Embodiment 1

[0060] Such as figure 1 As shown, the embodiment of the present invention proposes an intrusion detection and defense method based on the DoIP protocol, and the intrusion detection and defense method includes:

[0061] S101: setting the DoIP protocol module in the external test equipment, and setting the DoIP protocol module and the DoIP intrusion detection module in the DoIP entity in the vehicle;

[0062] S102: Set the DoIP message format, DoIP message scene and DoIP message interval detection strategy in the DoIP entity in the vehicle;

[0063] Specifically, the detection strategy of the DoIP packet format includes: a packet header format detection strategy, and a packet type, packet length, and packet transport layer protocol detection strategy;

[0064] The packet header format detection strategy is the detection strategy of the legal value domain of the packet header parameter, and the packet header parameter includes protocol version information, protocol version bitwi...

Embodiment 2

[0083] On the basis of the above-mentioned embodiment 1, in the embodiment of the present invention, the method further includes: the in-vehicle DoIP entity detects the packet header format, the packet type, and the In the process of the message length, after detecting and learning that the DoIP message is an illegal message, notify its DoIP protocol module to send a negative response, and the DoIP intrusion detection module records the error log of the DoIP message and finishes exiting; In the process of detecting the message transport layer protocol, the working scene of the message and the message interval through its DoIP intrusion detection module, the internal DoIP entity detects that the DoIP message is an illegal message, and intrudes through the DoIP The detection module records the error log of the DoIP message and exits.

[0084] The DoIP entity in the vehicle also includes before detecting the packet header format by its DoIP intrusion detection module: the DoIP en...

Embodiment 3

[0095] On the basis of the above-mentioned embodiment 1 or embodiment 2, in the embodiment of the present invention, the DoIP intrusion detection module is also set in the external test equipment; DoIP message format, DoIP message scene and DoIP message are set in the external test equipment The detection strategy of the message interval; when the external test equipment receives the diagnostic communication response of the DoIP entity in the vehicle, the external test equipment performs the DoIP message format, DoIP message scene and DoIP message sequentially according to the detection strategy. Text gap detection.

Abstract

The invention provides an intrusion detection defense method and system based on a DoIP protocol. The method comprises the steps of arranging a DoIP protocol module in external test equipment, and arranging the DoIP protocol module and a DoIP intrusion detection module in an in-vehicle DoIP entity; setting a DoIP message format, a DoIP message scene and a DoIP message interval detection strategy in the in-vehicle DoIP entity; and when the external test equipment carries out diagnosis communication on the in-vehicle DoIP entity, enabling the in-vehicle DoIP entity to detect a DoIP message format, a DoIP message scene and a DoIP message interval in sequence according to the detection strategy. According to the invention, the DoIP intrusion detection module can firstly detect the DoIP message, identify abnormities such as the message header format, the message type, the message length, the message request interval, the message transport layer protocol type, the message request response interval and the like in different working scenes, filter abnormal illegal messages, and improve the security legality of the DoIP message.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an intrusion detection and defense method and system based on the DoIP protocol. Background technique [0002] With the development of the mobile Internet and the improvement of the performance of embedded processors, intelligent connected vehicles have become a research hotspot and a new driving force for industrial growth in the fields of global automobiles and the Internet. At present, functions such as remote upgrade (Over The Air, OTA), remote diagnosis (On Board Diagnostics, OBD / Unified Diagnostic Services, UDS), ADAS (Advanced Driving Assistance System), V2X (Vehicle to everything), and automatic driving have begun to be gradually realized. , the application prospects of communication protocols based on vehicle Ethernet are becoming more and more broad, especially the DoIP (Diagnostic communication over Internet Protocol) protocol is more and more widely used, and t...
