The technical problems posed by the present disclosure will be explained in detail below. It is to be noted that this technical problem is merely exemplary and is not intended to limit the application of the present invention.
The invention provides a method for safely interacting a plurality of groups of terminals, which specifically comprises the following steps as shown in figure 1:
(1) and acquiring communication parameters, such as system, frequency band and the like, of a plurality of terminals for performing coordinated communication.
The method specifically comprises the following steps: after the interactive data sent by each device is obtained, corresponding communication parameters are extracted from the interactive data, wherein the corresponding communication parameters comprise a system and a frequency band.
For example: acquiring communication parameters corresponding to the equipment A as a standard 1 and a frequency band 1;
acquiring communication parameters corresponding to the equipment B as a standard 2 and a frequency band 2;
acquiring communication parameters corresponding to the equipment C as a standard 3 and a frequency band 2;
acquiring communication parameters corresponding to the device D as a standard 1 and a frequency band 1;
and obtaining communication parameters corresponding to the equipment E as a standard 4 and a frequency band 3.
(2) And performing equipment interactive grouping according to the communication parameters, namely dividing the terminals with different parameters into a group A, dividing at least one terminal with different parameters into a group B, and dividing the terminals with all the same parameters into a group C.
The method specifically comprises the following steps: first, a grouping rule is formulated, wherein the specific rule may be, but is not limited to, the following form:
the communication parameters of the group A and the equipment interaction parties are all different, namely the group A and the equipment interaction parties can communicate after conversion of the relay equipment;
group B, communication parameters of two interactive parties of the equipment are at least different, namely communication can be carried out after the conversion of the relay equipment is needed in a specific parameter state;
and C group-equipment interaction communication parameters of both parties are the same, namely, communication can be directly carried out without conversion of the relay equipment.
And then, acquiring the equipment interaction information and the interaction data, and adding a grouping mark to the interaction data corresponding to the current equipment interaction according to the communication parameters.
For example: acquiring a plurality of device interaction information, including:
the equipment interaction information is as follows: the device A and the device D are interacted, and the extracted communication parameters are the system 1 and the frequency band 1 of the device A and the system 1 and the frequency band 1 of the device D;
and equipment interaction information II: the device B interacts with the device C, and the extracted communication parameters are the standard 2 and the frequency band 2 of the device B and the standard 3 and the frequency band 2 of the device C;
and equipment interaction information is three: the device A and the device E are interactive, and the extracted communication parameters are the standard 1 and the frequency band 1 of the device A and the standard 4 and the frequency band 3 of the device E.
Therefore, the interactive data corresponding to the equipment interactive information I is marked as a group C;
the interactive data corresponding to the equipment interactive information II is marked as a group B;
and the interactive data corresponding to the device interactive information III is marked as an A group.
(3) Data required by interaction of each terminal is divided into private data and public interaction data, and different data encryption and transmission modes are used for different groups. And then, after the obtained encrypted private data is decrypted, or the private data is directly merged with the public interactive data, and the terminal data is recovered.
The method specifically comprises the following steps: firstly, private (privacy) important data related to each device are extracted from interactive data corresponding to device interactive information, and the rest data are public interactive data.
And then, according to the grouping mark corresponding to the interactive data, determining whether to encrypt the private data, and determining a specific transmission mode and parameters for transmitting the public interactive data and the private data.
The data encryption and transmission mode is as follows: private data of the group A terminals are transmitted by respective systems and frequency bands without encryption; private data of the group B terminals are transmitted by using different systems or frequency bands without encryption; after the private data of the group C terminals are encrypted, the private data are transmitted by utilizing respective systems and frequency bands.
The specific transmission mode is based on three conditions:
first, in order to prevent each interactive device from receiving private data of the counterpart device.
The transmission mode corresponding to the interactive data marked as the group A is as follows: each device in the control interaction utilizes any one communication parameter to carry out private data transmission, and public interaction data is transmitted through parameter conversion without carrying out encryption of the private data;
the transmission mode corresponding to the interactive data marked as the group B is as follows: controlling each device in the interaction to transmit private data by using different communication parameters, and transmitting public interaction data through parameter conversion without encrypting the private data;
the transmission mode corresponding to the interactive data marked as group C is as follows: and each device in the control interaction encrypts the private data respectively and transmits the private data and the public interaction data together through parameter conversion.
Second, in order to prevent devices of other groups than the respective interactive devices from receiving the private data of the interactive devices.
Since at least one parameter is different between each group, each device in the control interaction utilizes or converts the different parameter to perform private data transmission, and transmits the public interaction data through parameter conversion.
This approach works for each packet.
Thirdly, to prevent devices of the same group other than the respective interactive devices from receiving the private data of the interactive devices.
All parameters among all groups are the same, so that all devices in control interaction respectively encrypt the private data and transmit the private data together with the public interaction data through parameter conversion.
This approach works for each packet.
For example: for the first situation, controlling equipment A and equipment D in equipment interaction information I, respectively encrypting private data, and transmitting the private data and public interaction data together through parameter conversion;
controlling equipment B in equipment interaction information II to perform private data transmission by using a system 2, controlling equipment C to perform private data transmission by using a system 3, and transmitting public interaction data through parameter conversion;
and the equipment A in the third control equipment interactive information utilizes the standard 1 or the frequency band 1 to carry out private data transmission, the equipment E utilizes the standard 4 or the frequency band 3 to carry out private data transmission, and the public interactive data is transmitted through parameter conversion.
For the second case, controlling equipment A and equipment D in equipment interaction information I to perform private data transmission by using a system 1; controlling the device B and the device C in the device interaction information II to carry out private data transmission by using the frequency band 2; and the device A in the third step of controlling the device interactive information converts the communication parameters into a frequency band 3, and performs private data transmission by using the frequency band 3 simultaneously with the device C.
The present invention further provides a relay device, which executes a method for securely interacting multiple groups of terminals, as shown in fig. 2, and specifically includes an information acquisition module, a grouping module, and an encryption transmission module.
The information acquisition module is used for acquiring communication parameters, such as system and frequency band, of a plurality of terminals performing coordinated communication.
The information acquisition module is specifically configured to: after the interactive data sent by each device is acquired, the information acquisition module extracts corresponding communication parameters from the interactive data, wherein the communication parameters comprise a system and a frequency band.
For example: the information acquisition module acquires that the communication parameters corresponding to the equipment A are standard 1 and frequency band 1;
acquiring communication parameters corresponding to the equipment B as a standard 2 and a frequency band 2;
acquiring communication parameters corresponding to the equipment C as a system 3 and a frequency band 2;
acquiring communication parameters corresponding to the device D as a standard 1 and a frequency band 1;
and obtaining communication parameters corresponding to the equipment E as a standard 4 and a frequency band 3.
The grouping module is used for carrying out equipment interactive grouping according to the parameters, namely the terminals with different parameters are divided into a group A, at least one terminal with different parameters is divided into a group B, and the terminals with all the same parameters are divided into a group C.
The grouping module is specifically configured to: firstly, the grouping module makes a grouping rule, wherein the specific rule can be but is not limited to the following form:
the communication parameters of the group A and the equipment interaction parties are all different, namely the group A and the equipment interaction parties can communicate after conversion of the relay equipment;
group B, communication parameters of two interactive parties of the equipment are at least different, namely communication can be carried out after the conversion of the relay equipment is needed in a specific parameter state;
and C group-equipment interaction communication parameters of both parties are the same, namely, communication can be directly carried out without conversion of the relay equipment.
And then, the grouping module acquires the equipment interaction information and the interaction data, extracts the communication parameters of the corresponding equipment, and adds a grouping mark to the interaction data corresponding to the current equipment interaction according to the communication parameters.
For example: the grouping module acquires a plurality of pieces of equipment interaction information, and comprises the following steps:
the equipment interaction information is as follows: the device A and the device D are interacted, and the extracted communication parameters are the system 1 and the frequency band 1 of the device A and the system 1 and the frequency band 1 of the device D;
and equipment interaction information II: the device B interacts with the device C, and the extracted communication parameters are the standard 2 and the frequency band 2 of the device B and the standard 3 and the frequency band 2 of the device C;
and equipment interaction information is three: the device A and the device E are interactive, and the extracted communication parameters are the standard 1 and the frequency band 1 of the device A and the standard 4 and the frequency band 3 of the device E.
Therefore, the grouping module marks the interactive data corresponding to the equipment interactive information as a group C;
marking interactive data corresponding to the equipment interactive information II as a group B;
and marking the interactive data corresponding to the equipment interactive information III as an A group.
The encryption transmission module is used for controlling each interactive device to divide data required by each terminal interaction into private data and public interactive data, and different data encryption and transmission modes are used for different groups. And then, after the obtained encrypted private data is decrypted, or the private data is directly merged with the public interactive data, and the terminal data is recovered.
The encryption transmission module is specifically configured to: firstly, private (privacy) important data related to each device are extracted from interactive data corresponding to the device interactive information of the encryption transmission module, and the rest data are public interactive data.
And then, the encryption transmission module determines whether to encrypt the private data and the specific transmission mode and parameters for transmitting the public interactive data and the private data according to the grouping marks corresponding to the interactive data.
The data encryption and transmission mode is as follows: private data of the group A terminals are transmitted by respective systems and frequency bands without encryption; private data of the group B terminals are transmitted by using different systems or frequency bands without encryption; after the private data of the group C terminals are encrypted, the private data are transmitted by utilizing respective systems and frequency bands.
The specific transmission mode controlled by the encryption transmission module is based on three conditions:
first, in order to prevent each interactive device from receiving private data of the counterpart device.
The transmission mode corresponding to the interactive data marked as the group A is as follows: the encryption transmission module controls each device in the interaction to transmit private data by using any one communication parameter, and transmits public interaction data through parameter conversion without encrypting the private data;
the transmission mode corresponding to the interactive data marked as the group B is as follows: the encryption transmission module controls each device in the interaction to transmit private data by using different communication parameters, and transmits public interaction data through parameter conversion without encrypting the private data;
the transmission mode corresponding to the interactive data marked as group C is as follows: and the encryption transmission module controls each device in the interaction to encrypt the private data respectively and transmits the private data and the public interaction data together through parameter conversion.
Second, in order to prevent devices of other groups than the respective interactive devices from receiving the private data of the interactive devices.
Because at least one parameter is different among the groups, the encryption transmission module controls each device in the interaction to utilize or convert the different parameters to carry out private data transmission, and transmits public interaction data through parameter conversion.
This approach works for each packet.
Thirdly, to prevent devices of the same group other than the respective interactive devices from receiving the private data of the interactive devices.
And the encryption transmission module controls each device in the interaction to encrypt the private data respectively and transmit the private data and the public interaction data together through parameter conversion because all parameters among all the groups are the same.
This approach works for each packet.
For example: for the first situation, the encryption transmission module controls equipment A and equipment D in equipment interaction information I, respectively encrypts private data and transmits the private data and public interaction data together through parameter conversion;
the encryption transmission module controls a device B in the device interaction information II to perform private data transmission by using a system 2, a device C performs private data transmission by using a system 3, and public interaction data is transmitted through parameter conversion;
the encryption transmission module controls a device A in the device interaction information III to perform private data transmission by using a standard 1 or a frequency band 1, a device E performs private data transmission by using a standard 4 or a frequency band 3, and public interaction data is transmitted through parameter conversion.
For the second case, the encryption transmission module controls equipment A and equipment D in equipment interaction information I to perform private data transmission by using a system 1; controlling equipment B and equipment C in the equipment interaction information II to carry out private data transmission by using the frequency band 2; and the device A in the third step of controlling the device interactive information converts the communication parameters into a frequency band 3, and performs private data transmission by using the frequency band 3 simultaneously with the device C.
