Abstract

The present disclosure relates to a method and system for detecting intrusion in a distributed field bus of a vehicle network. An intrusion detection system (IDS) is used to detect intrusion in the network. In a network comprising a plurality of nodes, the IDS is configured in each of the plurality of nodes. The IDS in a first node configured in a transmission mode, receives at least one message signal. A hash function is performed on at least one message signal for generating a first Honeypot (HPT) signal. Simultaneously, the first node transmits the first HPT signal to the second node. The first node and the second node generates a reference HPT and second HPT respectively by using an echo-hash function. The IDS detects intrusion based on a comparison of the reference HPT and the second HPT. The method is independent of network traffic timing and can be performed in real-time.

Description

[0001] Preface [0002] The following description describes, inter alia, the invention and the method for its realization: technical field [0003] This article deals with cybersecurity. More specifically, but not specifically, this document relates to methods and systems for detecting intrusion into a distributed Fieldbus vehicular network. Background technique [0004] Cars are usually equipped with multiple electronic control units (ECUs) for controlling and operating the car. An automobile's on-board network consists of several ECUs connected by multiple distributed fieldbus networks. ECUs communicate with each other, or with a gateway / main controller unit (MCU) using standard in-vehicle fieldbus protocols such as Controller Area Network (CAN), LIN (Local Interconnect Network), FlexRayTM and MOSTTM (Media Oriented System Transport) . Recent innovations in automotive require vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) short-range communications as wel...
