Intrusion detection mechanism
TLDR
In this article, a method implemented on a node connected to a network bus includes: storing one or more message identifiers, the message identifiers comprising at least one message identifier identifying the node, the at least message identifier being included in a message at a time when the message is sent by the node onto the network bus; monitoring network bus traffic, the network buses traffic comprising messages transmitted by both the node and by other nodes connected to the networkbus; and alerting a processor of the node if a message transmitted on the bus by at least 1 of the other nodes is identified asAbstract:Â
In one embodiment, a method implemented on a node connected to a network bus includes: storing one or more message identifiers, the one or more identifiers comprising at least one message identifier identifying the node, the at least one message identifier being included in a message at a time when the message is sent by the node onto the network bus; monitoring network bus traffic, the network bus traffic comprising messages transmitted by the node and by other nodes connected to the network bus; and alerting a processor of the node if a message transmitted on the network bus by at least one of the other nodes is identified as having a message identifier corresponding to the at least one message identifier.read more

System and method for time based anomaly detection in an in-vehicle communication network
TL;DR: In this paper, a system and method for providing security to a network may include maintaining, by a processor, a timing model of an expected behavior of data communications over the in-vehicle communication network; receiving, by the processor, an email message sent over the network; determining, by controller, based on the model and based on a timing attribute of the message, whether or not the message complies with the model; and if the message does not comply with the message then performing at least one action related to the message.

Matthias Muth,Bernd U G Elend +1 more
TL;DR: In this paper, the authors describe a CAN device that includes a TXD input interface, an output interface, and a traffic control system connected between the TXD and output interfaces.
Patent
In-vehicle network attack detection method and apparatus
TL;DR: In this article, a learning module, a profiling module, and a detection module are presented for CAN communication attack detection, where the profiling module maintains learning statistical information received and a precollected attack type, and the detection module extracts a CAN ID and a bit stream of a data field from a real-time input CAN packet.
Patent
Methods, systems, and computer readable media for testing time sensitive network (TSN) elements
TL;DR: In this article, a test system clock is synchronized with a clock at a system under test (SUT), and a sequence of messages is generated using schedule rules associated with a TSN stream.
Patent
Modeling a clock
TL;DR: In this article, the authors describe a clock-related information for estimating the precision of a local clock at the first node relative to a clock at a second node at a monitoring module associated with a first node.

Security system and method for protecting a vehicle electronic system
Gil Litichever,Levi Ziv +1 more
TL;DR: In this article, the authors propose a security system for protecting a vehicle electronic system by selectively intervening in the communications path in order to prevent the arrival of malicious messages at ECUs, in particular at the safety critical ECUs.

Electronic system for detecting and preventing compromise of vehicle electrical and control systems
TL;DR: In this article, a method for detecting threats or attacks on an automobile network, the automobile network connected to a plurality of electronic components and an attack monitoring unit including a processor, is presented.
Patent
Security for network-connected vehicles and other network-connected processing environments
TL;DR: In this article, the authors propose a method and apparatus to provide security for a network-connected vehicle (or other networked environment) in which a predefined set of permitted operations relating to protected resources can be initiated remotely from elsewhere in the network, while security is maintained for the protected resources (for example, an engine performance optimisation control unit or air conditioning control unit within a vehicle) by preventing remote initiation of any other operations on a data processing unit which is connected to the protected resource.
Patent
Consistent application programming interface for communicating with disparate vehicle network classes
TL;DR: A computer implemented translation system provides a programming interface between a client and remote devices connected to a vehicle data network that permits programming and diagnostic procedures to be carried out without reference by the programmer to nuances of the particular network class used on the motor vehicle as discussed by the authors.
