Embodiment one
As shown in Figure 1A, the embodiment of the present invention provides a kind of data processing method, below in conjunction with Figure of description, the specific embodiment of the present invention is described in detail:
Step 1A01, embedded controller EC, when power-up initializing, read driving file from default memory block and unzip in default memorizer;
In the embodiment of the present invention, the memory block that this specific memory block delimited when being compiling embedded controller firmware ECFW.
When implementing, EC engineer, when compiling ECFW, delimit memory block from ECFW, and be stored in these blocks by OptionROM file.
Step 1A02, described embedded controller EC send the first notification message to basic input-output system BIOS so that BIOS reads from described default memorizer according to described first notification message and performs described driving file.
Method provided by the invention will with the driving file (content that security of system is information-related, such as: OptionROM) it is prestored in default memory block, firmware (the Firmware of EC, it is called for short FW) only just can be modified through EC, even if so start to operating system aspect also can guarantee that the safety of information, so the safety that the present invention provides scheme is higher than prior art.
In order to notify that BIOS drives file to read and decompressed, then the method for the present invention after reading driving file and unzip in default memorizer from default memory block, may further comprise:
Described embedded controller EC arranges marker bit, and described marker bit is used for indicating described driving file and reads and decompressed so that described BIOS reads and perform described driving file according to described flag bit.
In order to ensure driving file not by other program malicious modification, in the scheme that the embodiment of the present invention provides after BIOS has performed driving file, data in memory block can also be set to unreadable not writeable, thus preventing from being modified, described embedded controller EC sends the first notification message to after BIOS, and the method also includes:
When receiving BIOS the second notification message returned, described default memory block is arranged unreadable not writeable by described embedded controller EC, and wherein, described second notification message is used for determining that BIOS has performed described driving file.
In order to know the scheme that the detailed description embodiment of the present invention provides, below in conjunction with concrete use environment, a kind of data processing method provided by the invention is further described, specifically includes:
One, described software-driven is the driving of fingerprint recognition (FingerPrint), then implementing of the inventive method may is that
Fingerprint recognition is the equipment for detecting and compare fingerprint, self needs a driving to work. In prior art, the driving of fingerprint recognition is left in BIOSFW. Time specifically used, when BIOS starts shooting, if being provided with startup password, BIOS then detects " fingerprint recognition " equipment, and then prompting user substitutes password by fingerprint typing. Fingerprint typing is also compared by rear, and BIOS then drives through " fingerprint recognition ", is saved in fingerprint equipment by startup password. BIOS password detects by rear, starting up's operating system; Because the safety of BIOSFW is not high, being vulnerable to Malware and destroy, so the driving file of " fingerprint recognition " left in BIOSFW, Hazard ratio that is destroyed or that distort is higher.
In data processing method provided by the invention, " fingerprint recognition " device drives file, will be stored in ECFW, the step that implements during application " fingerprint recognition " equipment includes:
First, " fingerprint recognition " is driven file to read in internal memory by EC, and then BIOS is by driving file that fingerprint equipment is written and read in internal memory, such as fingerprint typing and password comparison;
Then, after " fingerprint recognition " is driven file operation to complete by BIOS, notice EC deletes " fingerprint recognition " in internal memory and drives file, and the driving file in ECFW is written and read protection.
Finally, after continuing to launch into operating system, " fingerprint recognition " directly cannot be driven file to destroy and distort by Malware, and Information Security is high.
Two, described software-driven is the driving that computer follows the trail of (Computrace), then implementing of the inventive method may is that
Computer is followed the trail of and is referred to: when computer is stolen, with the computer of computer tracking function, user can be helped to navigate to the geographical position at stolen computer place. In prior art, the driving file of computer tracking function leaves in BIOSFW. Time specifically used, in BIOS start process, BIOS can remove to perform the driving file of " computer tracking " function; After driving file to be performed, meeting resident process in internal memory, to start shooting after operating system, this process can connect network server end; Then the position at stolen computer place is resolved by server; The driving file of " computer tracking " leaves in BIOSFW; After entering operating system, it is vulnerable to the destruction of Malware, causes that computer tracking function lost efficacy.
In data processing method provided by the invention, the driving file of " computer tracking ", will be stored in ECFW, the step that implements during application " computer tracking " equipment includes:
First, " computer tracking " is driven file to read in internal memory by EC, and then BIOS is by driving file deinitialization computer tracking function in internal memory.
Then, after " computer tracking " is driven file to perform by BIOS, notice EC deletes " the computer tracking " in internal memory and drives file, and the driving file in ECFW is written and read protection.
Continuing to start after operating system, " computer tracking " directly cannot be driven file to destroy and distort by Malware, and Information Security is high.
As it is shown in figure 1, before embodiment of the present invention step 1A01, also include the storage by driving file to the memory block preset, wherein, it is achieved drive the mode of file storage may is that
Step 101, embedded controller will drive file to be stored in the memory block preset, wherein, the memory block that described memory block delimited when being compiling embedded controller firmware ECFW;
If existing in BIOSROM by described driving file (such as OptionROM file), these OptionROM files are not carried out write-protect by BIOS self. BIOSROM can pass through the execution aspect of Host aspect or CPU by malicious modification, so there is potential safety hazard.
In the method that the embodiment of the present invention provides, driving file is placed in ECFW, because EC self has executive capability, it is possible to the instruction of processor (CentralProcessingUnit, CPU) aspect is intercepted; And FW can be carried out safeguard protection by EC, it is possible to FW is set to: the state such as readable, writeable, unreadable, not writeable.
So in this embodiment, in the memory block delimited when OptionROM file being stored into compiling embedded controller firmware ECFW so that memory block can be configured by later stage embedded controller.
Step 102, described default memory block is set to read-only by described embedded controller.
In embodiments of the present invention, EC stores the memory block of OptionROM and is set to read-only, and the FW of EC only just can be modified through EC, even if so starting to operating system aspect and also be able to be effectively protected data.
