Document encryption management system

Abstract

The invention discloses a document encryption management system, which can effectively prevent leakage of document information and has the advantages of automatic completion and non manual participation. The document encryption management system comprises a firewall device, an IOCP server and a client, wherein the firewall device is connected with the IOCP server, the IOCP server is connected with the client, the client subscribes a system intrusion message from the IOCP server, and the IOCP server adds the system intrusion message subscribed by the client in an access list; the firewall device detects whether the document encryption management system suffers a network intrusion attack in a real time manner, and when the firewall device detects the network intrusion attack, the firewall device sends alarm information to the IOCP server; and the IOCP server regenerates an encryption key for the client and sends a key change instruction to the client, and the client re-encrypts documents stored in a storage device managed by the client by use of the updated encryption key.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a file encryption management system. Background technique [0002] At present, the Internet is more and more widely used, and hackers intrude everywhere, which greatly affects the reliability and security of the Internet, and it is imminent to strengthen the construction of network security. Internet groups as small as enterprise intranets and as large as state-level intranets, such as public security networks and government affairs networks, are threatened by hackers all the time. When the group is hacked, it is necessary to modify and re-encrypt the secret-related files of different members of the group with a unified key, which can protect the secret-related information from being stolen again in a timely manner. In a very large group, a large number of team members are often involved. Once an intrusion occurs in the group, it is necessary to issue an intrusion warning to a...

AI Technical Summary

Problems solved by technology

[0010] (1) The step of notifying the group administrator of the intrusion detection results in the above process is relatively risky. Since manual work cannot be done 24 hours a day and general network intrusions occur during non-working hours, it often waits until the group management Investigators discovered that the information had already been leaked after the intrusion

[0011] (2) The connection between each step of the process is manually operated, the response time is too long and the result of the operation cannot be fed back to the group administrator in time

The workload of the operation is relatively large, and manual inspection and modification are often unable to be carried out comprehensively
