Abstract

The invention discloses a system and a method for encrypting and decrypting a file, which can solve the easy breaking problem of the encrypted file by adopting a technical means of completing encryption by storing part of the file in an encryption storage area in a USB storage device after splitting the file and completing decryption by restoring the file with the USB storage device used for encryption previously. Thus, the system and the method can improve the safety of the encrypted file.

Description

technical field [0001] The invention relates to a file encryption and decryption system and its method, in particular to a file encryption and decryption system and its method through a USB (Universal Serial Bus) storage device. Background technique [0002] With the rapid development of information technology and the advancement of the Internet, data digitization has become an indispensable part of life. Users use computers to store data electronically in various storage devices. Due to electronic data copying, transmission Easy and fast, in addition to convenience, it brings a lot of security considerations. In order to prevent others from illegally accessing data, copying, forging, stealing or destroying important data, there are many encryption and decryption software generated by encryption and decryption technology. produce. [0003] The general method of protecting electronic files and digital data, one is to directly encrypt the file, and use the encryption and decr...
