Therefore, the AP participates in the encryption and decryption process of the voice data, so that the AP always works and cannot sleep, the power consumption of the terminal is greatly increased, and the cruising ability of the terminal battery is obviously reduced.
Example one
In order to solve the above technical problem, an embodiment of the present invention provides a voice data processing apparatus, fig. 2 is a schematic structural diagram of the voice data processing apparatus in the first embodiment of the present invention, and referring to fig. 2, the voice data processing apparatus 20 includes: a baseband processing module 201, an encryption/decryption interface module 202 and an encryption/decryption module 203;
here, the encryption/decryption module 203 is mounted to the baseband processing module 201 so that the baseband processing module 201 can directly access the encryption/decryption module 203 and perform data communication with the encryption/decryption module 203.
Then, the baseband processing module may write or clear data into the encryption/decryption module through the encryption/decryption interface module, for example, the baseband processing module may write a key into the encryption/decryption module, or may clear a key stored in the encryption/decryption module; the baseband processing module may also receive data from the encryption/decryption module, for example, the baseband processing module may receive voice data after encryption/decryption processing. Of course, the baseband processing module may also perform other data communication with the encryption/decryption module, and the embodiment of the present invention is not limited in particular here.
It should be noted that the baseband processing module, the encryption/decryption interface module, and the encryption/decryption module may be physically combined or separately arranged, and here, the embodiment of the present invention is not specifically limited.
In practical application, the baseband processing module and the encryption/decryption interface module can be combined into a baseband processor; the encryption/decryption module may be a built-in memory card integrated with a secure encryption chip, such as an SD card with an encryption function, a MicroSD (TF) card, or a Flash memory (Flash memory), or may be an external encryptor, which is plug-and-play, and of course, the encryption/decryption module may also be other components with an encryption/decryption processing function, and herein, embodiments of the present invention are not limited specifically.
Further, in order to enable the encryption/decryption module to be mounted on the baseband processing module, referring to fig. 3, the voice data processing apparatus 20 further includes: the encryption/decryption driver module 301.
Here, the encryption/decryption driver module is configured to suspend the encryption/decryption module to the baseband processing module, so as to establish a data communication channel between the baseband processing module and the encryption/decryption module.
In practical applications, when the encryption/decryption module is an SD Card integrated with a secure cryptographic chip, the encryption/decryption driver module may be an SD Card driver, as shown in fig. 4, the driver follows a standard MMC system architecture, and includes three parts, namely a Host (Host) driver 401, a Core (Core) driver 402, and an SD Card (Card) driver 403;

The following describes a voice data processing method according to an embodiment of the present invention with reference to the voice data processing apparatus in the above embodiment.
Then, fig. 5 is a schematic flow chart of a voice data processing method according to a first embodiment of the present invention, and referring to fig. 5, the voice data processing method includes:
s501: the baseband processing module receives the voice data to be processed from the upper-level processing module;
here, the voice data to be processed is voice data that needs to be encrypted or decrypted.
In the specific implementation process, the voice data processing apparatus needs to process the voice data, and firstly, the baseband processing module needs to acquire the voice data to be processed from the previous stage processing module.
In practical applications, the previous-stage processing module may be a modulation and demodulation module, or an encoding/decoding module, or may also be another processing module, where the embodiment of the present invention is not specifically limited herein. For example, when the previous processing module is a modem module, the voice data to be processed may be voice data obtained by demodulating a downlink voice signal from a communication network by the modem module; when the previous processing module is an encoding/decoding module, the to-be-processed speech data may also be speech data obtained by encoding speech or recording from an audio module by the encoding/decoding module.
S502: the baseband processing module calls an encryption/decryption interface module;
here, before sending data to the encryption/decryption module, the baseband processing module needs to call the encryption/decryption interface module, and then can perform data communication with the encryption/decryption module.
Specifically, after the baseband processing module obtains the to-be-processed voice data, the encryption/decryption interface module may be called to start to prepare for sending the to-be-processed voice data to the encryption/decryption module.
S503: the baseband processing module sends the voice data to be processed to the encryption/decryption module through the encryption/decryption interface module;
here, after the encryption/decryption interface module is called, the baseband processing module may send the voice data to be processed to the encryption/decryption module through the encryption/decryption interface module, so that the encryption/decryption module may perform corresponding processing.
S504: the encryption/decryption module processes the voice data to be processed by adopting a prestored secret key to obtain the processed voice data;
here, after the encryption/decryption module obtains the voice data to be processed, the encryption/decryption module performs corresponding processing on the voice data to be processed by using the key pre-stored in the encryption/decryption module, so that the processed voice data can be obtained.
Specifically, when the received voice data to be processed from the baseband processing module is the voice data to be encrypted, the pre-stored key is adopted to encrypt the voice data to be processed; or, when the received to-be-processed voice data from the baseband processing module is the voice data to be decrypted, the pre-stored key is adopted to decrypt the to-be-processed voice data.
It should be noted that the key pre-stored in the encryption/decryption module may be fixed, that is, all encryption/decryption processes use the same key, and at this time, the risk of being decrypted easily occurs; the pre-stored key in the encryption/decryption module may also be changed, that is, different keys are used for encryption/decryption in different situations, and in this case, the security is higher. In practical applications, if it is desired that the key pre-stored in the encryption/decryption module is changed, a manner of periodically changing may be adopted, such as periodically writing a new key into the encryption/decryption module every 3s, a manner of randomly changing may be adopted, such as writing a new key into the encryption/decryption module every random time, a manner of processing write-once may be adopted, such as writing a new key before each processing for use in the current processing, or writing a new key after each processing for use in the next processing. Meanwhile, the number of the keys pre-stored in the encryption/decryption module may be one, or may be multiple, such as two, three, and the like. The present invention is not limited to the embodiments described above, but may be embodied in various forms.
S505: the encryption/decryption module sends the processed voice data to the baseband processing module through the encryption/decryption interface module;
here, after the encryption/decryption module completes processing of the voice data to be processed, the encryption/decryption module sends the processed voice data to the baseband processing module through the encryption/decryption interface module.
S506: and the baseband processing module sends the processed voice data to the next-stage processing module.
Here, after receiving the processed voice data from the encryption/decryption module, the baseband processing module sends the processed voice data to the next processing module, so that the next processing module performs further processing.
In practical applications, the next-stage processing module may be a modulation and demodulation module, or an encoding/decoding module, or may also be another processing module, where the embodiment of the present invention is not specifically limited herein. Exemplarily, when the processed voice data is encrypted voice data, the next-stage processing module may be a modulation and demodulation module, and may be capable of modulating the decrypted voice data to obtain an uplink voice signal and sending the uplink voice signal to a communication network; when the processed voice data is the decrypted voice data, the previous-stage processing module may be an encoding/decoding module, and can decode the decrypted voice data and send the decoded voice data to the audio module for playing.
At this point, the processing of the voice data is completed. As can be seen from the above, in the technical solution provided in the embodiment of the present invention, the baseband processing module receives the to-be-processed voice data from the previous stage processing module, calls the encryption/decryption interface module, and sends the to-be-processed voice data to the encryption/decryption module through the encryption/decryption interface module; then, the encryption/decryption module processes the voice data to be processed by adopting a pre-stored secret key to obtain processed voice data, and sends the processed voice data to the baseband processing module through the encryption/decryption interface module; and finally, the baseband processing module sends the processed voice data to a next-stage processing module so as to carry out next-step processing. Therefore, when the voice data processing device is applied to the terminal, the baseband processing module can directly carry out data communication with the encryption/decryption module without a third-party processing module, such as participation of the application processing module, so that power consumption can be reduced, battery endurance can be improved, and good user experience is provided.
Example two
Based on the foregoing embodiments, in practical applications, in order to manage the key required in the encryption/decryption process, referring to fig. 6, the one or more voice data processing apparatuses 20 further include: a key management module 601.
Here, the key management module is configured to obtain a key and send the key to the baseband processing module. Then, after receiving the key, the baseband processing module can write the key into the encryption/decryption module through the encryption/decryption interface module, and further, the encryption/decryption module stores the key, so that after obtaining the voice data to be processed, the encryption/decryption module can perform encryption processing or decryption processing on the voice data to be processed by using the key.
Therefore, before the encryption/decryption module performs encryption processing or decryption processing on the voice data to be processed by using the key, the baseband processing module is further required to write the key required for encryption/decryption into the encryption/decryption module in advance.
Then, fig. 7 is a flowchart illustrating a voice data processing method according to a second embodiment of the present invention, and referring to fig. 7, before executing S504, the voice data processing method further includes:
s701: the key management module acquires a key and sends the key to the baseband processing module;
here, the key acquired by the key management module is the key stored in advance in the encryption/decryption module in step S504.
S702: the baseband processing module writes the key into the encryption/decryption module through the encryption/decryption interface module;
specifically, after receiving the key sent by the key management module, the baseband processing module calls the encryption/decryption interface module, and writes the key into the encryption/decryption module through the encryption/decryption interface module.
S703: the encryption/decryption module stores the key.
Specifically, after obtaining the key written by the baseband processing module, the encryption/decryption module stores the key in the encryption/decryption module for use in performing encryption/decryption processing on the voice data.
The following describes in detail the way of the key management module to obtain the key according to the difference of the key ways used by the encryption/decryption module.
Firstly, because the encryption/decryption module can process the voice data to be processed by adopting a mode of processing one key at a time, namely, the keys used by the encryption/decryption module for each processing are different, at this time, the key management module needs to process one time to obtain a new key.
In a specific implementation process, the key management module may obtain a key before each processing of the encryption/decryption module, and then let the baseband processor write in the encryption/decryption module, so that the encryption/decryption module can store a new key before each processing for use in the processing; alternatively, the key management module may obtain the key after each processing of the encryption/decryption module and then let the baseband processor write the key into the encryption/decryption module, so that the encryption/decryption module can store a new key after each processing for use in the next processing.
Secondly, because the encryption/decryption module can also process the voice data to be processed in a mode of processing one key for multiple times in a preset time period, namely, in the preset time period, the key used for each processing of the encryption/decryption module is the same, and at this time, the key management module needs to obtain a new key every other preset time period.
In practical applications, the key management module may obtain the key before the beginning of each predetermined time period, and then let the baseband processor write the key into the encryption/decryption module, so that the encryption/decryption module can store the key again before the beginning of each predetermined time period for use in the next predetermined time period. Here, the preset time period may be a fixed time period, such as 2 seconds, 5 seconds, etc., or may be a non-fixed time period, such as a random time. Specifically, when the preset time period is a fixed time period, such as 2 seconds, at this time, the key management module needs to obtain a new key every 2 seconds; or, when the preset time period is a non-fixed time period, such as a random time, the key management module may obtain a new key at random time intervals.
Exemplarily, a second embodiment of the present invention further provides a method for acquiring a key by a key management module, fig. 8 is a schematic flow chart of the method for acquiring a key in the second embodiment of the present invention, and referring to fig. 8, the method for acquiring a key includes:
s801: the baseband processing module receives a call encryption/decryption instruction;
here, the call encryption/decryption instruction is used to instruct encryption/decryption of the voice data to be processed from the upper-level processing module.
In practical applications, the call encryption/decryption instruction may be generated by a user operation, for example, the user selects to perform an encrypted call on an application interface, and then the application processing module generates a call encryption/decryption instruction and sends the call encryption/decryption instruction to the baseband processing module.
S802: the baseband processing module executes the conversation encryption/decryption instruction to generate a key request;
here, the baseband processing module, upon receiving the call encryption/decryption instruction, executes the call encryption/decryption instruction, thereby generating the key request. Specifically, the key request is used to instruct the key management module to obtain the key.
S803: the baseband processing module sends a key request to the key management module;
here, after generating the key request, the baseband processing module sends the key request to the key management module to request the key management module to obtain the key.
S804: the key management module responds to the key request, generates a key negotiation request and sends the key negotiation request to the network side;
here, the key agreement request is used to instruct the network side to issue the key.
Specifically, after receiving a key request from the baseband processing module, the key management module generates a key agreement request, sends the key agreement request to the network side, and requests the network side to issue a key.
S805: the key management module receives a key from the network side.
In practical application, after receiving a key agreement request from the key management module, the network side sends an agreement result to the key management module, and when the agreement result is successful, the network side also sends a key to the key management module. Further, the key management module receives the network side sent key.
The key management module finishes the process of obtaining the key, and after obtaining the key (performing S801-S805), the key management module may send the key to the baseband processing module (performing S701), so that the baseband processing module can write the key into the encryption/decryption module (performing S702), and finally, the encryption/decryption module stores the key (performing S703).
Further, after the encryption/decryption module performs encryption processing or decryption processing on the voice data to be processed by using the key, the baseband processing module may also clear the key stored in the encryption/decryption module in advance.
Then, fig. 9 is a flowchart illustrating a method for clearing a key according to a second embodiment of the present invention, and referring to fig. 9, the method for clearing a key may include:
s901: the baseband processing module generates a key clearing instruction after receiving the call end indication message;
specifically, the call end indication message may be generated by a user operation, for example, the user selects to end the call on the application interface, and then the application processing module generates a call end indication message and sends the call end indication message to the baseband processing module. Therefore, after receiving the call end instruction message, the baseband processing module generates a key clearing instruction for instructing itself to clear the key pre-stored in the encryption/decryption module.
S902: the baseband processing module executes the key clearing instruction and clears the key in the encryption/decryption module through the encryption/decryption interface.
Here, the baseband processing module executes the key clearing instruction after generating the key clearing instruction, and then clears the pre-stored key in the encryption/decryption module through the encryption/decryption interface module.
At this point, the baseband processing module completes the process of clearing the key.

Specifically, the baseband processor is configured to receive to-be-processed voice data from a previous-stage processing module, where the to-be-processed voice data is voice data that needs to be encrypted or decrypted; sending the voice data to be processed to a memory card through an encryption/decryption interface; the voice processing device is also used for receiving processed voice data from the memory card; sending the processed voice data to a next-level processing module; the memory card is used for receiving the voice data to be processed from the baseband processor; processing the voice data to be processed by adopting a prestored secret key to obtain processed voice data; and sending the processed voice data to the baseband processor through the memory card.
Furthermore, the memory card is also used for encrypting the voice data to be processed by adopting a secret key when the received voice data to be processed from the baseband processor is the voice data to be encrypted; or, when the received voice data to be processed from the baseband processor is the voice data to be decrypted, the key is adopted to decrypt the voice data to be processed.
