Specific embodiment
To make those skilled in the art more fully understand the present invention, embodiments of the invention are carried out in detail with reference to the accompanying drawings
Describe in detail bright but not as a limitation of the invention.
Embodiment one
The intelligent terminals such as computer carry out safety guiding can be such that the intelligent terminals such as computer load by the operation of certification
System or hardware drive program etc., so as to prevent Malware from invading, prevent the phenomenons such as malicious sabotage to smart machine.This
A kind of method for realizing that intelligent terminal is guided safely of inventive embodiments can be such that intelligent terminal is protected while carrying out safety guiding
The security and convenience of whole operation process are demonstrate,proved, with reference to Fig. 1 and Fig. 2, the method includes：
The safety guiding key storage that will be randomly generated is in embedded controller 1.The mode for randomly generating generates safety
Guiding key can increase security when being guided especially into safety of whole secure boot process, and this guides safely key
Can be stored in embedded controller 1 with diversified forms such as the character strings of long number, and can be in this, as raw security number
According to carry out it is subsequent call or than peering, certain key can also be reset.
Safety guiding key is divided into multiple cipher key sections 5, and at least one cipher key sections 5 are stored in external safety means 2
In.Specifically, safety guiding key can be divided into by respective type (such as corresponding lattice according to the type of external safety means 2
Formula) multiple cipher key sections 5, the cipher key sections 5 of respective numbers can also be wherein stored according to the type of external safety means 2.Example
If external safety means 2 are the external safety means 2 of USB Type-C interface types, it can not store to have with normal operating and surpass
The safety guiding key of character string long, now can by this have overlength character string safety guiding key be divided into it is multiple have compared with
The cipher key sections 5 of short character strings, and only can call the storage of part of key section 5 with receiving in the external safety means 2.
When external safety means 2 are connected electrically on intelligent terminal, cipher key sections of the storage in external safety means 2 are obtained
5 corresponding information, and guide key to judge whether the information is correct according to safety, and the intelligent terminal is carried out safety when correct
Guiding.In one embodiment, when external safety means 2 are connected electrically on intelligent terminal, intelligent terminal will monitor external
The internal memory of safety means 2 contains cipher key sections 5, and sends acquisition request, and intelligent terminal obtains the corresponding information of the cipher key sections 5 therewith,
This information can include title, quantity, data form, the order of response, the data of cipher key sections 5 various features such as in itself.Intelligence
Terminal can guide key to be selected these information or judged one by one according to safety, when being judged as correct, intelligent terminal
Safe guiding will be carried out.
The step of randomly generating safety guiding key includes：Embedded controller 1 is notified, makes its random generation safety guiding
Key.Embedded controller 1 can be notified by application program 7, can also be sent out to embedded controller 1 by input units such as keyboards
Instruction is sent, makes the generation safety guiding key at random of embedded controller 1.In the present embodiment, safety guiding key is randomly generated
The step of include：Embedded controller 1 is notified by application program 7, makes its random generation safety guiding key.Application program 7

Embedded controller 1 be ready for cryptographic operation, the application of application program 7 causes that this method has good ease for use, side
User use, and embedded controller 1 will generate at random safety guiding key, while will generate safety guiding it is close
Key is stored.
In order to simplify step, system resource is saved, improve service efficiency, in one embodiment, judge storage external
The step whether corresponding information of the cipher key sections 5 in safety means 2 is correct includes：Key is guided to judge cipher key sections 5 according to safety
Data it is whether correct in itself, for example judge the length and content of key section 5, as whether the data for judging cipher key sections 5 are in itself
One has 5 character strings of character, and whether the string content is correct in itself；Except judge cipher key sections 5 data in itself
Whether correctly also need to judge whether putting in order for cipher key sections 5 be correct, for example, safety guiding key is divided into 10 cipher key sections
5, will wherein 5 cipher key sections 5 arrange in a certain order after store in external safety means 2, carried out when to external device
When 5 cipher key sections 5 stored to it during checking are verified, this 5 putting in order for cipher key sections 5 are verified, such as
Really this puts in order correctly, and the data of above-mentioned cipher key sections 5 are also correct in itself, then illustrate that the corresponding information of cipher key sections 5 is correct.
In one embodiment, when external safety means 2 of the external safety means 2 for USB Type-C interface types,
Include the step of the corresponding information of cipher key sections 5 of the storage in external safety means 2 is obtained：Grasped by embedded controller 1
The corresponding Vendor-specific message (Vendor Defined Messaging, VDM) of control USB Type-C interfaces reads key
Section 5.It should be noted that the external safety means 2 of USB Type-C interface types have multinomial key function, including power supply
(Power Delivery, PD) consults, cable detecting (Cable Detection, CD) and Vendor-specific message (Vendor
Defined Messaging, VDM), wherein Vendor-specific message (Vendor Defined Messaging, VDM) is allowed
