Embodiment

[0045]The method for fast real-time detection and recovery of files in the operating system in this embodiment includes: a group of QCRP protocols that support file detection and file transfer; server software that supports the QCRP protocol running on the server side; running on the terminal The node supports the client software of the QCRP protocol; a simple schematic diagram of system deployment and interaction between components is shown in figure 1 shown. A set of security protocols that support file detection and file transfer are used for interactive operations between server and server, client and client, and server and client. The protocol has anti-replay and anti-tampering mechanisms to ensure that components Integrity of inter-data exchange, composed of UDP and TCP2 transmission protocols.

[0046] The main functions of the server software are file asset library storage, file asset library security policy configuration, security detection, file asset library update...

Abstract

The invention relates to a method for fast detecting and recovering files in an updating operation system in real time. The system comprises a group of QCRP protocols supporting file detection and file transmission, server software, client software and a group of security protocols, wherein the server software runs at a server and supports the QCRP protocols; the client software runs at a terminal node and supports the QCRP protocols; the group of security protocols supports file detection and file transmission, and are used for interactive operation between servers, between clients and between the servers and the clients; the protocols have playback prevention and tampering prevention mechanisms; the completeness of data interaction between components is ensured; the security protocols consist of a UPD protocol and a TCP protocol. The method has the advantages that when an abnormal file is detected and needs to be restored, equipment in a local area network is preferentially selected for file transmission, the speed is high, and the efficiency is high; when the condition that a file or a catalogue in a monitoring target needs to be updated is detected, the equipment in the local area network is preferentially selected for file transmission, the speed is high, and the efficiency is high.

Description

technical field [0001] The invention relates to a method capable of rapidly detecting and restoring files in an upgraded operating system in real time, and belongs to the technical field of information security. Background technique [0002] In a system with file detection, file recovery and upgrade functions, a server for storing file assets will be deployed. Each terminal will connect to the server and download the correct version description library (file content fingerprint) of the file for comparison and verification with the local file. Restore or upgrade local terminal files according to file detection results and policies. In the real-time detection, recovery / upgrade system, if there are a large number of files / directories in the terminal node that have abnormal changes or the server has a large number of files that need to be sent to each terminal node after being updated, the performance of the server and the network bandwidth will affect the recovery. Or the upgr...
