A Share-Oriented Security Folder Encryption System

Abstract

The invention relates to a safety file folder encryption system capable of achieving encrypted file sharing among multiple persons. The safety file folder encryption system comprises a safety file folder and a file operation processing program. The safety file folder is a file folder with a file directory and files included inside, the safety file folder is provided with a symmetric secret key which is also called a master secret key, each file in the file folder is encrypted by one randomly-symmetric secrete key, and the randomly-symmetric secrete keys are encrypted by the master secret key and then are stored in the safety file folder together with the encrypted files. The master secret key is encrypted by a public key which is shared by all the persons in the safety file folder and then stored in the safety file folder. Only the user who can decrypt the encrypted master secrete key can use the operated program to operate the files in the safety file folder through the file operation processing program, and manage the personnel sharing users in the safety file folder. According to the safety file folder encryption system, a group sharing strategy, an authorization server and an identification management system are introduced to enable group users to share the safety file folder.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a file encryption system, in particular to a secure folder encryption system capable of sharing encrypted files among multiple people. Background technique [0002] Carrying out security protection to the files stored on the computer is a problem that people are very concerned about, and carrying out security encryption to files is the most effective technical means to file security protection. For file encryption, a commonly used technical solution is to adopt a file encryption scheme called Safe Folder. The security folder itself is a kind of file, and it also has a file organization structure including files and file directories inside, which can be used to save multiple encrypted files, and organize the saved files through file directories. If we replace the file compression and decompression functions in the commonly used file compression program WinZip or WinRAR...
