Description
Technical field
The present invention relates to chip technology field, more particularly to a kind of system and method is updated to chip.
Background technology
The intelligent terminal of prior art on startup, be required for substantially its BIOS (Basic Input/
Output System, basic input/output) normal boot-strap could be realized after system start completion, if BIOS system goes out
Now collapse, intelligent terminal can not work.And illegal renewal is carried out to BIOS system and operated, it would be possible to cause intelligent end
End equipment can not normally start, or even can threaten the information security of intelligent terminal.
The content of the invention
In view of the foregoing, it is necessary to provide a kind of chip more new system, it needs could be to BIOS after mandate is obtained
Chip is updated.
An embodiment of the present invention provides a kind of chip more new system, for being updated to a BIOS chips, the core
Piece more new system includes receiving module and authentication module, and the receiving module is used to receive renewal request；The authentication module is used
In judge it is described renewal request whether is authorized, and judge it is described renewal ask authorized after, it is allowed to described
BIOS chips are updated operation.
Preferably, the authentication module is used for according to the input key information request of renewal request feedback one, and judges
Whether the key information received is consistent with preset-key, and is judging that the consistent rear confirmation renewal request is authorized.
Preferably, the authentication module is additionally operable to the preset-key differ in the key information for judging the reception
During cause, forbid being updated operation to the BIOS chips.
Preferably, the preset-key is stored in the ROM of the BIOS chips, and the authentication module is used to judge
After the renewal request is authorized, it is allowed to write operation is carried out to the ROM of the BIOS chips, to be carried out to the BIOS chips
Renewal.
Preferably, the ROM is SPI ROM.
Preferably, the authentication module is additionally operable to after judging that the renewal request is authorized, it is allowed to described pre-
If key is modified or deletion action.
The present invention also provides a kind of chip update method, for being updated to a BIOS chips, the chip renewal side
Method comprises the following steps：
Receive renewal request；
Judge whether the renewal request is authorized；And
If the renewal request is authorized, it is allowed to is updated operation to the BIOS chips.
Preferably, it is described to judge that the step of whether the renewal request obtains mandate includes：
According to the input key information request of renewal request feedback one, and judge the key information that receives whether with it is described pre-
If key agreement, and judging that the consistent rear confirmation renewal request is authorized.
Preferably, it is described to judge also to include after the step of whether the renewal request obtains mandate：
If the renewal request is not authorized, forbid being updated operation to the BIOS chips.
Preferably, if the renewal request obtains the step of authorizing and also included：If the renewal request is authorized,
Allow to modify to the preset-key or deletion action.
Compared with prior art, said chip renewal system and method, because needs could be to BIOS after mandate is obtained
Chip is updated operation, improves the security of system.

Fig. 2 is a flow chart of a better embodiment of chip update method of the present invention.
Main element symbol description
| Chip more new system | 100 |
| Receiving module | 10 |
| Authentication module | 20 |
Following embodiment will combine above-mentioned accompanying drawing and further illustrate the present invention.
Embodiment
Referring to Fig. 1, the better embodiment of the present invention provides a chip more new system 100, for a BIOS cores
Piece is updated.Chip more new system 100 includes a receiving module 10 and an authentication module 20.Receiving module 10 is used to receive more
New request, renewal request can come from the request instruction that operator sends.Authentication module 20 is used to judge that the renewal is asked
Whether acquisition mandate, and judge the renewal request authorized after, it is allowed to operation is updated to BIOS chips.In this reality
Apply in mode, chip more new system 100 can be arranged in BIOS chips, can also be independently of BIOS chips.
Authentication module 20 judges that the detailed process whether renewal request obtains mandate is：Authentication module 20 is used for basis should
The input key information request of renewal request feedback one, and whether the key information that judgement receives is consistent with preset-key, and
Judge to confirm that the renewal asks to be authorized after the key information that receives is consistent with preset-key.For example, operator is worked as
Send request renewal request instruction after, it will return one request operator input key information prompting, when operator again
After inputting key information, whether the key information that the judgement of authentication module 20 receives is consistent with preset-key, if unanimously, permitted
Perhaps operator is updated operation to BIOS chips.When the key information that authentication module 20 judges to receive differs with preset-key
During cause, quiescing person is updated operation to BIOS chips, so as to avoid unwarranted back street operators couple to realize
BIOS chips are updated operation, improve the security of BIOS chip runtimes.
In an embodiment of the present invention, preset-key can be stored together with BIOS file, can specifically be stored
In the ROM of BIOS chip internals.After authentication module 20 is obtained and authorized in the renewal request for judging to receive, it will allow to grasp
Author carries out write operation to the ROM of BIOS chips, so as to which the data for needing to update are write in BIOS chips, completes to BIOS
The renewal of chip.In the present embodiment, ROM is preferably that (Serial Peripheral Interface, serial peripheral connect SPI
Mouthful) ROM.BIOS chips are by receiving SMI (System Management Interrupt, system management interrupt) signal
Know that operator is updated in request to BIOS chips.
Key information is managed for convenience, authentication module 20 is additionally operable to judging that renewal request is authorized
Afterwards, it is allowed to the preset-key is modified or deletion action.For example, current operator inputs key information and verified
By rear, expression current operator is authorized, and current operator will be allowed to change key information, or deletes key information to solve
Except authorization verification process.
Referring to Fig. 2, provide a chip update method in the better embodiment of the present invention.This chip update method is used
It is updated in BIOS chips, this chip update method can also be used in the chip shown in Fig. 1 more in new system.
This chip update method comprises the following steps：
S201：Receive renewal request.
S202：Judge whether renewal request is authorized.
S203：If renewal request is authorized, it is allowed to is updated operation to BIOS chips.
In step S202, specifically judge whether renewal request obtains mandate and can be：Ask to feed back according to the renewal
One input key information request, and whether the key information that judgement receives is consistent with preset-key, and after judging unanimously really
Recognize renewal request to be authorized.
This chip update method also includes step S204：If renewal request is not authorized, forbid to the BIOS cores
Piece is updated operation.Specifically, when the key information of reception is inconsistent with preset-key, that is, represent that renewal request does not obtain
It must authorize.Wherein, step S203 and step S204 are performed side by side.
This chip update method also includes step S205：If renewal request is authorized, it is allowed to the preset-key
Modify or deletion action.Wherein, step S204 and step S205 is also to perform side by side.
Said chip updates system and method, due to needing that behaviour could be updated to BIOS chips after mandate is obtained
Make, improve the security of system.
It will be apparent to those skilled in the art that the reality of production can be combined according to the scheme of the invention of the present invention and inventive concept
Border needs to make other to be altered or modified accordingly, and these change and adjustment should all belong to scope disclosed in this invention.
