In the embodiment of the application, the control end can also be called a management end or a signaling server, and is used for carrying out signaling interaction with the client to transfer necessary information required by connection establishment between the clients, and meanwhile, the control end is used for acquiring the subscription relation of the client and sending instructions to the client and the SFU server to determine the producer and the consumer based on the subscription relation. The control end in the embodiment of the application is used as a middleman to help the two parties to establish connection under the condition of exposing privacy as little as possible. The communication manner between the control end and the client and the SFU server may use any manner, for example, webSocket or XMLHttpRequest, etc. to exchange token information with each other, and embodiments of the present application are not limited thereto.

The SFU server may receive instructions from the control side to manage the producer and consumer objects and may then decide whether to receive and/or send audio and/or video streams of the real-time communication from the client. It should be understood that the SFU server may also be called as an SFU or a forwarding server or a media forwarding server, and several calls of the SFU server may be replaced if not specifically described hereinafter, which is not limited by the embodiment of the present application. It should be understood that in the present application, the control end and the SFU may be two independent devices, or may be integrated on one device.

It should be understood that, in the embodiment of the present application, the client may also be referred to as a user side, a user device, or a terminal device, and in the real-time embodiment of the present application, the terminal device may be installed with a browser, and may perform real-time communication through the browser, or be installed with an APP or an applet, and perform real-time communication through the APP or the applet.

It should be understood that in the video conference system scenario shown in fig. 1, only two clients are illustrated, but the embodiments of the present application are not limited thereto, and in an actual real-time communication scenario, the number of clients may include any number, for example, 10, 50, 500, 5000, etc. according to the actual situation.

In order to prevent data loss caused by network faults and other factors in a conference system, a client needs to locally store conference related data, and in order to ensure the safety of the local storage, the client generally needs to encrypt and store the data. The existing client encryption scheme generally uses AES or DES symmetric encryption, and can also use base64 bit coding, and direct storage is realized after coding; however, the information after base64 encoding is about 1/3 larger than the original information, so that the space required for storage is larger than the original information; because AES and DES are symmetric encryption algorithms, relatively complex operations such as rectangular changes are involved, and files after encryption are also relatively large; meanwhile, the number of the encryption operations is relatively large, and the operation time and occupied space are relatively large.

In order to solve the problems in the prior art, the embodiment of the application provides a method for encrypting conference related data, which selects an encryption character according to time, uses the encryption character to perform bitwise exclusive-or operation on data to be processed to obtain encrypted data or decrypted data corresponding to the data to be processed, and can encrypt the data only by bitwise exclusive-or operation.

In the following, for ease of understanding and explanation, by way of example and not limitation, the execution process and actions of the method of real-time communication of the present application in a real-time communication system will be described.

A method for processing conference related data according to an embodiment of the present application is exemplarily described below with reference to fig. 2.

The method shown in fig. 2 is applied to a client in a real-time video conference system as shown in fig. 1 or a client in any other communication system, and the method shown in fig. 2 includes:

210, obtaining encryption time.

It is to be understood that the encryption time may be a time at which data is saved, or a preset time, for example, may be a time determined according to the saved time. For example, the encryption time is a time determined according to a time of encrypting the save data and a preset rule, for example, the preset rule is as follows: the encryption time is one of time points with continuous intervals of 5 minutes, for example, one of time points of 3:05 and 3:10 …, and the actual encryption time may be a preset time point nearest to the save time, for example, the save time is 3:06, and the encryption time is 3:05. Alternatively, the encryption time determination rule may be other rules, for example, the encryption time may be a time determined at two preset time points adjacent to the save time, for example, an intermediate time point between two adjacent time points, or the like. For example, the preset rule is a table with a preset correspondence between a save time and an encrypt time, where the encrypt time is an encrypt time corresponding to the save time determined by looking up a table, and the embodiment of the application is not limited thereto.

In practical application, after data encryption, the encrypted data and the time for storing the data can be stored, and when decryption, the encryption time is determined according to the time for storing the data. In correspondence with the above description, one case is that the encryption time is the time of saving the data, and the other case is that the encryption time is a time determined according to the time of saving the data. The specific determination method may correspond to the description in the previous paragraph, and will not be described herein. In the second case, since the encryption time and the data storage time are different, the data security can be improved, and even if the data storage time is stolen, the encryption time cannot be acquired and the data cannot be decrypted without knowing the rule, and the data security can be improved.

Alternatively, as an embodiment, the conference related data processed by the client in the embodiment of the present application may be any data that needs to be stored locally and related to the conference, for example, the video conference related data includes: at least one of historical meeting information, meeting account numbers, account passwords, meeting records and last meeting option information.

220, Performing operation according to the encryption time to obtain an operation result.

It should be understood that, in the embodiment of the present application, the encryption time may be calculated in a plurality of ways, so long as a unique encrypted string can be selected from the strings after the calculation.

For example, the operation may be a positive selection or a cosine operation.

As one embodiment, the calculating according to the encryption time to obtain an operation result includes:

Performing sine operation on the encryption time to obtain an initial value;

performing multiple rounding operation on the absolute value of the initial value to obtain the operation result;

Specifically, the application can ensure that the selected value is between-1 and 1 through mathematical function sin calculation, so that the random number is selected according to encryption time, sin removal operation is carried out, the obtained value is ensured to be a positive number by absolute value, then ten times is multiplied, and then the whole is obtained, and the obtained value, namely, the operation result is any number between 0 and 10. It should be understood that here, the multiple operation is multiplied by ten, and the corresponding character string may include 11, and the corresponding character is selected from the character string for data processing according to the operation result.

Alternatively, in practical application, the multiple operation may also be other values, for example, may be 20, 50, or 100, and the length of the corresponding string may also be correspondingly increased, for example, 21, 51, or 101.

230, Selecting an encrypted character from the encrypted character string according to the operation result.

After the operation result is determined, the corresponding encrypted character can be selected from the character string according to the result. For example, a character corresponding to the operation result is selected from the encrypted character string as the encrypted character. For example, if the operation result is 5, a character corresponding to 5 may be selected from the encrypted character string as the encrypted character, for example, the character string includes 11 characters in total of 0 to 10, and a character corresponding to 5, that is, the 6 th character from 0, is selected as the encrypted character.

The above describes a scheme of selecting only one encrypted character for data processing. In practical applications, a plurality of encrypted characters may be selected for multiple encryption or decryption processes.

Optionally, as an embodiment, the selecting, from the encrypted character string, a character corresponding to the operation result as the encrypted character includes:

And selecting a plurality of characters from the encrypted character string in sequence by taking the operation result as a starting point to serve as the encrypted characters.

It will be appreciated that if the number of characters selected exceeds the string length, the corresponding number of characters is sequentially removed from the beginning of the string. For example, the character string length is 11, including characters 0-10, the operation result is 10, 4 characters (i.e. 4 exclusive-or operations are performed) are needed to be used for encryption or decryption, and the 4 selected characters are character 9, character 10, character 0 and character 1.

According to the embodiment of the application, the data security can be improved through multiple times of encryption.

It should be understood that there may be only one encryption string in the embodiment of the present application, and the encryption string may be preset. Or in the embodiment of the application, a plurality of encryption character strings can be also provided, and one character string can be selected from the plurality of encryption character strings for encryption during actual encryption or decryption. For example, one character string may be selected from a plurality of encrypted character strings according to the encryption time, and then the encrypted character may be selected from the selected encrypted character strings according to the encryption time.

Correspondingly, as an embodiment, before selecting the encrypted character from the encrypted character string according to the operation result, the method further includes:

The encryption string is selected from a plurality of preset strings.

Optionally, the selecting the encrypted string from a plurality of preset strings includes:

And selecting the encryption character string from the plurality of preset character strings according to the selection operation result of the encryption time.

It should be understood that there may be various selection results, as long as one character string can be selected from the plurality of character strings after the operation according to the encryption time. The embodiments of the present application are not limited in this regard.

And 240, performing bit exclusive OR operation on the data to be processed by using the encrypted character to obtain encrypted data or decrypted data corresponding to the data to be processed, wherein the data to be processed comprises video conference related data.

It should be understood that in the embodiment of the present application, the data to be processed may be data before encryption, in which case, in the embodiment of the present application, the data is encrypted; alternatively, the data to be processed may be encrypted data, in which case the data is decrypted in the embodiment of the present application.

Correspondingly, as an embodiment, when the data to be processed is data to be encrypted, the encrypted character is used to perform bit exclusive or operation on the data to be processed to obtain encrypted data which is the data to be processed;

And when the data to be processed is encrypted data, performing bit exclusive OR operation on the data to be processed by using the encrypted character to obtain decrypted data of the data to be processed.

Specifically, after the encrypted character is determined, bitwise exclusive-or operation is performed on the data to be processed. When the bit of the encrypted character is smaller than the data to be processed, the bit exclusive or transportation is required to be carried out after the filling. For example, the data to be processed is 64 bits, and the encrypted character is 8 bits, and the encrypted character needs to be complemented by 64 bits and then subjected to bit exclusive or operation, where the complemented bits may be all 1 bits or all 0 bits, or the complemented bits may be performed according to a preset rule, for example, the complemented bits may be complemented according to an alternating sequence of 0, 1 or 1 and 0 bits, or the complemented bits may be performed according to other rules, and the embodiment of the present application is not limited thereto, as long as the same bit complemented rule is adopted when encrypting and decrypting.

Further, as another embodiment, when selecting a plurality of encrypted characters to perform the bitwise exclusive-or operation, the plurality of encrypted characters may be subjected to the bitwise exclusive-or operation one by one, and the result of the last operation is the final result. If the number of bits is insufficient, the bit-wise exclusive OR operation can be performed first and then with the description of the upper position.

Correspondingly, as an embodiment, the performing bitwise exclusive-or operation on the data to be processed by using the encrypted character to obtain encrypted data or decrypted data corresponding to the data to be processed includes:

and carrying out bit-wise exclusive-or operation on the data to be processed one by one according to the sequence of the plurality of characters, wherein the result of the previous bit-wise exclusive-or operation is used for carrying out the bit-wise exclusive-or operation on the next character, and after the last character bit-wise exclusive-or operation, obtaining the encrypted data or the decrypted data corresponding to the data to be processed, wherein the character sequence of the bit-wise exclusive-or operation corresponding to the obtained encrypted data is opposite to the character sequence of the bit-wise exclusive-or operation corresponding to the obtained decrypted data.

For example, when determining that the plurality of characters are A, B, C, performing a bitwise exclusive-or operation on the data to be encrypted by using a when performing the encryption sequence, then obtaining a first result, performing a bitwise exclusive-or operation on the first result by using B, obtaining a second result, and performing a bitwise exclusive-or operation on the first result by using C, thereby obtaining the encrypted data. Then, when decrypting again, the bit exclusive-or operation is performed according to the reverse order, namely according to the order C, B, A, namely, the bit exclusive-or operation is performed on the encrypted data by using the C to obtain a second result, the bit exclusive-or operation is performed on the second result by using the B to obtain a first result, and then the bit exclusive-or operation is performed on the first result by using the A to obtain decrypted data.

The embodiment of the application adopts the mode of bit exclusive OR to encrypt or decrypt the data, so as to realize the information needed by encryption; after exclusive-or one character, exclusive-or operation is carried out once again, so that the original character can be obtained; therefore, the simple encryption and decryption can be realized by only ensuring that the exclusive or characters are the same each time, the scheme has small calculated amount and fast operation, only needs to traverse the data to be encrypted once, and occupies less memory compared with the prior art.
