The execution main body of the embodiment of the invention is the android terminal, when a user needs to synchronize data on the iOS terminal to the android terminal, the android terminal can simulate the iCloud communication protocol on the android terminal, realize data communication between the android terminal and the iCloud server through the simulated iCloud communication protocol, realize that the android terminal directly obtains the data from the iCloud server, simplify the data synchronization process between the android terminal and the iOS terminal, and improve the data synchronization efficiency.
Before the data synchronization is carried out through the method provided by the embodiment of the invention, the android terminal firstly acquires the iCloud data packet, and simulates the iCloud communication protocol according to the acquired iCloud data packet. The iCloud data packet can be acquired from the iOS terminal by a technician, and then the acquired iCloud data packet is submitted to the android terminal. After receiving the iCloud data packet submitted by the technical personnel, the android terminal simulates the iCloud communication protocol in the following mode, including:
analyzing the iCloud data packet to obtain format information of the iCloud data packet; determining a communication instruction corresponding to the iCloud data packet by reverse pushing according to the format information of the iCloud data packet; sending the communication instruction to an iCloud server, and determining the communication instruction as the iCloud communication instruction if receiving an iCloud data packet returned by the iCloud server; if the iCloud data packet returned by the iCloud server is not received, returning to execute the communication instruction corresponding to the iCloud data packet determined by reverse pushing according to the format information; and generating the iCloud communication protocol according to all the determined iCloud communication instructions.
And reversely pushing the communication command corresponding to the iCloud data packet and then sending the communication command to the iCloud server. And if the communication instruction is correct, the iCloud server sends the iCloud data packet to the android terminal according to the communication instruction after receiving the communication instruction. If the communication instruction is incorrect, the iCloud server does not respond to the communication instruction after receiving the communication instruction, or returns instruction error indication information to the android terminal. In the embodiment of the invention, after the android terminal sends the reversely pushed communication instruction to the iCloud server, if the iCloud data packet returned by the iCloud server is received, the communication instruction is determined to be correct, and the communication instruction is added into the simulated iCloud communication protocol. If the iCloud data packet returned by the iCloud server is not received within the preset time length or the instruction error indication information returned by the iCloud server is received, the communication instruction is determined to be incorrect, the communication instruction is discarded, then the step of determining the communication instruction corresponding to the iCloud data packet by performing reverse push according to the format information of the iCloud data packet is returned, a new communication instruction is re-pushed in the reverse direction, and then the new communication instruction is sent to the iCloud server according to the mode. And if the preset number of communication instructions are continuously pushed backwards for the same iCloud data packet, and finally the preset number of communication instructions are determined to be incorrect, the iCloud data packet is abandoned.
In the embodiment of the invention, a large number of iCloud data packets are obtained from the iOS terminal, the communication instructions corresponding to the data packets are pushed backwards in the mode, and the communication instructions are sent to the iCloud server for error test, so that the correct communication instructions are determined to form the simulated iCloud communication protocol. The pre-simulated iCloud communication protocol can realize the following core functions: (1) obtaining an authorization token through the iCloud account and the password to authorize the subsequent request; (2) acquiring a list of file records; (3) acquiring record management logic data; (4) acquiring the attribute of a file record, wherein the attribute of the file record comprises file decryption information; (5) acquiring file downloading information corresponding to the file record; (6) key packet data is obtained.
As shown in fig. 1, after the iCloud communication protocol is simulated on the android terminal in the above manner, the data on the iOS terminal is synchronized to the local of the android terminal through the following operations of steps 101 and 102.
Step 101: and when the synchronous instruction is detected, acquiring file downloading information and recording management logic data corresponding to the iOS terminal identification through a pre-simulated iCloud communication protocol according to the iOS terminal identification carried by the synchronous instruction.
When a user needs to synchronize data on a certain iOS terminal to an android terminal, the user submits a synchronization instruction to the android terminal, and the synchronization instruction carries an iOS terminal identifier corresponding to the iOS terminal. And after detecting the synchronous instruction, the android terminal firstly displays a login page to the user. The user enters the user's iCloud account and password in the login page. And the android terminal acquires the iCloud account and the password of the user from the login page. And then, the iCloud account and the password are sent to the iCloud server through a pre-simulated iCloud communication protocol. And after the iCloud server receives the iCloud account and the password, acquiring a corresponding registration password according to the iCloud account, judging whether the registration secret is consistent with the received password, if so, returning an authorization token to the android terminal, and the android terminal receives the authorization token returned by the iCloud server. And if the password is inconsistent with the password, returning prompt information for prompting the password error to the android terminal. And the android terminal receives the iCloud account and the password input again by the user after receiving the prompt message, and acquires the authorization token from the iCloud server according to the mode.
After the authorization token is obtained in the above manner, the android terminal can perform data communication with the iCloud server through the pre-simulated iCloud communication protocol. And the android terminal sends the iOS terminal identification carried by the synchronous instruction to the iCloud server through a pre-simulated iCloud communication protocol.
The backup files of current iOS terminals are typically stored divided into a plurality of data blocks. The storage policy for the iCloud server is: the iCloud server only stores file download information of the backup file of the iOS terminal, which includes basic information of the file, file meta information, file download token (flag), and the like, and record management logic data. The file meta-information includes a key package, a file key, and the like. The record management logic data includes data mapping information including a mapping relationship between the file and the data block and a mapping relationship between the arrangement sequence number and the data block. The mapping relation between the files and the data blocks is used for indicating which data blocks a file comprises, the arrangement sequence number indicates the arrangement position of the data blocks when the file is formed, and a plurality of data blocks included in the file can be formed into the file again according to the arrangement sequence number. And the data blocks divided by the backup file of the iOS terminal are stored on the third-party cloud storage server in a distributed mode.
Since the user may have multiple iOS terminals at the same time, for each iOS terminal, the iCloud server stores file download information of the backup file of the iOS terminal, records the correspondence of the management logic data and the iOS terminal identification. And the third-party cloud storage server stores the corresponding relation between the plurality of data blocks corresponding to the iOS terminal and the iOS terminal identifier.
The iCloud server receives an iOS terminal identification sent by the android terminal, acquires corresponding file downloading information and record management logic data according to the iOS terminal identification, and then returns the acquired file downloading information and record management logic data to the android terminal. And the android terminal receives file downloading information and record management logic data corresponding to the iOS terminal identification returned by the iCloud server.
Step 102: and synchronizing the data of the iOS terminal corresponding to the iOS terminal identification to the local android terminal according to the file downloading information and the record management logic data.
And after the android terminal receives the file downloading information and the record management logic data returned by the iCloud server, downloading a plurality of data blocks corresponding to the iOS terminal identification from a third-party cloud storage server according to the file downloading information. Restoring the downloaded data blocks into an encrypted file according to data mapping information included in the record management logic data; analyzing a key package and a file key from file meta information included in the file downloading information; and decrypting the encrypted file according to the key package and the file secret key to obtain synchronous data.
The android terminal analyzes data mapping information from the record management logic data, the data mapping information comprises a mapping relation between the arrangement serial number and the data block, the arrangement serial number corresponding to each downloaded data block is determined according to the mapping relation, the data blocks are sequenced according to the sequence of the arrangement serial numbers according to the arrangement serial numbers corresponding to the data blocks, and the data blocks are combined into an encrypted file. And then, a key package and a file key are obtained from file meta information included in the file downloading information, the encrypted file is decrypted through the key package and the file key, and the obtained plaintext is data on the iOS terminal, so that the data on the iOS terminal is synchronized to the local of the android terminal.

The login module is used for receiving the iCloud account and the password input by the user. The data processing module is used for processing the synchronous data acquired by the function implementation layer in combination with the service requirements of the application, such as performing operations of removing duplicate or merging on the address list. The iCloud communication protocol module covers all protocols required for communication with the iCloud server, including all protocols required for communication processes such as authentication, backup information acquisition, file record information acquisition, file download information acquisition, record attribute acquisition, record management logic data acquisition and the like. The downloading module is used for acquiring file downloading information and recording management logic data through an iCloud communication protocol and downloading data blocks from a third-party cloud storage server, and the data blocks downloaded by the downloading module are a plurality of data blocks which are divided after being encrypted. The data decryption module is used for combining a plurality of data blocks downloaded by the download module according to the mapping relation according to the data mapping information included in the record management logic data, restoring the data blocks into an encrypted file, and decrypting the combined encrypted file by using the key package and the file secret key included in the file download information to obtain a plaintext file, wherein the plaintext file is the synchronous data.
