The segmentation strategy may include the number of segmentation segments, segmentation points, segmentation length, and the like. In order to improve the security of the application software installation package, when the server divides different application software installation packages for different terminals through the division algorithm agreed with each terminal, different division strategies are adopted. For example, when different terminals request to download the same application software installation package, when the server divides the application software installation package for different terminals, the division strategies adopted are also different. Furthermore, when the server divides different application software installation packages for the same terminal, the division strategies adopted are also different.

After the division of the application software installation package is completed, the server adjusts the algorithm according to the preset order, acquires the order adjustment strategy according to the commodity information of the application software and the contract information of the terminal, etc., and adjusts the strategy according to the obtained order, and divides the The original sequence of the multiple installation package fragments is adjusted, wherein the sequence adjustment algorithm is a sequence adjustment algorithm pre-agreed with the terminal.

Preferably, the identification information of the terminal can be the subscription information of the terminal on the server side, such as the registration information of the terminal on the server side, mobile phone number, etc. The identification information of the application software is used to identify the application software to be downloaded. For example, when the application software to be downloaded is Tencent QQ, the installation package download request will encapsulate the identification information of Tencent QQ in the request and send it to the server.

After the server receives the installation package download request sent by the terminal, the server obtains the installation package of the corresponding application software according to the identification information of the application software. Optionally, before acquiring the application software installation package, the server may verify the identification information of the terminal carried in the installation package download request.

In order to improve the security of the application software installation package, when the server divides different application software installation packages for different terminals through the division algorithm agreed with each terminal, different division strategies are adopted. For example, when different terminals request to download the same application software installation package, when the server divides the application software installation package for different terminals, the division strategies adopted are also different. Furthermore, when the server divides different application software installation packages for the same terminal, the division strategies adopted are also different.

After the division of the application software installation package is completed, the server obtains the order adjustment strategy according to the preset sequence adjustment algorithm based on the product information of the application software and the terminal contract information, etc. The original order is adjusted. Wherein, the sequence adjustment algorithm is a sequence adjustment algorithm pre-agreed with the terminal.

In order to improve the security of the application software installation package, the server adopts different order adjustment strategies when adjusting the order of multiple installation package fragments through the order adjustment algorithm agreed with each terminal for different terminals. For example, when different terminals request to download the same application software installation package, and the server adjusts the sequence of the multiple divided installation package fragments for different terminals, the sequence adjustment strategies adopted are also different. Further, when the server adjusts the sequence of multiple installation package fragments that do not use the application software installation package for the same terminal, the sequence adjustment strategies adopted are also different.

The terminal can obtain the sequence adjustment strategy of the server according to the sequence adjustment algorithm pre-stored on the terminal and agreed with the server, and obtain the sequence adjustment strategy of the terminal according to the sequence adjustment strategy adopted by the server. Similarly, the server adopts different sequence adjustment strategies for different terminals, and correspondingly, different terminals adopt different sequence adjustment strategies when adjusting the sequence of multiple installation package fragments. Furthermore, when the same terminal adjusts the sequence of multiple installation package fragment packages that do not use application software, the sequence adjustment strategies adopted are also different. Specifically, since the installation package of the application software is the main running program of the application software, the recombined data package is the main running program of the application software.

In this embodiment, before the installation package of the application software is sent to the terminal, the server divides and reassembles the installation package, disrupts the order of the installation package fragments, and obtains the reorganized data packet. After receiving the reorganized data, the terminal After the package is packaged, the reassembled data package is reversely reassembled according to the preset algorithm to obtain the installation package of the application software. In this way, after the illegal terminal deciphers the encryption key and obtains the reassembled data package, the installation package of the application software cannot be easily obtained, which improves the security of the installation package of the application software and effectively prevents the problem of illegal installation of the application software.

Problem with installation.

FIG. 4 is a schematic structural diagram of a terminal provided by an embodiment of the present invention. As shown in FIG. 4 , the terminal includes: a receiving module 41 , a reassembly processing module 42 and an installation module 43 . Wherein, the receiving module 41 is used to receive the reassembled data packet sent by the server, the reassembled data packet is generated by recombining multiple installation package fragments, wherein the multiple installation package fragments are obtained by dividing the installation package of the application software. The reassembly processing module 42 is used to perform reverse reassembly processing on the reassembled data packet to obtain the installation package of the application software to be downloaded. The installation module 43 is used for installing the application software to be downloaded according to the installation package.

In this embodiment, the terminal further includes a sending module. When the terminal needs to obtain certain application software, the sending module sends an installation package download request to the server to instruct to download the application software installation package, so that the server can download the application software according to the The installation package download request sends a reassembled data package, wherein the installation package download request includes identification information of the terminal and identification information of the application software to be downloaded. The identification information of the terminal is used to identify the terminal that wants to obtain the application software. Preferably, the identification information of the terminal can be the subscription information of the terminal on the server side, such as the registration information of the terminal on the server side, mobile phone number, etc. The identification information of the application software is used to identify the application software to be downloaded. For example, when the application software to be downloaded is Tencent QQ, the installation package download request will encapsulate the identification information of Tencent QQ in the request and send it to the server.

After receiving the installation package download request sent by the terminal, the server obtains the installation package of the corresponding application software according to the identification information of the application software. Optionally, before acquiring the application software installation package, the server may verify the identification information of the installation package download request terminal. Specifically, the server verifies the identification information of the terminal in the installation package download request according to the identification information of the terminal pre-stored in the server. When the verification result is that the identification information of the terminal passes the verification of the server, the server can obtain the installation package of the corresponding application software according to the identification information of the application software. In this embodiment, the identity of the terminal sending the installation package download request is verified by the server to avoid illegal intrusion by illegal terminals, improve the security of application software, and reduce the risk of being acquired by illegal terminals.

After obtaining the installation package of the application software, the server uses the preset segmentation algorithm to obtain the segmentation strategy based on the product information of the application software and the contract information of the terminal, and divides the installation package according to the segmentation strategy into multiple installation package fragments. The segmentation strategy may include the number of segmentation segments, segmentation points, segmentation length, and the like. In order to improve the security of the application software installation package, when the server divides different application software installation packages for different terminals through the division algorithm agreed with each terminal, different division strategies are adopted. For example, when different terminals request to download the same application software installation package, when the server divides the application software installation package for different terminals, the division strategies adopted are also different. Furthermore, when the server divides different application software installation packages for the same terminal, the division strategies adopted are also different.

After the division of the application software installation package is completed, the server adjusts the algorithm according to the preset order, obtains the order adjustment strategy according to the commodity information of the application software and the contract information of the terminal, etc., and the server adjusts the strategy according to the order, and divides multiple installation package fragments The original sequence is adjusted, and then the server reassembles the sequence-adjusted multiple installation package fragments together to obtain a reassembled data packet, and sends the reassembled data packet to the receiving module 41 of the terminal. In order to improve the security of the application software installation package, the server adopts different order adjustment strategies when adjusting the order of multiple installation package fragments through the order adjustment algorithm agreed with each terminal for different terminals. For example, when different terminals request to download the same application software installation package, and the server adjusts the sequence of the multiple divided installation package fragments for different terminals, the sequence adjustment strategies adopted are also different. Furthermore, when the same terminal adjusts the sequence of multiple installation package fragments that do not use application software, the sequence adjustment strategies adopted are also different.

Optionally, after obtaining the reassembled data packet, the server may encrypt the reassembled data packet by using a first key to obtain the encrypted reassembled data packet, wherein the first key is randomly generated by the server. After the server encrypts the reassembled data packet, it encrypts the first key with the user public key pre-stored in the server to obtain the authorization file. The authorization file may also include commodity information of the application software, relevant information of the terminal, and the like. Correspondingly, an implementation structure of the receiving module 41 includes: a receiving unit 411 and a decryption unit 412 . Wherein, the receiving unit 411 receives the encrypted and reassembled data packet and the authorization file sent by the server, and sends the encrypted and reassembled data packet and the authorization file to the decryption unit 412, and the decryption unit 412 decrypts the authorization file according to the pre-stored user private key, The first key is obtained. After obtaining the first key, the decryption unit 412 decrypts the encrypted and reassembled data packet according to the first key to obtain the reassembled data packet of the application software to be downloaded. In this embodiment, before sending the reassembled data packet, the server encrypts the reassembled data packet, which can improve the security of the reassembled data packet, and further enhance the protection of the digital copyright of the application software.

After the receiving module 41 obtains the reassembled data packet, it sends the reassembled data packet to the reassembled processing module 42, and the reassembled processed module 42 performs reverse reassembled processing on the reassembled data packet to obtain the installation package of the application software to be downloaded. Optionally, an implementation structure of the reorganization processing module 42 includes: a segmentation unit 421 , an adjustment unit 422 and a combination unit 423 . The segmentation unit 421 adopts a segmentation algorithm pre-agreed with the server, obtains the contract information of the terminal and the product information of the application software, and obtains the segmentation strategy. The segmentation unit 421 segments the reassembled data packet according to the segmentation strategy to obtain multiple installation package fragments. Wherein, the segmentation strategy adopted by the segmentation unit 421 corresponds to the segmentation strategy adopted by the server. The segmentation strategy adopted by the segmentation unit 421 may include the number of segmentation segments, segmentation points, segmentation length, and the like. The server adopts different segmentation strategies for different terminals, and correspondingly, the segmentation units 421 of different terminals adopt different segmentation strategies in the process of segmenting the reassembled data packets. Furthermore, when the segmenting unit 421 of the same terminal segments the reassembled data packets of different application software, the segmenting strategies adopted are also different.

After the application software installation package division process is completed, the adjustment unit 422 adopts the order adjustment algorithm pre-agreed with the server, and obtains the order adjustment policy according to the contract information of the terminal and the commodity information of the application software. The adjustment unit 422 adjusts the sequence of the multiple installation package fragments according to the sequence adjustment policy, so as to obtain the original sequence of the multiple installation package fragments. The order adjustment policy adopted by the adjustment unit 422 corresponds to the order adjustment policy adopted by the server. Similarly, the server adopts different order adjustment strategies for different terminals, and correspondingly, when different terminals adjust the order of multiple installation package fragments, the order adjustment strategies adopted by the adjustment unit 422 are also different. Furthermore, when the adjustment unit 422 of the same terminal adjusts the sequence of multiple installation package fragments that do not use application software, the sequence adjustment strategies adopted are also different.

The combination unit 423 combines the sequence-adjusted multiple installation package slices to obtain the installation package of the application software to be downloaded. Specifically, since the installation package of the application software is the main running program of the application software, the recombined data package is the main running program of the application software. The segmentation unit 421 performs segmentation processing on the reorganized main running program to obtain N code segments, wherein N is an integer greater than or equal to 2, and the adjustment unit 422 adjusts the code segments of the N segments according to the obtained sequence adjustment strategy corresponding to the server. In order, the combination unit 423 recombines the N code segments after sequence adjustment to obtain the main running program of the application software, that is, the installation package of the application software to be downloaded.

The reassembly processing module 42 obtains the installation package of the application software to be downloaded after processing the reassembly data package, and the installation module 43 downloads and installs the application software to be downloaded according to the installation package.

In the terminal provided in this embodiment, the terminal receives a reassembled data packet, and the reassembled data packet is generated by recombining multiple installation package fragments, wherein the multiple installation package fragments are obtained by dividing the installation package of the application software. The recombined data package is divided, sequence adjusted and reassembled to obtain the installation package of the application software, and the application software is installed according to the installation package. In the prior art, after receiving the application software installation package and the authorization file, the terminal directly performs decryption processing, and then can obtain the application software installation package. In practical applications, once the application software installation package and authorization file are intercepted by illegal terminals during the transmission process, the encryption key used by the application software installation package and authorization file is relatively easy to decipher, so that illegal terminals can easily obtain the application software. The installation package makes the application software illegally copied and distributed offline, and the digital copyright of the application software has security risks. In the present invention, before the installation package of the application software is sent to the terminal, the installation package is divided and reorganized, and the order of the installation package fragments is disrupted, and the reorganized data packet is obtained. After the terminal receives the reorganized data packet, The installation package of the application software can only be obtained by performing reverse reassembly processing on the reassembled data packet according to the preset algorithm. In this way, the encryption key is deciphered at the illegal terminal, and the installation package of the application software cannot be easily obtained after obtaining the recombined data package, which improves the security of the installation package of the application software and effectively prevents the problem of illegal installation of the application software.
