Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It is noted that related terms such as "first," "second," and the like may be used to describe various components, but these terms are not limiting of the components. These terms are only used to distinguish one element from another element. For example, a first component could be termed a second component, and, similarly, a second component could be termed a first component, without departing from the scope of the present invention. The term "and/or" refers to any one or more combinations of related items and descriptive items.
As shown in fig. 1 and fig. 2, fig. 1 is a flow diagram of a mobile terminal Keybox processing method based on an MTK platform according to the present invention; fig. 2 is a schematic block diagram of a Keybox processing method for a mobile terminal based on an MTK platform.
The invention discloses a method for processing a mobile terminal Keybox based on an MTK platform, which is characterized by comprising the following steps:
step S10, carrying out Keybox burning on the mobile terminal by using an MTKSNWriter, and writing a Keybox state mark into Nvram after the Keybox is successfully burnt by the mobile terminal in a Meta mode;
in step S10, MYK represents a concurrency department; MTKSNWriter means a tool used by the concurrency platform to write a number; keybox represents a keylocker function of an Android operating system for decrypting data and information of DRM-protected content; DRM represents digital rights management; nvram denotes a nonvolatile random access memory. The mobile terminal comprises mobile terminal equipment carrying an android system.
Step S20, restarting the mobile terminal, starting the Keybox_query service to read a Keybox State state value from nvram, and setting a system attribute value of the Keybox state;
in step S20, the keybox_query service represents a process for querying the Keybox state; the Keybox state flag is an operation return value fed back when the TEE system calls and writes a keybox function; the TEE systems include Google Trusty TEE, MTK trust TEE, microttrust TEE, and trust kernel TEE;
note that the system attribute value of the Keybox state indicates one system attribute of the Keybox installation state; specifically, the system attribute names are as follows: persist.key.keymaster_attest; value: true (keybox installed); false (keybox not installed); persist.key.done; value: true (keybox query operation completed); false (keybox state is being queried).
Step S30, after the mobile terminal enters the android system, performing system setting to display the installation state of the Keybox according to the system attribute value of the Keybox state; making system settings includes entering settings, then the system, then high-level and entering into the device. According to the method for processing the Keybox of the mobile terminal based on the MTK platform, disclosed by the invention, the processing is performed when the mobile terminal burns the Keybox, and the system attribute value of the Keybox state is set, so that the MTK platform Google Trusty TEE can detect and inquire the installation state of the Keybox on the mobile terminal.
Specifically, in step S10, a Keybox status flag is written into one Keybox state field in Nvram. After step S30 shown in fig. 1, the method further includes the steps of: step S40, when the ATA is used for testing the mobile terminal, the equipment side enters a factor mode, the keybox_query service starts to read the Keybox state value in the nvram and set the system attribute value of the Keybox state, when the ATA of the PC side sends a query Keybox specified instruction, the factor service of the equipment side receives the query Keybox specified instruction, reads the system attribute value of the Keybox state and feeds back the system attribute value to the ATA. The equipment end comprises a mobile terminal.
According to the method for processing the Keybox of the mobile terminal based on the MTK platform, google Trusty TEE is used for free, and the confirmation of the factory line and the client on the burning state of the Keybox is solved; saving 1RMB TEE OS License cost for each piece of PCB; the factory line PCB testing procedure is saved, and the addition of a station to independently verify the key box burning state is avoided. The principle is that by setting the system attribute value, the application layer, such as the MTK platform, can access the system attribute to identify and read whether the Ketbox is installed.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
