However, in this way, when a certain interphone of the other groups adjusts the channel to be the a channel, the voice information sent by the server can also be received.

Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As can be seen from the description of the background art, the interphone will generally preset a plurality of channels, and in the related art, the interphone in the same communication cluster may be preset to use the same communication channel, so that when the server side receives the communication data, the server side may forward the communication data according to the communication channel to the interphone in the same communication channel, thereby implementing communication interaction between the interphones in the same communication channel.
However, in some scenarios, it may be desirable that only certain users can receive communication data, and no other users receive communication data (i.e., it may be desirable that only interphones within the same communication cluster can interact with information, but not interphones of the same communication cluster cannot interact with information). For example, during field training activities, the training staff may be grouped, and it is desirable to communicate between users in the group, while communication between users in different groups is not desirable, in which case the solution in the related art is difficult to implement. The server determines to transmit the data in the corresponding channel according to the channel corresponding to the received data, so that the interphone in the same channel can receive the information, and at the moment, when the interphone is adjusted to the same channel by the user preset as different groups, the transmitted data can be received.
For example, when the group a and the group B play a field training game, the members of the group a use the interphone to communicate on the channel a, and the members of the group B use the interphone to communicate on the channel B, and if a certain member of the group a uses the interphone on the channel B, communication data between the members of the group B may also be received.
That is, the communication method in the related art cannot guarantee the communication security between clusters.
In the embodiment of the disclosure, the interphone performs grouping of communication clusters in advance, quantum session key sets among different communication clusters are different, when the interphone needs to send data, a certain quantum session key in the pre-stored quantum session key set can be used for encrypting the data needing to be sent, so that ciphertext information is obtained, and thus communication equipment among different communication clusters cannot decrypt the encrypted ciphertext information, and the safety of communication equipment among the same communication clusters in the information interaction process is ensured.
Referring to fig. 1, fig. 1 is a schematic flow chart of an intercom encrypted communication method provided by an embodiment of the present invention, where the intercom encrypted communication method may be applied to a first intercom in a first communication cluster, a plurality of intercoms in the first communication cluster all include the same quantum session key set, the quantum session key sets included in the intercoms in different communication clusters are different, and each intercom is connected with a server in a communication manner.
It should be noted that, in the actual use process, there may be a plurality of communication clusters, in this embodiment, only the communication of one of the plurality of communication clusters is described, and the communication modes adopted by other communication clusters in the plurality of communication clusters may be the same as the communication mode disclosed in this embodiment, so that the communication mode of one of the communication clusters (the first communication cluster) is selected in this disclosure to describe in detail, so as to facilitate understanding the data transmission process of the interphone in the communication cluster of this disclosure.
It should be understood that the number of interphones in each communication cluster may be different, and the number of interphones in each communication cluster may be defined according to practical situations.
It should be noted that, quantum session key sets included in the interphones in different communication clusters are different, for example, the communication cluster a includes An interphone A1 and An interphone a2. The interphone A1 and the interphone A2 are respectively a quantum session key set A, the interphone B1 and the interphone B2 are respectively a quantum session key set B, and the quantum session key set A and the quantum session key set B can be different, so that after the quantum session key in the quantum session key set A encrypts ciphertext information A obtained by encrypting data, the quantum session key in the quantum session key set B can not decrypt the ciphertext information A, and correspondingly, the quantum session key in the quantum session key set A can not decrypt the ciphertext information obtained by encrypting the quantum session key in the quantum session key set B. In this way, communication equipment among different communication clusters cannot interact, so that the safety of the preset interphone among the same group of communication clusters in the information interaction process is ensured.
As shown in fig. 1, the method for encrypting communication by the interphone can include the following steps:
step 101, in response to receiving first data to be transmitted, encrypting the first data by using a first quantum session key in a quantum session key set included in a first interphone to obtain a first ciphertext;
step 102, based on the identifier corresponding to the first quantum session key and the first ciphertext, generating first transmission data, and sending the first transmission data to the server.
The server is used for sending the first transmission data to the second interphone.
Wherein the second interphone comprises any one of the following:
Interphone except the first interphone in the first communication cluster;
an intercom that is in the same communication channel as the first intercom.
It should be understood that the service side may determine, in advance, the communication cluster in which the first interphone is located, so as to implement that the first transmission data is sent to some interphones in a directional manner, in this way, the first transmission data may be prevented from being sent to the interphones that do not belong to the first communication cluster, and the interphones that are in the predefined same communication cluster may not use the same communication channel for communication.
As an example, after the communication clusters are determined in advance, the interphone in the same communication cluster should use the same channel, so that the interphone in the same communication channel as the first interphone may be directly determined as the second interphone, and thus, the server may not need to store the interphone corresponding to each communication cluster, but only need to directly transmit according to the communication channel. Meanwhile, the method also ensures that the server is not required to be notified every time the predefined communication cluster is changed, and the server only needs to perform corresponding forwarding work according to the communication channel, so that the whole flow is simpler.
As an example, the quantum session key may be understood as a session key generated based on a quantum random number and a quantum key distribution protocol, and a ciphertext obtained after data encryption by using the quantum session key, so that the ciphertext has a certain capability of resisting cracking of a quantum computer, thereby being beneficial to making the ciphertext obtained after data encryption by using the quantum session key safer.
As an example, the quantum session key set may include a plurality of quantum session keys, so that different quantum session keys may be used in each information transmission process, and thus, a large number of times of cracking may be required for data in an interaction process, and it may also be understood that, since each piece of information is encrypted by using a different quantum session key, cracking is required from scratch for each piece of ciphertext data, which obviously greatly increases cracking difficulty, and thus, the encrypted communication process may be safer.
As an example, the quantum session key sets included by the walkie-talkies in different communication clusters may be different, it being understood that the same quantum session key is not included in different quantum session key sets. In this way, different communication clusters can be made incapable of decrypting each other.
As an example, the first interphone includes a quantum session key set, so that the first interphone includes a plurality of quantum session keys, one quantum session key can be determined from the quantum session key set and is determined to be the first quantum session key, and the identifier corresponding to the first quantum session key and the first ciphertext can be combined and packaged to generate first transmission data, so that after the server sends the first transmission data to the second interphone, the second interphone can efficiently determine the first quantum session key in the first quantum session key set according to the identifier corresponding to the first quantum session key, thereby realizing efficient decryption of the first ciphertext.
As an example, the first intercom may have a plurality of transmission channels, and the first transmission channel may be a predefined transmission channel. Correspondingly, interphones which are located in the same transmission channel with the first interphone can be understood as the same communication cluster, and the interphones and the first interphone have the same quantum session key set, so that the server side can send first transmission data to the interphones which are located in the first transmission channel except the first interphone, and the interphones which are located in the first transmission channel except the first interphone can decrypt the first ciphertext by utilizing the first quantum session key in the first quantum session key set, thereby obtaining the first data.
In the disclosure, after determining the first data to be transmitted, the first interphone may encrypt the first data by using a first quantum session key in the first quantum session key set, so as to obtain a first ciphertext, and may generate first transmission data according to an identifier corresponding to the first quantum session key and the first ciphertext, and may transmit the first transmission data to the server. Because the first interphone comprises a plurality of quantum session keys, and one quantum session key is selected from the plurality of quantum session keys for encryption, the selection of the quantum session keys has randomness, so that the cracking difficulty is increased, and the encryption transmission process can be safer. And the server sends the first transmission data to the second interphone, if the second interphone of the received first transmission data is not divided into the same communication cluster with the first interphone in advance, the first data can not be obtained obviously because of the absence of the first quantum session key. Meanwhile, the first ciphertext in the first transmission data is obtained by encrypting the first quantum session key, so that the first ciphertext is difficult to crack.
That is, the communication interaction between interphones which perform network communication by using the server is safer by the method disclosed by the invention.
In some embodiments, the first quantum session key is used no more than a preset number of times.
As an example, the preset number may be 2 or 1. That is, it can be understood that the first quantum session key is used only a small number of times.
As an example, the number of uses of the first quantum session key as the encryption key may be understood as the number of times of encryption or decryption with the first quantum session key. That is, in the process of communication of each interphone in the communication cluster, one interphone uses one quantum session key for encryption, and then the other interphone uses the quantum session key for decryption. Thus, the number of times a quantum session key is used can be understood as the number of times the quantum session key is used by one interphone for encryption or decryption. For example, when the preset number is 2, the first quantum session key is used at most twice for encryption or decryption, or used for encryption and decryption once, so that a plurality of different quantum session keys can be used in a plurality of data interaction processes in the communication process, and the difficulty of cracking the interaction data can be increased.
As an example, the number of quantum session keys in the quantum session key set may be set according to the actual situation. For example, in some scenarios, the communication devices in the communication cluster may need frequent dialogue communication, and the number of quantum session keys in the quantum session key set may be set to be much larger, and correspondingly, in the case where the communication devices in the communication cluster dialogue less frequently and only need to dialogue for a short time, the number of quantum session keys in the quantum session key set may be set to be smaller.
It should be understood that a quantum session key set may be understood as a string of a number of characters, while a quantum session key may be understood as part of the string. For example, a quantum session key set is a string of 10 ten thousand characters, where every 16 consecutive characters constitutes a quantum session key.
Referring to fig. 2, fig. 2 is a flow chart of a method for encrypting communication of interphones, which is provided by the embodiment of the invention, and is applied to a server, wherein the server is in communication connection with a plurality of interphones, the plurality of interphones are divided into at least one communication cluster, quantum session key sets included in the interphones belonging to the same communication cluster are the same, and quantum session key sets included in the interphones belonging to different communication clusters are different.
As shown in fig. 2, the method for encrypting communication by the interphone may include the following steps:
step 201, in response to receiving first transmission data sent by a first interphone in a first communication cluster, determining a second interphone based on a first transmission channel adopted by the first interphone to send the first transmission data;
step 202, the first transmission data is sent to the second interphone.
The first transmission data are used for being generated by the first interphone in a mode that the first data are encrypted by using a first quantum session key in a quantum session key set included in the first interphone to obtain a first ciphertext, and the first transmission data are generated based on an identifier corresponding to the first quantum session key and the first ciphertext.
It should be understood that the process of generating the first transmission data by the first intercom is described in detail in the foregoing embodiments, and for brevity of description, details are not repeated here.
As an example, the second intercom includes any of the following:
Interphone except the first interphone in the first communication cluster;
an intercom that is in the same communication channel as the first intercom.
As an example, the server may store the correspondence between the communication clusters and the interphones in advance, and at this time, determining the interphone except the first interphone in the first communication cluster as the second interphone may be adopted. The server may not store the correspondence between the communication clusters and the interphones, and in this case, the interphone that is in the same communication channel as the first interphone may be determined as the second interphone.
As an example, since the interphones perform the division of the communication clusters in advance, the interphones of the same communication cluster have the same quantum session key set, whereas the interphones of different communication clusters do not have the same quantum session key, so that only the interphones predefined as the same communication cluster can perform communication. That is, in the process of forwarding communication data by using the server, the communication security of the same communication cluster can be ensured.
In some embodiments, one communication cluster corresponds to one transmission channel, and the determining the second interphone based on the first transmission channel used by the first interphone to send the first transmission data in step 201 may specifically include:
if the transmission channel corresponding to the first communication cluster is the first transmission channel, the interphone which is except the first interphone and is currently located in the first transmission channel can be determined to be the second interphone.
As an example, if the transmission channel corresponding to the first communication cluster is the first transmission channel, the first intercom may be characterized as first transmission data sent by the first intercom with the originally agreed transmission channel, and at this time, the intercom that is other than the first intercom and is currently in the first transmission channel may be determined as the second intercom.
As an example, this way, the server does not need to pay attention to which specific interphones are initially in the same communication cluster, and thus the efficiency of determining the second interphone can be improved, so that the first transmission data can be sent to the second interphone more efficiently.
In some embodiments, one communication cluster corresponds to one transmission channel, and the determining the second interphone based on the first transmission channel used by the first interphone to send the first transmission data in step 201 may specifically include:
And if the transmission channel corresponding to the first communication cluster is the first transmission channel, determining the interphone except the first interphone in the first communication cluster as the second interphone.
As an example, the service side is required to store the interphones corresponding to the communication clusters in advance, which brings the advantage that when a certain interphone in the first communication cluster is not set as the first transmission channel according to the preset convention, the first transmission data sent by the first interphone in the first communication cluster can be obtained.
In some embodiments, one communication cluster corresponds to one transmission channel, and the determining the second interphone based on the first transmission channel used by the first interphone to send the first transmission data in step 201 may specifically include:
If the transmission channel corresponding to the first communication cluster is the second transmission channel, determining whether the first transmission data comprises a predefined manager identification; and if the first transmission data does not comprise the manager identifier, determining the interphone except the first interphone in the first communication cluster as the second interphone.
Here, the manager identification is used to indicate that the interphone has cross-channel interaction rights.
As an example, a certain intercom may belong to a main intercom, which may communicate with each intercom, only the main intercom being divided into the first communication clusters in advance. Therefore, when the first transmission data includes the manager identifier, the first interphone may be represented as the master interphone, and correspondingly, when the first transmission data does not include the manager identifier, the first interphone may be represented as not the master interphone, only when the first interphone does not perform data transmission according to the predefined transmission channel, the server side may directly determine the interphones except the first interphone in the first communication cluster as the second interphone, so that the interphone originally determined as the first communication cluster may receive the information sent by the first interphone.
In some embodiments, the server includes a quantum session key set included in any interphone, and the method may further include determining an interphone that is other than the first interphone and is currently in the second transmission channel as the second interphone if the first transmission data includes the manager identifier;
and transmitting the first transmission data to the second interphone, comprising:
decrypting a first ciphertext in the first transmission data by using the first quantum session key to obtain first data;
determining a second quantum session key from a second quantum session set corresponding to the second transmission channel, and encrypting the first data by using the second quantum session key to obtain a second ciphertext;
replacing the first quantum session key identification and the first ciphertext in the first transmission data by using the second quantum session key identification and the second ciphertext;
And sending the updated first transmission data to the second interphone.
As an example, when the first transmission data includes the manager identifier, the first interphone may be represented as the master interphone, and at this time, the master interphone may be represented as the interphone that may need to send information with the interphones of other communication clusters.
As an example, the server may determine, according to the communication channel adopted by the master interphone, the second interphone to which the data needs to be sent.
As an example, since quantum session keys corresponding to different communication clusters are different, one communication cluster corresponds to one transmission channel, and thus, one transmission channel corresponds to one quantum session key, and quantum session keys corresponding to different transmission channels are different. For example, a first communication cluster corresponds to a first transmission channel, to a first set of quantum session keys, and a second communication cluster may correspond to a second transmission channel, to a second set of quantum session keys.
Therefore, when the first transmission data is directly sent to the second interphone in the second communication cluster, the second interphone cannot decrypt the first ciphertext information in the first transmission data.
The server may pre-store a quantum session key set included in each communication cluster, and when the server determines that the first interphone is a master interphone and needs to send information to a second interphone in a second communication cluster, the server may decrypt the first ciphertext to obtain first data, encrypt the first data with the second quantum session key to obtain second ciphertext, replace the first quantum session key identifier and the first ciphertext in the first transmission data with the second quantum session key identifier and the second ciphertext, and obtain updated first transmission data, so that the updated first transmission data is sent to the second interphone, and the second interphone may normally decrypt the second ciphertext information to obtain the first data.
Therefore, in the present disclosure, under normal conditions, the server does not need to decrypt the first ciphertext information in the first transmission data, and only when the first interphone is the main interphone and the transmission channel adopted by the first interphone is different from the transmission channel corresponding to the pre-allocated communication cluster, the first ciphertext in the first transmission data needs to be encrypted, and the second quantum session key (the quantum session key included by the receiver) is used for re-encrypting, so that not only is the security of cluster communication protected, but also the main interphone can separately send information to different clusters, and the applicability is improved.
That is, in a normal case, only the interphone of the same communication cluster can perform information interaction, but when a main interphone needs to call, the main interphone can call across the communication cluster, and only the quantum session key set corresponding to the pre-allocated communication cluster needs to be stored. That is, the method of the present disclosure greatly improves security between trunking communications and ensures applicability.
It should be understood that the encryption algorithm adopted in the encryption process of the present disclosure may be a hybrid algorithm, that is, a hybrid algorithm of a post quantum algorithm and a national encryption algorithm, or a hybrid algorithm of a post quantum algorithm and an international algorithm, which is helpful to make the difficulty of cracking ciphertext information obtained by encryption larger.

Of course, the specific post quantum cryptography algorithm may be defined according to the actual situation.
The hybrid algorithm based on the post quantum algorithm and the national cryptographic algorithm can be understood as integrating the post quantum key packaging algorithm on the basis of the national cryptographic algorithm to obtain the final session negotiation key. The mixing method can obviously reduce the potential risk, thereby having the capability of resisting key cracking by a quantum computer to a certain extent. In the double signature mode, after the message is signed by using the traditional public key cryptographic algorithm, the message (which can comprise the traditional cryptographic signature result) can be signed by using the post-quantum public key cryptographic algorithm, and the combination of the two signature results is output. Or the signature sequence is exchanged, the signature is carried out by a quantum public key cryptographic algorithm, and then the signature is carried out by a traditional public key cryptographic algorithm. And when the verification is performed, only if the two sections of signature results are verified successfully, the verification is considered to be successful. This approach ensures that even if one of the algorithms is broken, the other algorithm can still provide security.
Of course, the hybrid encryption mode of the hybrid algorithm based on the post quantum algorithm and the international algorithm, and the hybrid encryption mode of the hybrid algorithm based on the post quantum algorithm, the national encryption algorithm and the international algorithm can be similar to the hybrid encryption mode based on the post quantum algorithm and the national encryption algorithm, and for the sake of brevity of the description, the description is omitted here.
It should be understood that, due to development of quantum computing, when the conventional encryption means is used for encrypting data, the possibility of being cracked by a quantum computer is high, so in the disclosure, the ciphertext information after encryption can resist the cracking of the quantum computer by adopting a hybrid algorithm, and meanwhile, the cracking of a classical computer can also be resisted by adopting a national encryption algorithm.
Referring to fig. 3, fig. 3 can be understood as an interaction diagram of the interphone and the server, and as can be seen from fig. 3, the interphone does not directly communicate with each other, but forwards information through the server, so that the communication distance between the communication clusters can be increased, and the communication is more stable.
In some embodiments, one interphone may correspond to one secure digital memory card, which may be used to store the quantum session key set loaded by the key distribution terminal.
As an example, since the secure digital memory card can be inserted into the interphone, the quantum session key set is stored through the secure digital memory card, so that the key distribution terminal only needs to distribute the quantum session key to the secure memory card, and in the actual use process, only needs to insert the secure digital memory card into the corresponding interphone. This approach may make it more convenient for the interphone to obtain the quantum session key, and to update the quantum session key (e.g., by updating a secure digital memory card).
By way of example, secure digital memory cards may include, but are not limited to, memory cards, SIM cards, and the like.
Meanwhile, it is particularly emphasized that the quantum computer is a physical device for performing high-speed mathematical and logical operation, storing and processing quantum information according to the law of quantum mechanics. When a device processes and calculates quantum information and operates on a quantum algorithm, the device is a quantum computer. Quantum computers are a key technology under investigation because of their ability to handle mathematical problems more efficiently than ordinary computers, for example, to accelerate the time to crack RSA keys from hundreds of years to hours.
That is, with the development of quantum technology, the effect of the protection means in the existing communication process may not be ideal, that is, the protection means in the traditional communication process is difficult to resist the attack of the quantum computer, while in the present disclosure, when the interphone encrypts the data, the interphone uses the quantum session key and encrypts by using the hybrid encryption algorithm, so that the attack of the quantum computer can be resisted to a certain extent, and the security of the communication process is enhanced.
In some implementations, the hybrid encryption algorithm may also be pre-stored in the secure digital memory card.
In some implementations, the application scenario of the present disclosure may be applied to military drill scenarios, for example, where it may be required to face division into multiple teams, where information interaction may be possible between members of the same team, and information interaction may not be possible between members of different teams, and this need may be obviously satisfied by using the manner of the present disclosure.
