Description

A method of it key storage based on computer characteristic code and uses
Technical field
The present invention relates to application software system development field, especially a kind of key storage based on computer characteristic code and The method used.
Background technique
Under current network environment, information security accident emerges one after another, and information security system is to guarantee sensitivity in application system The key of information security.Most of application software systems all can protect user information safety using encryption and decryption mechanism.But it is No matter system requires key participate in encryption process using symmetrical or asymmetric encryption and decryption mode.Therefore, the guarantor of software systems Close property finally depends primarily on the safety of key, the safe keeping and the use of key is one on open computer network Very severe problem.
Existing common technique scheme includes:
1, in a program, key (plaintext) is directly programmed in program code for key hard coded, is made by the access of system constant Use key.
2, cipher key configuration is in system configuration file, by key (plaintext) configuration in system configuration file, program code Key is obtained by access system configuration file and is used.
3, key is saved in database, and key (plaintext) is saved in database, and program code passes through access data Library obtains key and uses.
4, encryption process is encapsulated into hardware by hardware enciphering and deciphering, and software is realized by the interface for calling hardware to provide Encryption and decryption functions.
Key is stored in code, configuration file or database by existing technical solution in the form of plaintext mostly. These technical solutions can not effectively prevent code decompiling, system personnel leakage configuration file, database from being dragged the situations such as library, nothing Method is really achieved the requirement of secure storage clear text key, and then directly affects system security.
Using hardware cipher mode, though it can effective lifting system confidentiality.But there is also at high cost, exploitation and using not There is a series of problems, such as compatibility in convenient, system.

Step S13: the computer characteristic code that step S12 is got is as the key of symmetric encipherment algorithm (AES), to key pipe The clear text key of reason person's input carries out symmetric cryptography, and is encoded using BASE64 to ciphertext, obtains ciphertext character string；
Step S14: the ciphertext character string after step S13 coding is saved as into local file, file designation enc.fn.
Further, in step S12, the calculation formula of computer characteristic code is as follows:
(MD5 (mainboard sequence number)+MD5 (CPU sequence number)+MD5 (hard disk serial number)+MD5 is (true for computer characteristic code=MD5 MAC Address of Network Card)+MD5 (current system user mark)).
Further, in step S13, the acquisition of the ciphertext character string uses following formula:
Ciphertext=BASE64_ENC (AES_ENC (computer characteristic code, the clear text key of Key manager's input)).
Further, the decrypting process specifically includes the following steps:
Step S21: decryption program entrance is injected into application software system starting by exploitation key decryption program (dynamic link library) In process (java agent can be used in java platform, and hook technology can be used in net platform)；
Step S22: key decryption program dynamic acquisition computer characteristic code；
Step S23: the enc.fn file under locally specified catalogue is read；
Step S24: the computer characteristic code that step S22 is got is as the key of symmetric encipherment algorithm (AES), to step The file content that S23 is read carries out BASE64 decoding and decrypts, and obtains clear text key；
Step S25: the clear text key that step S24 is got is arranged into the running environment of application software system；
Step S26: application software system can obtain key enforcement of going forward side by side by the running environment variable of access system and use.
Further, in step S22, the calculation formula of computer characteristic code is as follows:
(MD5 (mainboard sequence number)+MD5 (CPU sequence number)+MD5 (hard disk serial number)+MD5 is (true for computer characteristic code=MD5 MAC Address of Network Card)+MD5 (current system user mark)).
Further, in step S24, the acquisition of clear text key uses following formula:
Clear text key=AES_DEC (computer characteristic code, BASE64_DEC (enc.fn file content)).
Compared with prior art, the invention has the following beneficial effects:
1, not stored in clear key in application system of the invention, is obtained by technological means real time decrypting when the application system starts up To key and it is arranged into application process (only application system memory is visible), has utmostly ensured the risk that key is leaked.
2, key cryptograph files of the invention are associated with " one yard of a machine " with machine code, can not cryptograph files are stolen It is decrypted on other machines.
3, the present invention takes into account the problems such as use cost, exploitation convenience, system compatibility, is convenient for application and promotion.
