Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Secure storage areas is provided in mobile terminal applied by the embodiment of the present invention, as shown in Figure 1, secure storage areas is
The continuous memory space of physical address in mobile terminal internal storage, and secure storage areas is encrypted using public key.It is right
The process that the data of secure storage areas access are as follows: acquisition for mobile terminal data access request is taken in the data access request
The storage address for the data that band is requested access to；Mobile terminal judges whether the storage address belongs to secure storage areas, if belonging to,
The private key for obtaining user's input allows to access the secure storage after the public key successful matching for determining the private key and secure storage areas
The data saved in area.
In implementation, the public key of secure storage areas can be the centre that mobile terminal is written using fuse mode for mobile terminal
Device is managed, alternatively, the public key of secure storage areas is stored in winding protection subregion (the Replay Protect of the internal storage of terminal
Memory Block, RPMB) in.
Wherein, RPMB subregion can be used when needing to store significant data by user, which uses authorization encryption
Mechanism protect data.
The set-up mode of secure storage areas includes:
First, secure storage areas can be to be configured when leaving the factory in mobile terminal, and user is according to mobile terminal
Prompt determines whether to enable secure storage areas, if enabling secure storage areas, mobile terminal pops up the pairing of multiple groups public key and private key
Information prompts user to select one group from the unpaired message of the multiple groups public key and private key, and uses selected public key and private key
Unpaired message in public key be secure storage zone encryption.I.e. using fuse mode CPU is written in the public key of selection by mobile terminal
In or mobile terminal by the public key write-in internal storage RPMB in.Wherein, the data being written in a manner of fuse can not repair
Change, the data being written in the RPMB of internal storage can not also be modified.Public key once write-in if can not modify, only with the public key
The private key of pairing can pass through authentication.If not enabling secure storage areas, the secure storage areas configured can be used as common
Memory block uses.
Second, secure storage areas is also possible to mobile terminal and is carried out according to the instruction of user to the data field of internal storage
Division obtains.
Specifically, if mobile terminal is according to the residual capacity of data field, determination allows to divide data field, to data
Data field is divided into more than two subregions after the data progress data compression stored in area, wherein number is stored in data field
According to memory block be divided to the same subregion.Mobile terminal obtains multiple subregions according to division and modifies partition tables, and to dividing
To memory block in the subregions of not stored data be formatted rear mount to upper layer application.Mobile terminal according to it is specified or according to
User's instruction selects one divided in obtained multiple subregions not preserve the subregion of data as secure storage areas.
Specifically, mobile terminal modifies partition table according to obtained multiple subregions are divided, specifically: mobile terminal is in subregion
Increase in the subregion for dividing and obtaining in table, the corresponding partition table of each subregion in addition to the subregion for being stored with data in memory block
, the corresponding subregion in data field in partition table is modified according to the subregion for being stored with data in obtained subregion, in memory block is divided
List item, and modify the gauge outfit of partition table.Optionally, which is globally unique identifier's partition table (GUID Partition
Table, GPT；GUID, Globally Unique Identifier).
Wherein, big including at least the memory block of the location information of the subregion and the subregion in the corresponding subregion list item of subregion
It is small.Specifically, location information and the memory block that the subregion of data is stored in the subregion obtained according to division, in memory block are big
It is small, modify location information and memory block size in partition table in the corresponding subregion list item in data field.
Specifically, the quantity of intelligent terminal subregion list item according to included in the partition table after increase subregion list item, is repaired
Change the quantity of the subregion list item in partition table gauge outfit, and cyclic redundancy check code is carried out to the partition table after increase subregion list item
(Cyclic Redundancy Check, CRC) verification.
Behind any one configuration secure storage areas in both the above mode, include in data field in internal storage
Multiple subregions, the contrast schematic diagram being illustrated in figure 2 before and after data Division.
It should be noted that being required to safety certification and authorization to all operations of data in secure storage areas, therefore pacify
Data in full memory block will not be capped, and the data of secure storage areas will not lose after carrying out brush machine operation.
In order to solve the problems, such as not giving for change the data of storage after current mobile terminal is lost, provided in the embodiment of the present invention
