Configuration file after the addition authorization code only allows white list application program directly to access.
The technical program is to solve the sensitive configuration information of protection manufacturer, it is ensured that manufacturer oneself is served by energy
It is enough freely normally to read and guarantee that other software application read the attribute again.
The specific implementation step of the configuration information guard method of cloud cell phone manufacturer of the invention is described below in detail:
As described in Figure 2, which realizes that steps are as follows:
S1, the Added Business configuration file under system/system/etc/ catalogue, the business configuration file are that suffix is
The file of xml (extensible markup language), the business configuration file in the present embodiment are temporarily named into business.xml；
Then, it adds attribute if it is long character string type data according to xml reference format addition attribute configuration and matches
The format set is<string name="url">www.google.com</string>, for bool (logical type variable) class
Type data are worth if it is opening for true (true), otherwise are false (vacation), add the format of attribute configuration as <boolean
Name=" on " value=" true "/>, other types are customized.
In addition, the present embodiment adds also in the business configuration file and may have access to the application program of this file content (this is answered
White list application is referred to as with program), using application package name as mark.
S2, in the file system configuration file fs_config.c of Android source code add authorization code " 00400,
AID_SYSTEM, AID_SYSTEM, 0, " system/etc/business.xml " } ", the meaning of the authorization code of the present embodiment
It is ensuring that this document can only allow to possess the application program of system permission and directly access, other programs all do not have permission to access
Content therein.
S3, to need to provide BusinessService service (system business service) white to may have access to provide content
List application, BusinessService service pass through succession Binder (a kind of mode of Android striding course communication) class and will
It is entitled " business " that it is registered to ServiceManager (system service management) addition permission handle, then incites somebody to action
Business.xml content reads storage into memory.
After S4, the above preparation are completed, the system into customization is brushed again, application program can pass through the business
Handle takes the service object IBinder (an interface class of striding course communication) of registration from ServiceManager, white at this time
List application can access system business service by the IBinder object, and IBinder interface is called in white list application
Specified name information is passed in Parcel (small data packets) by transact function, and BusinessService will respond this
Request, BusinessService obtains uid belonging to this request process, and (CUSTOMER ID, each application program have uniquely
Identification code), then packet name is inquired by PackageManagerService (apply packet management service) by the uid, if
It is matched to the white list program that business.xml corresponds to name, then is returned to correct attribute value, otherwise mismatches and is ignored as
The request of this word.
In conclusion the present invention adds business configuration file in system image, suitable for any kind of data and not
Limit lengthy content, realize and carry out the validity judgement of application program by Binder mode, to it is some be not that manufacturer customizes
Application program is filtered processing to reach the detection for Malware.
