Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
The application first aspect provides a kind of method for detecting key, refer to Fig. 1, including：
S101：First IP hard disk of the server into the multiple IP hard disks sends detection instruction.
S102：The server receives multiple first Hash corresponding with the mark that the first IP hard disks are sent
Value.
S103：It is corresponding with the mark that other IP hard disks of the server in the multiple IP hard disks are sent

S104：When the target cryptographic Hash in the multiple second cryptographic Hash is not comprised in the multiple first cryptographic Hash
When, the server determines that the key corresponding with the target cryptographic Hash stored in the first IP hard disks is damaged.
For the technical scheme of the clear explanation embodiment of the present invention, one is carried out to storage system first and is introduced.Storage system
Including server and multiple IP hard disks, multiple IP hard disks are connected with server.IP hard disks provide store function, and be stored with key Key,
And the corresponding data Value of key.Server is managed to multiple IP hard disks, for example by user input storage system key and
Data are write in wherein one or more IP hard disks, or the key and data in IP hard disks are deleted according to user's request, repaiied
Change and update.The control of user and upper layer application to IP hard disks is managed, and is realized by server.
In the technical field belonging to the application, Key, referred to as key, also referred to as major key；Value is the corresponding value of key, simultaneously
Alternatively referred to as data, data content.In described below, key or Key refer to identical, value, and data and data content are referred both to
Value。
Specifically, within the storage system, a subregion includes multiple keys, and each key can be stored in multiple IP hard disks
In, such as 3, i.e., a complete key is stored in the 1st IP hard disk, the complete key of storage portion in 2 IP hard disks, the
Also a complete key is stored in 3 IP hard disks.And multiple IP hard disks that each key in same subregion is stored are
The multiple IP hard disks of identical.And can store the key of one or more subregions on an IP hard disk.
Safeguard there is a record sheet in storage system.Record has multiple IP hard disks corresponding to a subregion in record sheet.Lift
For example, IP address, index, port numbering that can be by recording IP hard disks in record sheet etc. record corresponding multiple IP
Hard disk.The application those skilled in the art can be selected according to actual needs, and the application is not particularly limited.
Therefore, before S101, to detect whether subregion to be detected is damaged in the key of the first IP hard-disc storages, inquiry note
Record table be assured that multiple IP hard disks corresponding with subregion to be detected specially which.And the first IP hard disks are that multiple IP are hard
One in disk.
In S101 detection instruction is sent to the first IP hard disks.Due to multiple subregions that may be stored with each IP hard disks
Key and data, so, in embodiments of the present invention, detection instruction includes the mark of subregion to be detected.According to mark, the first IP
Hard disk can determine multiple keys included by subregion to be detected.
Next, mark of the first IP hard disks in detection instruction, determines to be detected point from the cryptographic Hash of storage
Corresponding multiple first cryptographic Hash in area.Then multiple first cryptographic Hash are returned into server.And then in S102, server is received
Multiple first cryptographic Hash sent to the first IP hard disks.
Next, performing the corresponding with mark of other IP hard disks transmission of S103, i.e. server in multiple IP hard disks
Multiple second cryptographic Hash, judge whether that each second cryptographic Hash has the first equal cryptographic Hash.
Then, S104 is performed：When the target cryptographic Hash in the multiple second cryptographic Hash is not comprised in the multiple
During one cryptographic Hash, the server determines that the key corresponding with the target cryptographic Hash stored in the first IP hard disks is damaged
It is bad.
Specifically, either multiple first cryptographic Hash or multiple second cryptographic Hash, are all that IP hard disks pass through to storage
Key carries out what is obtained after Hash operation.Also, because each key stored on IP hard disks is different, therefore, carry out Hash
The cryptographic Hash obtained after computing is also just different.When the key in IP hard disks is not damaged, corresponding cryptographic Hash will be obtained；And work as IP
There is bad track in hard disk, and key just in this bad track when, then these keys being in bad track will be unable to read, and then also
Hash operation can not be carried out to the key of damage and obtain cryptographic Hash.
And multiple keys of the subregion to be detected stored in multiple IP hard disks are identicals, so, when multiple second cryptographic Hash
In target cryptographic Hash when being not comprised in multiple first cryptographic Hash, show the corresponding key of target cryptographic Hash in other IP hard disks
In it is normal, and be damaged in the first IP hard disks.
As an example it is assumed that subregion to be detected be subregion 1, correspondence 3 IP hard disks, respectively IP hard disks A, IP hard disks B and
IP disk Cs.Subregion 1 includes 10 keys, respectively Key1, Key2, Key3, Key4, Key5, Key6, Key7, Key8, Key9,
Key10.In S101, any one of server into IP hard disk A, IP hard disk B and IP disk Cs sends detection instruction, it is assumed that
It is IP hard disks A.Detection instruction includes the mark of subregion 1.IP hard disks A is received after detection instruction, according to the mark of subregion 1, will
Corresponding multiple first cryptographic Hash of multiple keys return to servers in subregion 1.For convenience of explanation, it is assumed that it is many that IP hard disks A is returned
Individual first cryptographic Hash is：
Hash_treeA_Key1 (10), hash_treeA_Key3 (53), hash_treeA_Key4 (24), hash_
TreeA_Key5 (1), hash_treeA_Key6 (36), hash_treeA_Key7 (12), hash_treeA_Key8 (2),
Hash_treeA_Key9 (52), hash_treeA_Key10 (3).
Simultaneously, it is assumed that IP hard disks B send multiple second cryptographic Hash be respectively：
Hash_treeB_Key1 (10), hash_treeB_Key2 (6), hash_treeB_Key3 (53), hash_
TreeB_Key4 (24), hash_treeB_Key5 (1), hash_treeB_Key6 (36), hash_treeB_Key7 (12),
Hash_treeB_Key8 (2), hash_treeB_Key9 (52), hash_treeB_Key10 (3).
IP disk Cs send multiple second cryptographic Hash be respectively：
Hash_treeC_Key1 (10), hash_treeC_Key2 (6), hash_treeC_Key3 (53), hash_
TreeC_Key4 (24), hash_treeC_Key5 (1), hash_treeC_Key7 (12), hash_treeC_Key8 (2),
Hash_treeC_Key9 (52), hash_treeC_Key10 (3).
Wherein, hash_treeA_Key1 (10) represents the first cryptographic Hash for the corresponding Key1 that IP hard disks A is returned, Key1's
Cryptographic Hash is specially 10.Other cryptographic Hash represent that meaning is similar, just no longer repeat one by one here.
Next, it is judged that whether each second cryptographic Hash has the first equal cryptographic Hash.First, IP hard disks B and IP
In multiple second cryptographic Hash that disk C is sent, target cryptographic Hash is defined as hash_treeB_Key1 (10) and hash_
TreeC_Key1 (10), in multiple first cryptographic Hash, hash_treeA_Key1 (10) and hash_treeB_Key1 (10) and
Hash_treeC_Key1 (10) is equal, so, Key1 is not damaged in the first IP hard disks.And in multiple first cryptographic Hash, mesh
When mark cryptographic Hash is hash_treeB_Key2 (6) and hash_treeC_Key2 (6), but in the absence of the first equal cryptographic Hash,
So determining that the Key2 stored in the first IP hard disks is damaged.Simultaneously, it can be seen that Key3, Key4, Key5, Key6, Key7,
Key8, Key9 and Key10 are included in multiple first cryptographic Hash in the first equal cryptographic Hash of corresponding multiple second cryptographic Hash
In, so above-mentioned 9 keys are not also damaged.
Same method, when IP disk Cs are as the first IP hard disks, that is, when judging whether to have key damage in IP disk Cs, also may be used
To determine that Key6 is damaged.Detailed process is just no longer repeated one by one here.
It can be seen from foregoing description in embodiments of the present invention, multiple second cryptographic Hash and multiple first Hash are passed through
Whether value is equal it may determine that whether the key in the first IP hard disks is damaged, it is no longer necessary to by all keys of network transmission
Hold, only transmit the cryptographic Hash that size of data is Kbyte grades.Therefore compared with prior art, detection efficiency is improved.
Further, after S104, in order to repair the key damaged in the first IP hard disks, in addition to：
The server sends the target cryptographic Hash to other described IP hard disks；
Receive the corresponding key of the target cryptographic Hash that other described IP hard disks are sent；
The key is sent to the first IP hard disks, so that key described in the first IP Hard Disk Repairs.
Specifically, after detecting that the corresponding key of target cryptographic Hash is damaged, the first IP of user's access is hard for convenience
The corresponding data of key are damaged in disk, in embodiments of the present invention, it will repair the key damaged.First, it is impaired in order to repair
Key, server sends target cryptographic Hash to other IP hard disks.During implementing, server can be only hard to other IP
An IP hard disk in disk sends target cryptographic Hash, can also be into every other IP hard disks, and the corresponding key of target cryptographic Hash is not
The IP hard disks of damage send target cryptographic Hash, and this application is not limited.
One or more of other IP hard disks are received after target cryptographic Hash, are closed according to the correspondence being stored in IP hard disks
System, determines the corresponding key of target cryptographic Hash, obtains the copy of key, is subsequently sent to server.Key is sent to by server again
In one IP hard disks, so that the key that IP Hard Disk Repairs are damaged.
Above-mentioned example is continued to use to illustrate.After it is determined that the Key2 in IP hard disks A is damaged, server is obtained from IP hard disks B
Key2 copy is taken, is subsequently sent in IP hard disks A.IP hard disks A stores Key2, so as to repair Key2.
The application second aspect provides a kind of method for generating cryptographic Hash, as shown in Fig. 2 including：
S201：Hash operation is carried out to each key in multiple keys, the corresponding cryptographic Hash of each key is obtained.
S202：The detection instruction that the reception server is sent.
S203：Multiple cryptographic Hash corresponding with the mark are sent to the server.
First, in embodiments of the present invention, multiple keys that the subregion to be detected that is stored with IP hard disks includes.In addition, also depositing
Contain the corresponding key of other subregions.In S201, IP hard disks carry out Hash operation to each key in multiple keys, obtain each key
Corresponding cryptographic Hash.Wherein, the process of Hash operation, principle and calculation with Hash operation in the prior art are carried out to each key
Method is similar, therefore just repeats no more here.
Because multiple keys are different, so, the cryptographic Hash of acquisition is also just different.Therefore, cryptographic Hash and sign
The key stored in IP hard disks is one-to-one.When the key in IP hard disks is not damaged, corresponding cryptographic Hash will be obtained；Work as IP
There is bad track in hard disk, and when having key just in this bad track, then these keys being in bad track will be unable to read, Jin Erye
Can not just Hash operation be carried out to the key of damage and obtain cryptographic Hash.
Certainly, carry out Hash operation except treating multiple keys that sense partitions include, IP hard disks can also to storage its
He carries out Hash operation by key, and then obtains the corresponding cryptographic Hash of other keys, and this application is not particularly limited.
In S202, the detection instruction that IP hard disks the reception server sends and come.Include to be detected point in detection instruction
The mark in area, according to the mark in detection instruction, IP hard disks can determine the targeted subregion of instruction to be detected, and be stored in

In one；
According to the corresponding relation and first cryptographic Hash, it is determined that with the first key corresponding to first cryptographic Hash；
First key is obtained, and first key is sent to the server.
Specifically, IP hard disks determine each key corresponding cryptographic Hash in multiple cryptographic Hash for convenience, and IP hard disks exist
Obtain after the corresponding cryptographic Hash of each key, further can preserve each key and the corresponding relation of cryptographic Hash.
The first key damage in other one or more IP hard disks is found when server, and the IP in the embodiment of the present invention is hard
When first key of disk is not damaged, IP hard disks are likely to be received the first cryptographic Hash of server transmission.IP hard disks are according to corresponding relation
