Wherein, the present invention proposes mainly for the problem of CDMA voice encryption, achieves a kind of general intelligent terminal voice encryption module, the module instance of flexible expansion AP can support the voice encryption of multiple BP.
Compared with common cdma android terminal, increase a road RPC passage newly, added the collection encryption function of key management functions and primary voice data.
Voice encryption of the present invention can only be bound with EVRC voice service, namely user can only do voice encryption in use EVRC voice service situation, system flow as shown in Figure 2, starting up of terminal initiates registration request to key server, after being registered to key server, set up new RPC path, for command and transfer of data.Concrete methods of realizing is: BP sets up a thread, and registration RPC process function, AP sets up node at linux kernel layer, is employed layer and calls.The data format of RPC transmission is TLV(tag-length-value) form, as follows: Tag, length, [tag, length, value, tag, length, value ... ]
First character joint is 0 be designated as transfer instruction, is 1 to be designated as transmission data.Afterwards immediately following the length of two bytes, the length of all data after mark, then start to be have tag respectively, length, value form whole datagram.
Check whether before caller initiating speech conversation and need voice encryption, if need voice encryption, usage data business initiates request cipher key service to key server, and key server returns encryption key after receiving request.The key received is saved in AP memory headroom by terminal encryption module, needed for encryption.
Between calling and called user, set up common EVRC voice conversation, business option is 0x3.
The collection doing speech data is needed after speech business is successfully established, primary voice data is obtained by increasing call back function in the interrupt function of ADSP, every 20 milliseconds of this call back function calls once, after getting primary voice data, user can be sent to AP preservation key by the RPC path set up is encrypted.The transmission time of RPC path is less than 2 milliseconds, the requirement of data processing within meeting 20 milliseconds completely.Data after encryption import ADSP into again by call back function, are sent to the terminal of the opposing party with the form of transparent transmission by network.After the terminal of the opposing party receives the data of eating dishes without rice or wine, be sent to AP by the RPC path set up and carry out Data Analysis, key-parsing according to cryptographic protocol and preservation goes out correct speech data, be sent to BP, send into ADSP to play back from audio path, need equally within 20 milliseconds, complete this operation.
In sum, by means of technique scheme of the present invention, transmitted and customize by voice initial data between application processor and baseband processor, encrypting module can produce Multi-instance simultaneously, each example for a BP service, can realize the encryption of multimode terminal.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
