Description
Technical field
The present invention relates to database encryption technology field, especially a kind of server high in the clouds diagnostic system rule base two level adds
Close, access method and system.
Background technology
Rule base have recorded the core knowledges such as fault diagnosis foundation, failure determination mode, failure rank, processing mode.Rule
Then storehouse uses sqlite3 database purchases, and system, which carries sqlite3 databases, does not have data base encryption function；But sqlite3
Provide data base encryption interface；Many is increased income encryption interface of the tissue based on sqlite3, have developed based on sqlite3's
Encrypting database；Open source software SQLCipher is exactly wherein to represent, and SQLCipher is based on OpenSSL and realized to sqlite3 numbers
Encrypted according to storehouse.SQLCipher databases provide C language interface and shell instruments.The shell tool operations that SQLCipher is provided
Input database key is needed before database, key is inputted with clear-text way；Shell instruments, which access, can cause database secret
Key leaks.
The content of the invention
It is an object of the invention to provide a kind of encryption of server high in the clouds diagnostic system rule base two level, access method and it is
System, effective safeguard rule storehouse data safety.
To achieve the above object, the present invention uses following technical proposals：
A kind of level encryption method of server high in the clouds diagnostic system rule base two, comprises the following steps：

Database access instrument input ciphertext key is called to realize to database access operation.
Further, clear text key in the reading configuration file, ciphertext key is generated using AES, including：Read
The clear text key in configuration file is taken, logic and operation is carried out to clear text key and self-defining character string, generates ciphertext key.
Further, the calling database access instrument input ciphertext key is realized to database access operation, including：
SQLCliper encryption interfaces are called, input ciphertext key, the access operation to rule base is realized in the case of key input is correct.
A kind of server high in the clouds diagnostic system rule base two level encryption system, including：Clear text key encrypting module, completion pair
Clear text key encryption generation ciphertext cipher key operation in configuration file；
AES package module, the encapsulation operation of clear text key AES is carried out to database access tool；
Key judge module, whether input ciphertext key is correctly judged.
Further, in addition to：Clear text key encrypts judge module, judges ciphertext key is encrypted as to clear text key whether
Success, return to judged result.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
A technical scheme in technical scheme has the following advantages that or beneficial effect：
The present invention provides a kind of server high in the clouds diagnostic system rule base two level encryption policy, to clear text key using encryption
Algorithm carries out secondary encryption generation ciphertext key, calls SQLCipher cipher key interfaces, key is inputted, to database after decryption
Operation, is effectively protected rule base data safety.

It is bright to be described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
As shown in figure 1, the level encryption method of server high in the clouds diagnostic system rule base two, reads in configuration file in plain text first
Key, the key of reading is encrypted；Ciphertext key adds as SQLCipher encryption keys to rule base after encryption
It is close.
As shown in Fig. 2 server high in the clouds diagnostic system rule base two level encrypted access method, data base tool are read first
Clear text key in configuration file, clear text key is encrypted, and generates ciphertext key；It is after the key success of generation ciphertext that ciphertext is close
Key after accessing successfully, returns to request results as rule base cipher key access rule base.
As shown in figure 3, reading the clear text key in configuration file, logical AND is carried out to clear text key and self-defining character string
Computing, ciphertext key is generated, successfully returns to 0, unsuccessfully return to -1.
As shown in figure 4, data base tool reads clear text key in configuration file first, clear text key is encrypted, it is raw
Into ciphertext key；Then SQLCipher cipher key interfaces are called, key are inputted, to database manipulation after decryption.
A kind of server high in the clouds diagnostic system rule base two level encryption system, including：Clear text key encrypting module, completion pair
