A Method of Realizing File Access Control Through Timestamp and Encryption Algorithm

Abstract

A method for realizing file access control through time stamp and encryption algorithm, and a method for realizing file access control through the combination of time stamp and encryption algorithm, which can be run on multiple independent servers, and can adapt to the complexity of the Internet environment and cloud computing environment software and hardware equipment and a variety of development languages, does not rely on specific equipment or software, while the prior art relies on specific software tools or third-party security certification to achieve, compared with the prior art, the method of the present invention has a stronger compatibility. According to the actual needs of users, the access time of files can be flexibly set, and it can be flexibly allocated. It has the advantages of compactness and high efficiency, and can implement the method described in this invention under various environments of C / S and B / S. Traditional file access control systems cannot achieve such flexibility. And the time stamp is taken from an independent NTP server on the Internet, which has nothing to do with the time of the server or the user's computer. It can effectively protect sensitive data information and is difficult to crack.

Description

technical field [0001] The invention relates to the field of data security and protection of information technology, in particular to a method for realizing file access control through a time stamp and an encryption algorithm. Background technique [0002] At present, the methods for controlling user access to files in the Internet environment usually adopt access control methods such as controlling the login location, controlling the login account, permission verification or password verification and review. However, with the continuous development of technology and changes in people's working methods, the access requirements for sensitive files have also become diverse, such as requiring users to only query the contents of sensitive data files within a specified period of time, or only within a certain period of time Commit changes to data files within. [0003] Traditional file access control methods, in today's Internet environment, gradually expose the following proble...

Problems solved by technology

[0004] 1. The login control method through the virtual host in the local area network can effectively control the user's login location and indirectly achieve the goal of accessing a certain file during working hours, but it cannot meet the needs of users for mobile office

[0005] 2. Using the control method of password encryption algorithm can get rid of the limitation of fixed office, but it cannot solve the requirement of time-limited completion
