of the first financial data can be verified through the first hash value and the second hash value.

And if the fifth hash value corresponds to the second hash value, the second financial data is determined to be correct, and the received quantum encryption private key is called to decrypt the second financial data to obtain the first financial data. When the fifth hash value corresponds to the second hash value, the data receiving end may consider that the received second financial data is the same as the second financial data sent by the middle station, and at this time, the invention decrypts the second financial data according to the quantum encryption private key to obtain the first financial data.
