Result is asked to be sent to terminal device.
In the present embodiment, the target video conferencing information can be corresponding to be made for video conference information request
Request results, request results corresponding with the solicited message are found according to the solicited message of video conference, such as terminal is set
The standby video request information according to user, the video request information is sent to corresponding server, server is according to the video
Solicited message establishes the connectivity port of connection corresponding to finding, and the port is sent into terminal device, so as to the end
End equipment is successfully established video conference, and the symmetric key sent in transmitting procedure by terminal device is encrypted, so as to
On the premise of the safety of video conference information is ensured, the encryption efficiency of video conference is improved.
The schematic flow sheet of video conference information transfer as shown in Figure 3, terminal device receive video conference request letter
Breath, symmetric key is generated according to video conference solicited message, solicited message and symmetric key are entered into RSA public key encryptions generation first
Ciphertext, and first ciphertext is sent to server, server is decrypted according to RSA private keys according to the first ciphertext of reception, obtained
Solicited message and symmetric key are taken, and will be encrypted according to the request results of solicited message by symmetric key, and will encryption
Information afterwards is sent to terminal device.
Step S40, the terminal device receive the second ciphertext of the server feedback, pass through the default symmetric key
Second ciphertext is decrypted, obtains the target video conferencing information.
It should be noted that second ciphertext can be the request knot that server is judged according to video conference information
Fruit, the request results is carried out the ciphertext of symmetric cryptography, or the video conference port of matching is encrypted, and by port
Information is sent to the terminal device, so as to make terminal device establish video conference according to the port information.
In the present embodiment terminal device by using Hybrid Encryption mode, on the premise of data high security is ensured,
Improve the efficiency of video conference information encryption.
Further, as shown in figure 4, proposing that video conference information transferring method second of the present invention is real based on first embodiment
Example is applied, in the present embodiment, after the step S10, methods described also includes：

Example is applied, in the present embodiment, before the step S20', methods described also includes：
Step S203', the server receive store instruction, are stored the asymmetric privacy keys according to the store instruction
In local.
It should be noted that in the technology of data encryption, need to be provided with public key and private key for asymmetric encryption mode,
And during AES encryption, as long as there is AES key to carry out plus decode to data, and in unsymmetrical key, then must have
Public key could carry out encryption and decryption with private key, it is seen that for unsymmetrical key, the encryption that data are completed by two sets of keys shows
So than only needing the cryptographic security that a set of key is completed high.
In order to realize the cipher mode of high security, prestore asymmetric public key in terminal device, is prestored in server end
Asymmetric privacy keys, so as to complete the asymmetric encryption of data, improve security of the data in transmitting procedure.
In the specific implementation, the server by receiving store instruction, in the present embodiment, the store instruction be
The command information of asymmetric privacy keys is stored in local, asymmetric privacy keys can be stored in server end by the command information, so as to
It can be achieved that the ciphertext that terminal device is sent is decrypted, so as to obtain the video conference solicited message after decryption.
The present embodiment receives store instruction by server, is prestored by the store instruction in local asymmetric privacy keys,
So as to realize to data plus decoding, the security of data transfer is improved.

First summary info is sent to server with the data to be transmitted after encryption, so that the server is non-right according to what is locally prestored
Claim private key that first ciphertext is decrypted, the video conference solicited message is obtained, by the video conference solicited message
Be encrypted generation the second summary info, first summary info is matched with second summary info, according to
The step of target video conferencing information is searched according to the video conference solicited message is performed with result.
Further, following operation is also realized when the video conference message transmission procedure is performed by first processor：
The terminal device triggers key generation instruction according to the video conference solicited message, is generated according to the key
Instruction generates the default symmetric key, and the default symmetric key is stored in into local.
In the present embodiment terminal device by using Hybrid Encryption mode, on the premise of data high security is ensured,
Improve the efficiency of video conference information encryption.
In addition, the embodiment of the present invention also proposes a kind of storage medium, video conference information is stored with the storage medium
Program is transmitted, following operation is realized when the video conference message transmission procedure is performed by second processor：
The first ciphertext that server receiving terminal equipment is sent；
First ciphertext is decrypted according to the asymmetric privacy keys locally to prestore for the server, obtains video conference
Solicited message and default symmetric key；
The server searches target video conferencing information according to the video conference solicited message, according to described default pair
Claim key that the target video conferencing information found is encrypted, obtain and feed back the second ciphertext, so that the terminal device
The second ciphertext of the server feedback is received, second ciphertext is solved by the default symmetric key locally generated
It is close, obtain the target video conferencing information.
Further, following operation is also realized when the video conference message transmission procedure is performed by second processor：
The server video conference solicited message is encrypted the second summary info of generation；
The server receives the first summary info that the terminal device is sent, by first summary info with it is described
Second summary info is matched, and perform the server according to matching result searches mesh according to the video conference solicited message
Video conference information is marked, the target video conferencing information found is encrypted according to the default symmetric key, is obtained simultaneously
The step of feeding back the second ciphertext.
Further, following operation is also realized when the video conference message transmission procedure is performed by second processor：
The server receives store instruction, and the asymmetric privacy keys are stored in into local according to the store instruction.
Server on the premise of data high security is ensured, carries by using the mode of Hybrid Encryption in the present embodiment
