Abstract
The invention relates to a computer hardware encryption method, in particular to a computer hardware encryption method of encrypting data through combining hardware. The invention realizes the effect that the computer hardware encryption method is provided, through combining the hardware, a file is higher in safety after encrypted, and a user does not need to remember a password. The computer hardware encryption method has the advantages that by adopting the computer hardware encryption method of encrypting the data through combining the hardware, and utilizing a characteristic of dividing passwords in an RSA public key cryptosystem into an encryption key, that is to say, a public key, and a decryption key, that is to say, a secret key, the data to be encrypted is encrypted by utilizing the encryption key, and meanwhile, the enciphered data is decrypted by utilizing the decryption key in a USB flash disk. By adopting the technical scheme,a complicated password can be provided to increase safety, and the user does not need to remember the password.
Description
Technical field
The present invention relates to a kind of computer hardware encryption method, particularly relate to a kind of computer hardware encryption method data being encrypted by combined with hardware.
Background technology
Along with people more and more pay attention to computer security, in practice, the user of computer tends to the own sensitive information using to be encrypted.But when to file, row is encrypted, and generally all needs to arrange Crypted password, the memory of these passwords is become to the thing that makes a lot of user's headaches.Particularly user, forget Password while causing opening some vital documents, can cause very large trouble even to lose to user especially.
Summary of the invention
Technical problem to be solved by this invention is, a kind of computer hardware encryption method is provided, and it makes the fail safe after file encryption higher by the combination with hardware, and does not need to allow user remember the password of its setting.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of computer hardware encryption method, for combined with hardware, data are encrypted, and the method comprises the following steps:
The data of utilizing the encryption key in RSA public-key encryptosystem to be encrypted needs are encrypted;
When needs are decrypted encrypted data, from the USB flash disk connecting with computer, obtain the decruption key corresponding with above-mentioned encryption key enciphered data is decrypted;
The information of decrypted data is deposited in the deciphering journal file of external USB flash disk or local hard drive.
Advantage of the present invention is, the computer hardware encryption method that the present invention is encrypted data by combined with hardware, utilizing in RSA public-key encryptosystem password to be divided into encryption key is that public-key cryptography and decruption key are the feature of privacy key, the data of utilizing its encryption key to be encrypted needs are encrypted, and utilize the decruption key in u dish to be decrypted enciphered data simultaneously.After adopting technique scheme, very complicated password both can be set to promote fail safe, and not need again to allow user remember the password of its setting.
Accompanying drawing explanation
Fig. 1 is the main flow chart of the computer hardware encryption method that data is encrypted by combined with hardware of the present invention.
Embodiment
For further disclosing technical scheme of the present invention, be hereby described with reference to the accompanying drawings embodiments of the present invention:
Fig. 1 is the main flow chart of the computer hardware encryption method that data is encrypted by combined with hardware of the present invention, the computer hardware encryption method that combined with hardware is encrypted data passed through in figure can be used for combined with hardware data is encrypted, and the method comprises the following steps:
The data of utilizing the encryption key in RSA public-key encryptosystem to be encrypted needs are encrypted;
When needs are decrypted encrypted data, from the USB flash disk connecting with computer, obtain the decruption key corresponding with above-mentioned encryption key enciphered data is decrypted;
The information of decrypted data is deposited in the deciphering journal file of external USB flash disk or local hard drive.
The computer hardware encryption method that the present invention is encrypted data by combined with hardware, utilizing in RSA public-key encryptosystem password to be divided into encryption key is that public-key cryptography and decruption key are the feature of privacy key, utilizes the decruption key in USB flash disk to be decrypted enciphered data.Thereby very complicated password both can be set to promote fail safe, and not need again to allow user remember the password of its setting.
More than, by description of listed embodiment, the basic ideas and basic principles of the present invention have been set forth.But the present invention is never limited to above-mentioned listed execution mode, every equivalent variations of doing based on technical scheme of the present invention, improvement and deliberately become of inferior quality behavior, all should belong to protection scope of the present invention.
