As shown in Figure 3, the handling process of the method comprises the steps:
Step 301, first terminal sends data transfer request by instant messaging application program to server, carries the account identification of object transmission account in this data transfer request.
In force, user can install the instant messaging application program (as micro-letter) with file transmitting function in terminal, when user to need by certain terminal (i.e. first terminal) to other-end (i.e. the second terminal) transfer files, this instant messaging application program can be opened at first terminal and the second terminal, then carry out account at first terminal and the second terminal to log in, user can select at first terminal the file and the object transmission account (account namely the second terminal logged in) that need transmission, click transmission button, first terminal then can receive transfer instruction, then data transfer request can be sent to server, the account identification of object transmission account can be carried in data transfer request, object transmission account can be the account that first terminal this locality logs in, also can be other accounts.
Step 302, server receives the data transfer request that first terminal sends.
In force, first terminal can send data transfer request to server, and server then can receive the data transfer request that first terminal sends, and then can resolve data transfer request, obtains the account identification of object transmission account.
Step 303, server generates the double secret key of transmission data, and this double secret key comprises the first key and the second key.
In force, after server receives the data transfer request of first terminal transmission, a double secret key can be generated in this locality, and record is carried out to this double secret key, this cipher key pair comprises the first key and the second key, first key can to the decrypt data of use second secret key encryption, and the second key also can to the decrypt data of use first secret key encryption.
Step 304, server sends the first key to first terminal, and sends the second key to the second terminal that object transmission account logs in.
In force, server can obtain the information of the terminal logging in object transmission account, i.e. the information of the second terminal, then the second key can be sent to the second terminal, and the first key is sent to first terminal after generating double secret key.It is the situation of the account that first terminal logs in for object transmission account, server can obtain the current information logging in the terminal of the account, first key is sent to first terminal, second key is sent to the other-end (i.e. the second terminal) logging in the account, server can adopt the mode of PUSH message to send key to terminal, and other modes also can be adopted to send key to terminal.
Step 305, the first key that first terminal reception server sends, the second key that the second terminal reception server sends.
In force, after server sends the first key to first terminal, first terminal then can receive the first key, then the first key is stored, same, the second terminal also can receive the second key that server sends, and then stores the second key.
Step 306, first terminal uses the first double secret key data waiting for transmission to be encrypted, and by instant messaging application program, the data after encryption is transferred to the second terminal with terminal data to the mode passed.
