In addition, when the user uses the method provided by the application, the user does not need to operate for many times, only needs to send a request for acquiring or uploading information, and does not need to operate for many times.
The hardware encryption mentioned in the application is to use a hardware circuit except the electronic product to be encrypted to communicate with the electronic product to be encrypted, so that the internal program of the product judges whether the program should be continuously executed or not according to the communication data. The hardware encryption can adopt a standard network management protocol or a uniform network management protocol for management.
The present embodiment provides a data sharing and transmitting method, which can be used for data sharing and transmitting, and fig. 1 is a flowchart of a data sharing and transmitting method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S101, after receiving a registration request of a client, acquiring registration identity information of the client, and sending a server public key of a local machine to the client to complete registration; the registration identity information comprises a client public key. After the client sends the registration identity information to the server, the server binds the client public key in the registration information with the client account in the server, and then completes client registration.
Step S102, after receiving a data acquisition request of the client, encrypting the data requested by the client according to the client public key to obtain a request data cipher text, selecting an encryption channel, and sending the request data cipher text to the client through the encryption channel. The encryption channel may select an encryption mode such as hardware encryption or SSH (secure shell protocol). The client public key is generated at the client.
Step S103, after a data transmission request, receiving a data transmission ciphertext transmitted by the client through the encryption channel selected by the client; and the sending data cipher text is obtained by encrypting the data to be sent by the client according to the server public key.
For example, the first office system and the second office system are independent, heterogeneous or covered, and different languages are used for development on different platforms, so that the first office system and the second office system are difficult to directly transmit information. By the aid of the method, the user using the office system A can encrypt the file to be transmitted to the office system B and upload the encrypted file to the server after the user registers in the server, and the server sends the information to the office system B.
Through the steps S101 to S103, the client public key is registered to the server, and after the server stores the client public key, the server can send information to the client by using the client public key, and meanwhile, the client can also send information to the server by using the server public key, so that data sharing and transmission can be realized among different office systems developed by using different languages. For example, after a first client sends data to a server through a server public key, the server sends the data to a second client by using a second client public key, and information exchange is realized among different office systems. In addition, the data sharing exchange between the client and the server adopts ciphertext to transmit in the encryption channel, so that the data security is ensured.
In some optional embodiments, the registration identity information further includes a client ID, a client certificate authentication, and a private key signing challenge code. And after receiving the registration information, the server stores and verifies the book information.
In some optional embodiments, before completing the registration, the method further includes:
and carrying out user identity authentication on the client. The server side can verify the registration information of the client side according to the existing information. The existing information may be payment information of the client, because the service end may be charged, and the service may be provided only after the payment information of the client is verified.
The present embodiment provides a data sharing and transmission method, which can be used for data sharing and transmission, and fig. 2 is a flowchart of a data sharing and transmission method according to another embodiment of the present application, as shown in fig. 2, the method includes the following steps:
step S201, after a client sends a registration request to a server, the server acquires registration identity information of the client according to the registration request and sends a server public key of the server to the client to complete registration; the registration identity information comprises a client public key. The registration information includes a client ID, a client certificate, a private key signature challenge code, and the like. After the client sends the registration identity information to the server, the server binds the client public key in the registration information with the client account in the server, and then completes client registration. In addition, the server stores the registration identity information of the client.
Step S202, after the client sends a data acquisition request to the server, the server receives the data acquisition request of the client, encrypts the data requested by the client according to the client public key to obtain a request data ciphertext, selects an encryption channel, and sends the request data ciphertext to the client through the encryption channel. The encryption channel may select an encryption mode such as hardware encryption or SSH (secure shell protocol).
Step S203, after the client sends a data sending request to the server, the client encrypts the data to be sent according to the server public key to obtain a sending data cipher text, selects an encryption channel to connect, and sends the sending data cipher text to the server through the encryption channel.
In the above steps S201 to S203, by registering the client public key to the server, after the server stores the client public key, the server can send information to the client by using the client public key, and meanwhile, the client can also send information to the server by using the server public key, so that data sharing and transmission can be realized between different office systems developed by using different languages. For example, after a first client sends data to a server through a server public key, the server sends the data to a second client by using a second client public key, and information exchange is realized among different office systems.
In some optional embodiments, the server decrypts and stores the received transmission data cipher text by using the server private key. The server side receives the ciphertext encrypted by the server side public key, namely the data sending ciphertext, and after receiving the ciphertext, the server side decrypts the data sending ciphertext by the server side private key to obtain the plaintext of the data to be sent, and then stores the plaintext of the data to be sent.
In some optional embodiments, the method for data transmission and sharing in the foregoing embodiments further includes:
and after the server decrypts and stores the received sending data cipher text by using the server private key, the client destroys the server public key.
If the server public key is stored in the client all the time, in an actual situation, network security protection of each client is inconsistent, and a client with weak protection is likely to exist, as long as one client is broken, after the server public key is obtained, information security of the whole system cannot be guaranteed, and therefore, the server public key at the client is very necessary to be destroyed. When the client needs to send data to the server next time, the client can resend the request, the server can issue the server public key to the client again, and the process is carried out in the background and cannot be perceived by the user.
In some optional embodiments, the method for data transmission and sharing in the foregoing embodiments further includes:
and after receiving the client public key, the server stores the client public key. And after the server receives the client public key, the client public key cannot be destroyed until the client logs off the account of the client at the server.
In some optional embodiments, after receiving the request data ciphertext, the client decrypts the request data ciphertext by using a client private key. The client private key can be set by a user according to the preference of the user.
In some optional embodiments, after receiving the data sending request of the client, the server verifies the client according to the registration identity information, and after the verification is passed, the server distributes a server public key to the client. The verification may be to verify whether the client is registered in the server and the registered identity is still within the validity period according to the registered identity information of the client.

For example, after a first client sends data to a server through a server public key, the server sends the data to a second client by using a second client public key, and information exchange is realized among different office systems. In addition, the data sharing exchange between the client and the server adopts ciphertext to transmit in the encryption channel, so that the data security is ensured.
