Specific embodiment
The core of the application is to provide firmware safety detecting method, device and the computer-readable storage medium of a kind of hard disk
Matter evades the introducing and use to faulty hard disk, and then improve to efficiently identify out the security breaches of hard disk firmware in time
The security performance of storage system.
In order to which technical solutions in the embodiments of the present application is more clearly and completely described, below in conjunction with this Shen
Please attached drawing in embodiment, technical solutions in the embodiments of the present application is introduced.Obviously, described embodiment is only
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Referring to FIG. 1, Fig. 1 is a kind of flow chart of the firmware safety detecting method of hard disk provided herein, hard disk
Firmware file be stored in the Flash of hard disk, the firmware safety detecting method is applied to the CPU that connect with Flash, mainly
The following steps are included:
S11: the firmware file stored in Flash is read.
S12: the MD5 test value for generating firmware file is calculated.
S13: judge whether the MD5 standard value of MD5 test value and firmware file is consistent；If it is not, then entering S14.
S14: determine that hard disk does not pass through firmware safety test.
Specifically, the firmware safety detecting method of hard disk provided herein, has specifically included and has been directed to hard disk firmware
Integrity test.Hard disk producer can be attached to the MD5 standard value by firmware when issuing the firmware of hard disk simultaneously.
Wherein, MD5 (Message Digest Algorithm 5, Message Digest 5) be it is a kind of be widely used it is close
Code hash function can produce out a hashed value, that is, MD5 value (and can be described as digest value) for verifying.
After the content of hard disk firmware is distorted by hacker, by Message Digest 5 calculate generate MD5 value relative to
It can change before being tampered.It therefore, can be by CPU to the firmware read when the firmware to hard disk carries out security test
File carries out message digest computation, generates the MD5 value of the firmware file, and with MD5 standard value provided by hard disk manufacture manufacturer
It is compared, if the two is consistent, illustrates that the firmware file stored in Flash is completely, is not tampered with；And if the two
Difference then illustrates that the firmware file stored in Flash has been tampered with, and should not be thrown again there are security risk
Enter to use, to prevent bringing security threat to system.
As it can be seen that calculating hard disk using Message Digest 5 in the firmware safety detecting method of hard disk provided herein
The MD5 test value of firmware, and the MD5 standard value provided with supplier is compared, and obtains the integrity test knot of firmware file
Fruit evades in time using the hard disk and its firmware being tampered, ensures so as to which the safety problem of hard disk firmware is effectively detected out
Server system operates normally, and improves security performance.
Referring to FIG. 2, figure, 2 be the flow chart of the firmware safety detecting method of another hard disk provided herein.
As shown in Fig. 2, on the basis of the above, the firmware safety detecting method of hard disk provided herein is made
For a kind of preferred embodiment, S23 judge MD5 test value and firmware file MD5 standard value it is whether consistent after, further includes:
S24: if so, the digital signature of firmware file is decrypted using default decipherment algorithm.
S25: whether the signature value for judging that decryption generates is consistent with the former signature value of firmware file；If it is not, then sentencing into S28
Determine hard disk and does not pass through firmware safety test.
Specifically, in the firmware safety detecting method provided herein to hard disk, hard disk firmware can also be carried out
Validity test.
Generally, the manufacturer of hard disk usually can all be added to digital label when issuing new hard disk firmware wherein
Name.The default decipherment algorithm that the application can specifically be specified according to producer as a result, is decrypted digital signature to generate signature
Value, if the two is consistent, illustrates that the digital signature is correctly, to correspond to so that the former signature value with firmware file is compared
Hard disk firmware be legal；And if the two is inconsistent, illustrate the hard disk firmware not be from the manufacturer just
File is advised, there are huge security breaches, can determine that not by firmware safety test, and avoid coming into operation.
Wherein, as a kind of preferred embodiment, signature value includes the device id of hard disk.Certainly, signature value can also include
Some other important information, such as parameters, the those skilled in the art such as version number, amount of capacity of firmware file can voluntarily select
It selects and realization is set, the application is not limited thereto.
As shown in Fig. 2, on the basis of the above, the firmware safety detecting method of hard disk provided herein is made
For a kind of preferred embodiment, after judging whether signature value that decryption generates is consistent with the former signature value of firmware file in S25,
Further include:
S26: if so, judging whether the write operation executed to the Flash of hard disk succeeds；If so, determining into S28 hard
Disk does not pass through firmware safety test.
Specifically, the firmware safety detecting method of hard disk provided herein can further include to storage firmware
The Flash of file carries out write-protect test.
Generally, the firmware file of a component is stored in corresponding Flash, and component can be certainly in electrifying startup
The dynamic loading firmware file from Flash simultaneously runs starting.For the purpose of protection firmware file, when being written with firmware in Flash
After file, writing protection function will be generally opened, i.e., no longer user is allowed to carry out data write-in to Flash, to prevent firmware
File is tampered.The application can also attempt to that test data is written to the Flash for being stored with firmware file as a result, be with observation
It is no to be written successfully.
If being successfully written, illustrate that the Flash does not open writing protection function, then the firmware file of its storage is likely to sudden and violent
It has been exposed under the attack of hackers, has maliciously been stolen or distorted, there is biggish security risk.It can then sentence at this time
The fixed firmware file does not pass through safety test, avoids the come into operation hardware and its firmware file.
In addition, being judged after whether succeeding to the write operation that the Flash of hard disk is executed in S26, further includes:
S27: if it is not, then determining that hard disk passes through firmware safety test.
On the contrary, the Flash where illustrating the firmware file is to open writing protection function, therefore if write-in failure
Its safety has obtained certain guarantee.
After hard disk firmware has passed in succession through integrity test, validity test and Flash write-protect test, that is,
When the signature value and former signature value that MD5 test value is consistent with MD5 standard value, decryption generates are unanimously and Flash write operation fails, this
Field technical staff can determine that the hard disk has passed through firmware safety test.
It is worth noting that, those skilled in the art can also adjust the opposite of three kinds of tests according to the actual situation certainly
Sequentially, for example, it is also possible to carry out Flash write-protect test after integrity test completion, and it is completed in Flash write-protect
After carry out validity test；The application is not limited thereto.
Preferably, after determining that hard disk does not pass through firmware safety test in S28, further includes:
S29: corresponding security warning information is generated to prompt user.
It specifically, can be into one after the firmware file for determining hard disk is tampered, and hard disk is caused not pass through firmware safety test
Step generates corresponding information warning to warn user.Wherein, described information warning specifically can be with the side such as warning lamp, image
Formula shows that the application is not limited thereto.
