Problems solved by technology
However, this kind of data encryption technology has a disadvantage, that is, the unauthorized person can guess the password many times.
That is to say, if the password length is not enough or not complex, whether it is using manual or computer software, the password can be easily guessed in a short period of time, and then the encrypted data can be cracked, so that the encrypted data loses its protection.

Embodiment Construction
[0013] Such as figure 1 Shown is a structure diagram of a preferred embodiment of the electronic data encryption system 10 of the present invention. In this embodiment, the electronic data encryption system 10 runs on a computer 1 , and the computer 1 includes a storage device 20 and an input device 30 . The storage device 20 is used to store original data and encrypted encrypted data. The original data can be text (TEXT) data, binary (Binary) data, or data in other formats, which are all composed of one or more characters, and each character is available on the storage device 20 Decimal numbers between 0 and 255. The input device 30 is used to input a group of keys for encrypting the original data, and the keys may be character strings of any combination of letters, numbers, or symbols. The electronic data encryption system 10 includes a data storage module 101 , a key receiving module 102 , a data conversion module 103 and an encryption operation module 104 .

The invention discloses system and method for enciphering electronic data. The method for enciphering the electronic data comprises the following steps of: reading original data; receiving a group of cipher keys for enciphering the original data; converting each character in the original data into a corresponding ASCII (American Standard Code for Information Interchange) code according to an ASCII code conversion mechanism; converting each character of the cipher key into the corresponding ASCII code according to the ASCII code conversion mechanism; generating an algorithm; carrying out encryption algorithm on each character ASCII code in the original data and any ASCII code of the cipher key according to the algorithm and generating a corresponding arithmetic result; converting the arithmetic result into enciphered data according to an ASCII code inverse conversion mechanism; and storing the generated enciphered data into storage equipment. By implementing the invention, confidentialdata can be enciphered and protected, and cannot be easily deciphered even if an unauthorized person wants to acquire the confidential data, thereby effectively protecting the confidential data.
Description
technical field [0001] The invention relates to an electronic data protection system and method, in particular to an electronic data encryption system and method. Background technique [0002] With the increasing popularity of electronic products, many important data of individuals, companies or governments have been electronically digitized, and of course the data are of a confidential nature. These materials are frequently transmitted or stored in different media, such as Internet networks or storage media. Therefore, how to do a good job of data encryption or anti-peeping to prevent unauthorized persons from reading the content of the data has become a very important issue. [0003] In the existing data encryption technology, most of them use password technology to encrypt data. Therefore, when users want to unlock encrypted data, they must know the original set password. For example, WinZIP software uses this principle to operate . However, this kind of data encryptio...
