Embodiment 1

[0070] In the embodiment of the present invention, the first node is a bus terminal, and the second node is a bus controller. When the message to be transmitted is transmitted from the external network to the two-wire transmission network, the bus controller receives the After transmitting the message to be transmitted, it is first necessary to determine that the industrial control protocol of the message to be transmitted conforms to the white list of the industrial control protocol. In the embodiment of the present invention, the message format of the message to be transmitted is as shown in Table 3 , including industrial control protocol header, TCP header, IP header, data information and FCS (cyclic redundancy check value):

[0071]

[0072] In the embodiment of the present invention, it can be determined whether the message to be transmitted belongs to the white list of the industrial control protocol according to the analyzed header of the industrial control protocol o...

Embodiment 2

[0085] In the embodiment of the present invention, the first node is a bus controller, and the second node is a bus terminal. The equipment in the two-wire data transmission network sends a message to be transmitted to the external network, and the bus controller receives the message to be transmitted sent by the bus terminal. message, and determine the destination IP address and the destination MAC address of the message to be transmitted, that is, the destination IP address and the destination MAC address of the message to be transmitted determined by the bus controller are the IP address and the MAC address of the bus controller, and the bus The controller determines the bus device address of the message to be transmitted according to the correspondence table in Table 1, that is, the device address of the bus controller.

[0086] Optionally, in the embodiment of the present invention, the bus controller replaces the IP address and MAC address in the message to be transmitted...

Abstract

The invention discloses an implementation method for broadband bus data deep detection on an industrial Internet field layer. The method comprises the following steps that: a first node acquires a message to be transmitted; the first node judges whether a bus equipment address belongs to a preset bus equipment address range or not according to the bus equipment address in the message to be transmitted; and if the bus equipment address belongs to the preset bus equipment address range, the first node transmits the message to be transmitted to a processor of the first node. The first node only forwards the message to be transmitted within the preset bus equipment address range, so that the message transmission security is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, and in particular to a method for implementing in-depth detection of broadband bus data at the field layer of the industrial Internet. Background technique [0002] With the development of Internet technology, various buses are widely used in industrial field automation to realize real-time monitoring of the industrial field by the control terminal, and according to different application fields, the requirements for data transmission security are also different, especially for servo, In robots and other systems that require high precision, the accuracy of on-site data and control data directly affects the security performance of the system. Network intrusion incidents often occur on the Internet, and the system is paralyzed by sending virus information to the bus system with loopholes in security detection. Such incidents jeopardize national, collective and individual security. ...
