Description
Technical field
The present invention relates to a kind of protection system and method for electronic bits of data, particularly about a kind of electronic bits of data encryption system and method.
Background technology
Universal day by day along with electronic product, the capsule information of a lot of individuals, company or government be electronic digitalizing all, wherein has the data of secret character certainly.What these data were very frequent transmits in different media or storage, for example in Internet network or the storage medium.Therefore, the data of how carrying out is encrypted or peep-proof, prevents that those without authority from reading data content, has just become a very important problem.
In existing data encryption technology, major part all is to do data with cryptographic technique to encrypt, and therefore works as the user and wants to untie encrypted data, just must learn original setting code, for example this principle running of WinZIP software utilization.Yet this data encryption technology has individual shortcoming, is exactly that those without authority can repeatedly guess and password.That is to say,,, can guess easily in a short period of time password, and then crack encrypted data, thereby make encrypted data lose protection no matter use manually or computer software if Password Length is not enough or uncomplicated.
Summary of the invention
In view of above content, be necessary to provide a kind of electronic bits of data encryption system that confidential data is encrypted, can not be cracked easily even those without authority obtain this confidential data, thereby make confidential data obtain protection effectively.
In addition, also be necessary to provide a kind of electronic bits of data encryption method that confidential data is encrypted, can not be cracked easily, thereby make confidential data obtain protection effectively even those without authority obtain this confidential data.
A kind of electronic bits of data encryption system runs in the computing machine, and this computing machine comprises memory device and input equipment.Described electronic bits of data encryption system comprises: the data storage module is used for reading source book from memory device, and will be stored in the memory device through the encrypted data after encrypting; The key receiver module, be used to receive the user from the input equipment input be used for source book is carried out encrypted secret key; The data modular converter, being used for according to the ASCII character conversion mechanism is corresponding ASCII character with each character conversion of source book, and is corresponding ASCII character with each character conversion of key; The cryptographic calculation module, be used to produce a kind of algorithm, according to this algorithm the ASCII character of each character of source book and any one ASCII character of key are made cryptographic calculation and produced corresponding operation result, and operation result is converted to encrypted data according to the contrary conversion mechanism of ASCII character.
A kind of electronic bits of data encryption method is used for the source book that is stored in memory device is carried out encipherment protection, and this method comprises the steps: to read source book from described memory device; Receiving one group is used for source book is carried out encrypted secret key; Is corresponding ASCII character according to the ASCII character conversion mechanism with each character conversion in the source book; Is corresponding ASCII character according to the ASCII character conversion mechanism with each character conversion of key; Produce a kind of algorithm; According to this algorithm each character ASCII character of source book and any one ASCII character of key are made cryptographic calculation, and produce corresponding operation result; According to the contrary conversion mechanism of ASCII character operation result is converted to encrypted data; And the encrypted data that produces is stored in the memory device.
Compared to prior art; described electronic bits of data encryption system and method are because the key of user input is a character string arbitrarily; simultaneously to original confidential data and the computing of key process ASCII coding; tool is not in all senses for the resulting encrypted data; therefore even those without authority obtain encrypted data and can not be cracked easily; just do not have the risk of information leakage yet, thereby make original confidential data obtain protection effectively.
