Cloud security management system of security electronic documents and method

Abstract

The invention discloses a cloud security management system and a method applying the system. The system is based on a PKI (Public Key Infrastructure) encryption system and is provided with a transmitting end, a receiving end and a could security service end, wherein the transmitting end is used for helping a sender to send security documents, the receiving end helps a user to receive, read and operate the security documents, and the cloud security service end is used for controlling and managing all documents in the system. According to the system and the method, the whole life cycles of the sent electronic documents are subjected to dynamic management, and various safety strategies are provided as follows: dynamic limits of authority control, operation statistics, out-of-limit recovery, moving track support, a cloud security-based work environment for sending the electronic documents containing sensitive information is constructed, and the applicable range is wide. According to the method, the operation habit of the user cannot be changed, and the cost performance is high.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a cloud security management method for confidential electronic files. Background technique [0002] Today, with increasingly detailed social division of labor, increasingly close economic exchanges, rapid changes in information technology, and rapid development and integration of various networks, information and data are showing an explosive growth trend. How to effectively protect your intellectual property rights and reduce data leakage? The resulting risk is a severe test that every user has to face. In order to solve the security problem of sensitive information, an effective method is to directly control the carrier and source of information, that is, access control and encryption of terminal data. [0003] Since confidential electronic documents are easy to copy and transmit, sovereignty control has always been a difficult problem to solve. Once the above-me...

Problems solved by technology

[0010] For life cycle management, a data leakage prevention management system that is closely related to the working environment is also adopted. This method has the limitation that legitimate users must be in a specific environment to use it, and life cycle parameters accompany electronic files in encrypted form. For those who deliberately Organizations that
