A smart hot network data transmission security protection system and method

Abstract

The present application discloses a smart heat network data transmission security protection system and method. The system includes a transmission encryption system on the thermal user side and a transmission encryption system server side on the power plant side. The transmission encryption system is integrated into the thermal system in the form of a national secret security SDK User totalizer; the server side of the transmission encryption system is deployed at the data entrance and exit of the smart heating network management system server on the power plant side; the transmission encryption system establishes a key management mechanism to establish a secure data transmission between the heat user side and the power plant side The power plant side transmission encryption system server side acts as the reverse proxy server of the smart heat network management system, and at the same time authenticates the encrypted connection, encrypts the data, decrypts it and unloads it, and realizes the security protection of the data transmission of the smart heat network. The invention guarantees the integrity and confidentiality of the heat network data, strengthens the data processing capability, and improves the flexibility and usability of the system.

Description

technical field [0001] The invention belongs to the technical field of heat network data transmission security, and relates to a smart heat network data transmission security protection system and method. Background technique [0002] The smart heat network closely integrates the physical system of the traditional heat network with the business information system, and uses technologies such as big data, artificial intelligence, cloud computing, and "Internet" to collect and analyze important real-time parameter data for heating, such as pressure, instantaneous flow, Accumulated flow, collection time, valve status, available gas and other data, realize real-time monitoring of heating network, remote control command issuance. [0003] At present, smart heat network thermal users generally use wireless operator networks, and use TCP / IP protocol to transmit data to the interface platform of the power plant's smart heat network management system; the interface platform parses the...

Problems solved by technology

Important heating parameter data and remote control instructions are transmitted in plain text. Attackers can obtain the transmitted heating network data through sniffing or man-in-the-middle attacks, and then tamper with the heating network data or control instructions. The security of data transmission cannot be guaranteed. Assure

[0004] In terms of data transmission security protection technology, in the process of establishing a remote security access channel in the traditional way, a large number of keys generated will exist in the system. When the generated invalid keys are not cleared in time, a large amount of storage space will be occupied; In the heating network scenario, there will be a large number of concurrent users sending connection establishment requests to the power plant side server, which will easily bring a heavy operating burden to the entire server, resulting in slow data transmission and even service timeouts.
