In the interactive shared electronic whiteboard encryption method, the key negotiation and interactive encryption are carried out through the interaction of the electronic whiteboard management module, the video terminal module and the video platform, so that the safe transmission of the shared electronic whiteboard during the interaction is realized, and the key documents of a user are prevented from being stolen. And the encryption process of the first interactive data of the electronic whiteboard management module is carried out in the video terminal module with the data processing capability in the same local area network, so that the data security can be ensured, the data processing burden of the electronic whiteboard management module is reduced, the hardware performance of the electronic whiteboard management module is not required to be considered, and the cost is reduced.
In a variation of fig. 1, as illustrated in fig. 2, in addition to the steps S110 to S130 illustrated in fig. 1, the method further includes:
step S140: and the electronic whiteboard management module receives second interactive data encrypted by the video platform according to the key negotiation result.
Step S150: and the electronic whiteboard management module decrypts the second interactive data according to the key negotiation result and sends the decrypted second interactive data to the electronic whiteboard.
In the embodiment shown in fig. 2, steps S140 and S150 follow step S130. In such embodiments, the second interaction data is generated from the first interaction data. Specifically, for example, the video platform may combine the first interactive data with other data to form second interactive data; the video platform may encrypt the first interactive data and send the encrypted first interactive data to other electronic whiteboards, and receive second interactive data generated by other electronic whiteboards based on the first interactive data (the first interactive data is displayed on other electronic whiteboards, and a user interacts with the first interactive data to generate second interactive data after watching the first interactive data), and so on.
In other embodiments, steps S140 and S150 may be performed after step S110, and in such embodiments, the second interactive data may be independent of the first interactive data, for example, the second interactive data is sent to the video platform by another electronic whiteboard, and sent to the electronic whiteboard management module by the video platform, and then forwarded to the local electronic whiteboard for display.

The video platform 201 may include a key agreement module 210, a platform encryption module 202, and an electronic whiteboard server 203 (fig. 3 shows that the video platform 201 and the electronic whiteboard server 203 are independent from each other, meaning that they may be physically independent devices; the electronic whiteboard server 203 may also be integrated into the video platform 201). The electronic whiteboard server 203 is used for data interaction with the electronic whiteboard management module 204. The key agreement module 210 is used to negotiate keys with the video terminal module 205. The key agreement module 210 is optionally an SSL server.

The video terminal 209 is for managing data communication inside and/or outside the video terminal module 205. After the key negotiation module 208 negotiates a key with the key negotiation module 210 of the video platform, the key negotiation result may be sent to the terminal encryption module 205 through the video terminal 209. The terminal encryption module 206 is configured to encrypt data to be sent to the electronic whiteboard management server 203 according to the key agreement result and decrypt data to be sent to the electronic whiteboard management module 204 according to the key agreement result. The terminal encryption module 206 may encrypt and decrypt the transmitted data using, for example, a negotiated symmetric encryption algorithm. The symmetric encryption algorithm may be AES, DES, SM1 cryptographic algorithm.
Each electronic whiteboard management module 204 is associated with a video terminal module 205 of the same local area network. Each electronic whiteboard management module 204 performs the steps shown in fig. 1 or fig. 2.
A specific embodiment of the present invention will be described below with reference to fig. 4.
First, in step S301, the electronic whiteboard management module 204 sends a conference entry request to the video terminal 209.
In step S302, the video terminal 209 sends a key request to the key agreement module 208 of the video terminal module 205.
In steps S303 and S304, the key agreement module 208 of the video terminal module 205 performs SSL key agreement with the key agreement module 210 of the video platform 201.
In step S305, the key agreement module 208 of the video terminal module 205 feeds back the key information (i.e., the key agreement result) to the video terminal 209.
In step S306, the key agreement module 210 of the video platform 201 feeds back the key information (i.e., the key agreement result) to the platform encryption module 202.
The execution sequence of step S305 and step S306 is not limited to this, and step S305 and step S306 may be performed in parallel, or step S306 may be performed first and then step S305 may be performed.
In step S307, the video terminal 209 sends a message that the key agreement is successful to the electronic whiteboard management module 204.
In step S308, the video terminal 209 feeds back the key information to the terminal encryption module 206.
The execution sequence of step S307 and step S308 is not limited to this, and step S307 and step S308 may be performed in parallel, or step S308 may be performed first and then step S307 may be performed.
In step S309, the electronic whiteboard management module 204 sends a data interaction notification to the electronic whiteboard 207.
In step S310, the electronic whiteboard 207 interacts with the user, and sends the first interaction data to the electronic whiteboard management module 204.
In step S311, the electronic whiteboard management module 204 sends the first interaction data to the terminal encryption module 206 to encrypt the data according to the key agreement result.
In step S312, the terminal encryption module 206 returns the encrypted first interactive data to the electronic whiteboard management module 204.
In step S313, the electronic whiteboard management module 204 sends the encrypted first interactive data to the electronic whiteboard server 203.
In step S314, the electronic whiteboard server 203 sends the encrypted first interaction data to the platform encryption module 202 for decryption according to the key agreement result.
In step S315, the platform encryption module 202 sends the decrypted first interactive data to the electronic whiteboard server 203.
The above steps show that the process of encrypting and decrypting data sent by the electronic whiteboard 202 to the electronic whiteboard server 203 is opposite to the process of sending data encrypted and decrypted by the electronic whiteboard server 203 to the electronic whiteboard 202. Specifically, taking the second interactive data as an example, the electronic whiteboard server 203 receives the second interactive data decrypted according to the key negotiation result of the electronic whiteboard management module 204 that sends the second interactive data, and sends the second interactive data to the platform encryption module 202, so as to encrypt the second interactive data according to the key negotiation result of the electronic whiteboard management module 204 that is to receive the second interactive data. The platform encryption module 202 returns the encrypted second interactive data to the electronic whiteboard server 203, the electronic whiteboard server 203 sends the encrypted second interactive data to the electronic whiteboard management module 204 which is to receive the second interactive data, and the electronic whiteboard management module 204 sends the encrypted second interactive data to the terminal encryption module 206 of the associated video terminal module 205 to decrypt according to the key negotiation result of the video terminal module 205. The terminal encryption module 206 sends the decrypted second interactive data to the electronic whiteboard management module 204, and the electronic whiteboard management module 204 sends the decrypted second interactive data to the corresponding electronic whiteboard 207 for interactive display.
In the interactive shared electronic whiteboard encryption system provided by the embodiment of the invention, key negotiation and interactive encryption are carried out through the interaction of the electronic whiteboard management module, the video terminal module and the video platform, so that the safe transmission of the shared electronic whiteboard during the interaction is realized, and the key documents of a user are prevented from being stolen.
