Description

Information processing method and device

Technical Field

The present application relates to the field of computer technologies, and in particular, to an information processing method and apparatus.

Background

Currently, the client of the iOS (apple operating system) includes multiple versions, for example, a development version, an enterprise version, a TestFlight (grayscale) version, an App Store version, and the like, wherein the clients of the TestFlight (grayscale) version and the App Store version can be directly installed on the App Store of the iOS for downloading by users, that is, the clients of the TestFlight (grayscale) version and the App Store version are clients from official channels.

The background server corresponding to the client can provide multiple functions for the client, and in order to improve the data security, some specific functions are only opened to clients (clients of a TestFlight version and an App Store version) of official channel sources, but not to clients of unofficial channel sources.

Therefore, before the client side can enjoy the specific functions, it is required to check whether the channel source of the client side is the official channel source, and the client side can enjoy the specific functions only when the channel source of the client side is the official channel source.

In one approach, it may be verified by the mobileprovision file whether the channel source of the client is an official channel source.

The mobileprovision file may be a description file of signature information of the client, and in a general case, the mobileprovision file exists in the client of an unofficial channel source such as a development version client and an enterprise version client, and the mobileprovision file does not exist in the client of an official channel source such as a TestFlight version client and an App Store version client.

Thus, a system standard API may be used to call the query function to query whether a mobile provision file exists in the client through the query function, determine that the channel source of the client is an unofficial channel source when the result returned by the query function indicates that the mobile provision file exists in the client, and determine that the channel source of the client is an official channel source when the result returned by the query function indicates that the mobile provision file does not exist in the client.

However, the inventor finds that a lawbreaker can load a hook function on a client from an unofficial channel source and then modify a query result returned by the query function using the hook function so that the query result indicates that no mobileprovision file exists in the client, and thus, the channel source of the client from the unofficial channel source is determined as the official channel source by mistake, and then the client from the unofficial channel source can still enjoy a specific function of the background server, thereby reducing the security of data.

after the client development is completed, the client may be launched to a server corresponding to each operating system, for example, a server corresponding to an android operating system and a server corresponding to an IOS operating system, where the server corresponding to the operating system may encrypt a function instruction of the client in an image file in the client using a specific encryption algorithm to obtain an encrypted function instruction, and then replace an unencrypted function instruction of the client in the image file with the encrypted function instruction, and determine a loading instruction of a preset encryption type in a loading instruction set included in the image file, and then update encryption identification information in an encryption field of the loading instruction of the preset encryption type, for example, replace encryption identification information in the encryption field used for indicating that the function instruction of the client in the image file is encrypted with encryption identification information used for indicating that the function instruction of the client in the image file is not encrypted.

Then, the server can upload the client from the official channel of the server, so that the client can be downloaded and used by a large number of users.

After a user downloads and installs a client using an electronic device (having an operating system, such as an android operating system or an IOS operating system, etc.), the user can run the client on the electronic device to enjoy the functions of the client.

When the client is operated on the electronic device, the client can load the image file into a memory of the electronic device, and under the condition that the function of the client needs to be realized, a load instruction of a preset encryption type can be determined in a load instruction set included in the image file, encryption identification information in an encryption field of the load instruction of the preset encryption type is obtained, the encryption identification information can be obtained and used for indicating that the function instruction of the client in the image file is encrypted, then the encrypted function instruction of the client in the image file is decrypted by using a decryption algorithm corresponding to a specific encryption algorithm, an original (unencrypted) function instruction is obtained, and then the function of the client is realized based on the original function instruction.

In general, a function instruction of a client in an image file in a client (a client from an unofficial channel) that is not issued by a background server of an operating system is not encrypted, and in a load instruction of a preset encryption type in a load instruction set in the image file, encryption identification information in an encryption field is used to indicate that the function instruction of the client in the image file is not encrypted.

In view of this, in the present application, when the memory of the electronic device loads the image file of the client, a first starting address of the image file of the client in the memory is obtained, where the image file of the client at least includes a loading instruction set of the client. And searching a loading instruction with a preset encryption type in a loading instruction set included in the image file of the client according to the first starting address.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a flowchart illustrating steps of an information processing method according to the present application is shown, where the method is applied to an electronic device, and the method may specifically include the following steps:

in step S101, under the condition that the memory of the electronic device loads the image file of the client, a first start address of the image file of the client in the memory is obtained, where the image file of the client at least includes a loading instruction set of the client.

In the application, when a user needs to start a client on an electronic device, a start operation for starting the client may be input on the electronic device, and the electronic device may start the client after receiving the start operation, for example, the electronic device may load an image file of the client in a memory of the electronic device.

In addition, the electronic device may further record an address field (including a start address, an end address, and the like) of the image file in the memory, and may form a corresponding entry from the client identifier of the client and the address field of the image file of the client in the memory, and store the corresponding entry in the corresponding relationship between the client identifier and the address field. Wherein the client identifications of different clients are different.

Thus, in this step, when the first start address of the image file of the client in the memory is obtained, the identifier of the client may be obtained, then the address segment corresponding to the client identifier of the client is searched in the correspondence between the client identifier and the address segment, and then the minimum address in the address segment is obtained and used as the first start address of the image file in the memory.

In step S102, a load instruction of a preset encryption type is searched in a load instruction set included in the image file of the client according to the first start address.

In an embodiment of the present application, the image file of the client further includes a header file. Wherein, this step can be realized through the following process, including:

1021. and acquiring the space occupied by the header file in the mirror image file of the client.

In this application, the image file of the client includes at least a header file and a loading instruction set, and the location of the header file in the image file is adjacent to the location of the loading instruction set in the image file, and the location of the header file in the image file is located before the location of the loading instruction set in the image file.

In addition, in the data structure of the image file of the client, the size of the space occupied by the header file is often fixed, and may be, for example, one value of 30 bytes to 40 bytes. The occupied space size of the header file can be fixedly stored in a specific storage space of the electronic device in advance,

in this way, in this step, the size of the space stored in the specific storage space can be obtained and used as the size of the space occupied by the header file in the image file of the client.

1022. And acquiring a second initial address of a loading instruction set in the mirror image file of the client in the memory according to the first initial address of the mirror image file of the client in the memory and the space occupied by the header file in the mirror image file of the client.

Thus, when the mirror image file of the client is loaded in the memory of the electronic device, the address field of the header file in the mirror image file in the memory is adjacent to the address field of the loading instruction set in the mirror image file in the memory, and the address field of the header file in the mirror image file in the memory is located before the address field of the loading instruction set in the mirror image file in the memory.

The length of the address field of the header file in the mirror image file in the memory is the size of the space occupied by the header file in the mirror image file.

Therefore, in order to determine the second start address of the loading instruction set of the image file in the memory, the sum of the first start address of the image file in the memory and the size of the space occupied by the header file in the image file may be calculated to obtain a memory address, and the memory address may be used as the second start address of the loading instruction set in the memory.

1023. And acquiring the number of the loading instructions which are recorded in the header file of the mirror image file and are included in the loading instruction set.

In this application, the header file of the image file further records the number of the load instructions included in the load instruction set in the image file, so that all the instructions in the load instruction set can be determined in the memory according to the number and the second start address of the load instruction set in the memory.

1024. And searching the loading instruction with the preset encryption type in the loading instruction set in the image file of the client according to the number and the second initial address of the loading instruction set in the memory.

For example, in one approach, the load instructions are traversed from the second memory address in the memory until the number of load instructions are traversed, and thus the traversed load instructions are all load instructions in the load instruction set in the image file of the client.

And then searching the traversed load instruction for a load instruction with a preset encryption type.

Each load instruction has a type field therein for indicating the type of the load instruction. The type field in the load instruction with the preset ENCRYPTION type stores a specific type identifier, such as LC _ ENCRYPTION _ INFO.

Therefore, the load instruction with the specific type identifier stored in the type field can be searched in the traversed load instruction and used as the load instruction with the preset encryption type. For example, a load instruction with the type field storing "LC _ ENCRYPTION _ INFO" is searched in the traversed load instruction, and is used as a load instruction with a preset ENCRYPTION type.

If the preset encryption type load instructions in the load instruction set are searched in the image file only according to the second starting address, but the number of the load instructions included in the load instruction set is not combined, the electronic device only knows that the load instructions are traversed from the second starting address of the memory, but does not know under what conditions, the traversal may be ended after the second starting address of the memory is traversed to the last address of the memory, and then the preset encryption type load instructions in the load instruction set are searched in all the traversed contents.

However, in a general situation, the load instruction in the load instruction set of the image file often occupies only a portion of the memory after the second start address of the slave memory, and does not occupy all the memory after the second start address of the slave memory, so that the traversed load instruction may have a load instruction that is not located in the load instruction set of the image file, so that the electronic device traverses contents that may not be traversed, and thus efficiency of searching for the load instruction of the preset encryption type in the load instruction set in the image file may be reduced.

Therefore, according to the number of the loading instructions and the second starting address included in the loading instruction set, the loading instructions of the preset encryption type in the loading instruction set are searched in the image file, and the traversal under what condition can be finished can be known according to the number of the loading instructions included in the loading instruction set, so that the situation that the second starting address of the memory is traversed to the last address of the memory all the time is avoided, the situation that the contents which can not be traversed are traversed can be avoided, and the efficiency of searching the loading instructions of the preset encryption type in the loading instruction set in the image file can be improved.

In step S103, determining an encryption field in the load instruction of the preset encryption type; the encryption field records encryption identification information for indicating whether to encrypt the function instruction of the client in the mirror image file.

In this application, the functional instructions include instructions for implementing business logic of the client, and the like.

In step S104, the encryption identification information in the encryption field is acquired.

In step S105, it is determined whether the encryption identification information is used to indicate encryption of a function instruction of the client in the image file of the client.

In an embodiment of the present application, in a case that the encryption identification information is first preset encryption identification information, it may be determined that the encryption identification information is used to indicate that the function instruction of the client in the mirror file has been encrypted, and the first preset encryption identification information may be "1" or the like.

In another embodiment of the present application, in a case that the encryption identification information is second preset encryption identification information, it may be determined that the encryption identification information is used for indicating that the function instruction of the client in the mirror file is not encrypted, and the second preset encryption identification information may be "0" or the like.

In the case where the encryption identification information is used to indicate that the function instruction of the client in the image file of the client is not encrypted, in step S106, it is determined that the channel source of the client is an unofficial channel source.

In the case where the encryption identification information is used to indicate that the function instruction of the client in the image file of the client has been encrypted, in step S107, it is determined that the channel source of the client is an official channel source.

After the client is developed, the client may be launched to a server corresponding to each operating system, for example, a server corresponding to an android operating system and a server corresponding to an IOS operating system, where the server corresponding to the operating system may encrypt a function instruction of the client in an image file in the client using a specific encryption algorithm to obtain an encrypted function instruction, and then replace an unencrypted function instruction of the client in the image file with the encrypted function instruction, and determine a load instruction of a preset encryption type in a load instruction set included in the image file, and then update encryption identification information in an encryption field of the load instruction of the preset encryption type, for example, use encryption identification information used for indicating that the function instruction of the client in the image file is encrypted, and replace encryption identification information used for indicating that the function instruction of the client in the image file is not encrypted in the encryption field.

When the client is operated on the electronic device, the client can load the image file into a memory of the electronic device, and under the condition that the function of the client needs to be realized, a loading instruction with a preset encryption type can be determined in a loading instruction set included in the image file, encryption identification information in an encryption field of the loading instruction with the preset encryption type is obtained, the encryption identification information can be obtained and used for indicating that the function instruction of the client in the image file is encrypted, then a decryption algorithm corresponding to a specific encryption algorithm is used for decrypting the encrypted function instruction of the client in the image file, an original (unencrypted) function instruction is obtained, and then the function of the client is realized based on the original function instruction.

In view of this, in the present application, when the memory of the electronic device loads the image file of the client, a first starting address of the image file of the client in the memory is obtained, where the image file of the client at least includes a loading instruction set of the client. And searching a loading instruction with a preset encryption type in a loading instruction set included in the image file of the client according to the first starting address. Determining an encryption field in a loading instruction of a preset encryption type; the encryption field records encryption identification information for indicating whether to encrypt the function instruction of the client in the mirror image file. And acquiring the encrypted identification information in the encrypted field. And judging whether the encryption identification information is used for indicating the encryption of the function instruction of the client in the image file of the client. And under the condition that the encryption identification information is used for indicating that the function instruction of the client in the image file of the client is not encrypted, determining that the channel source of the client is an unofficial channel source.

By the method and the device, a system standard API is not used for calling the query function, whether the mobile provision file exists in the client side can be queried without the query function, and the channel source of the client side can be determined without the result returned by the query function. Therefore, the method avoids the illegal means that a lawbreaker loads a hook function on a client from an unofficial channel source and then modifies a query result returned by the query function by using the hook function so that the query result indicates that no mobileprovision file exists in the client so as to modify the query result to bypass detection.

Therefore, the accuracy of detecting the channel source of the client can be improved through the method and the device, and the safety of data can be further improved, for example, lawless persons are prevented from illegally crawling the data of the server by using the client of the unofficial channel source.

In addition, the channel source detection method for the client is not easy to bypass detection by lawless persons.

For example, on the basis of the present application, in one case, if a lawbreaker is in a load instruction set included in an image file in a client from an unofficial channel, the encrypted identification information in the encrypted field in the load instruction of the preset encryption type is privately modified to: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted.

Through the scheme of the application, the client side of the lawless persons from the unofficial channel can be mistakenly judged as the client side of the official channel source, and the detection of the application can be escaped.

However, in practice, in the process that the client runs on the electronic device, the operating system of the electronic device detects, in the load instruction set included in the image file, that the encryption identification information in the encryption field in the load instruction of the preset encryption type is: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted, so that the function instruction of the client in the mirror image file is decrypted by using a decryption algorithm corresponding to a specific encryption algorithm.

However, since the function instruction of the client in the image file is not obtained by using the specific encryption algorithm for encryption, an error, such as a messy code output, may occur when the decryption algorithm corresponding to the specific encryption algorithm is used for decrypting the function instruction of the client in the image file, which may result in that the function instruction of the client cannot be run, and thus the function of the client cannot be realized.

In view of this, because "in the load instruction set included in the image file in the client from the unofficial channel, the encrypted identification information in the encrypted field in the load instruction of the preset encryption type is privately modified to be: the encrypted identification information "for indicating that the function instruction of the client in the mirror file has been encrypted" may result in "the function instruction of the client cannot be run, and thus the function of the client cannot be realized".

Therefore, in order to realize part of functions of the client from the unofficial channel, a lawbreaker usually does not "modify the encryption identification information in the encryption field in the load instruction of the preset encryption type privately into a load instruction set included in the image file in the client from the unofficial channel: encrypted identification information "indicating that the function instructions of the client in the mirror file have been encrypted, in which case the client that is the source of the unofficial channel can be detected in the manner of the present application.

Service end corresponding to operating system

On the basis of the application, under another condition, if a lawbreaker in a loading instruction set included in an image file in a client from an unofficial channel, privately modifying encryption identification information in an encryption field in a loading instruction with a preset encryption type into: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted. And the lawbreaker uses an encryption algorithm to encrypt the function instruction of the client in the image file in the client to obtain the encrypted function instruction, and then uses the encrypted function instruction to replace the unencrypted function instruction of the client in the image file.

Through the scheme of the application, the client side of the non-official channel source of the lawless person can be mistakenly judged as the client side of the official channel source, and the detection of the application can be escaped.

However, in practice, since the specific encryption algorithm of the operating system and the decryption algorithm corresponding to the specific encryption algorithm are kept secret, a lawless person can hardly steal the specific encryption algorithm of the operating system and the decryption algorithm corresponding to the specific encryption algorithm, and thus, even if the lawless person encrypts the function instruction of the client in the image file in the client, the encryption algorithm used is different from the specific encryption algorithm.

And in the process that the client runs on the electronic device, an operating system of the electronic device detects that the encryption identification information in the encryption field in the loading instruction of the preset encryption type is: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted, so that the encrypted function instruction of the client in the mirror image file can be decrypted by using a decryption algorithm corresponding to a specific encryption algorithm.

However, since the encrypted functional instruction of the client in the image file is not encrypted by using a specific encryption algorithm, for example, the specific encryption algorithm of the operating system is different from the encryption algorithm used by the lawbreaker, and the decryption algorithm corresponding to the specific encryption algorithm of the operating system is different from the decryption algorithm corresponding to the encryption algorithm used by the lawbreaker, the decryption of the "encrypted functional instruction encrypted by using the encryption algorithm" by using the decryption algorithm corresponding to the specific encryption algorithm may cause an error, for example, a messy code is output, which may result in that the functional instruction of the client cannot be run, and further, the function of the client cannot be realized.

In view of this, since "in the load instruction set included in the image file in the client from the unofficial channel, the encryption identification information in the encryption field in the load instruction of the preset encryption type is privately modified to be: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted. And a lawbreaker uses an encryption algorithm to encrypt the function instruction of the client in the image file in the client to obtain an encrypted function instruction, and then uses the encrypted function instruction to replace the unencrypted function instruction of the client in the image file, which can cause that the function instruction of the client cannot be operated, and further the function of the client cannot be realized.

Therefore, in order to realize part of functions of the client from the unofficial channel, a lawbreaker usually does not "modify the encryption identification information in the encryption field in the load instruction of the preset encryption type privately into a load instruction set included in the image file in the client from the unofficial channel: and the encryption identification information is used for indicating that the function instruction of the client in the mirror image file is encrypted. And a lawbreaker encrypts the function instruction of the client in the image file in the client by using an encryption algorithm to obtain an encrypted function instruction, and then replaces the unencrypted function instruction of the client in the image file by using the encrypted function instruction.

Further, in another embodiment of the application, in the case that the channel source of the client is an unofficial channel source, the usage right of at least part of the functions of the client may be closed. For example, the client may actively turn off some specific functions, so that the specific functions are disabled, and the specific functions cannot be triggered to be used on the client, and the specific functions may be functions that are specified on the client by a technician in the process of developing the client in advance, and specific functions may be determined according to actual situations, and are not described in detail herein.

In another embodiment of the present application, in a case that the channel source of the client is an unofficial channel source, the server may be reported with exception information, where the exception information is used to indicate that the channel source of the client is an unofficial channel source. The abnormal information may include a Media Access Control (MAC) Address of the electronic device where the client is located, an Internet Protocol (IP) Address of the electronic device, an Identity Document (ID) of a user logged in the client, current location information of the electronic device, log information of the client, and the like.
