Abstract
In a method and a device for detecting anomalies in data in data traffic across a communication network in a vehicle, the device encompasses a plurality of hardware interfaces and a monolithic coupling element designed for transmitting data arriving at one of the hardware interfaces in a data packet via at least one of the hardware interfaces and analyzing the data packet or a copy of the data packet for a detection of anomalies in the data of the communication network or of a subsystem of the communication network connected to one of the hardware interfaces.
Claims13
A device comprising:
- a plurality of hardware interfaces;
- and
- a monolithic coupling element, wherein the coupling element is configured to:
- transmit data that arrived at one of the hardware interfaces via at least one of the hardware interfaces and in a data packet;
- and
- analyze the data packet or a copy of the data packet and thereby detect an anomaly in data of data traffic of a communication network of a vehicle or of a subsystem of the communication network connected to one of the hardware interfaces.
A communication network for a vehicle, the communication network comprising:
- a gateway;
- at least one domain controller communicatively connected to the gateway;
- and
- at least one controller connected to the at least one domain controller for communication;
- wherein:
- the at least one domain controller or the gateway includes:
- a plurality of hardware interfaces;
- and
- a monolithic coupling element;
- and
- the coupling element is configured to:
- transmit data that arrived at one of the hardware interfaces via at least one of the hardware interfaces and in a data packet;
- and
- analyze the data packet or a copy of the data packet and thereby detect an anomaly in data of data traffic of a communication network of a vehicle or of a subsystem of the communication network connected to one of the hardware interfaces, the communication network or subsystem including the at least one domain controller and the at least one controller.
A method for detecting an anomaly in data of data traffic across a communication network in a vehicle, the method comprising:
- one of a plurality of hardware interfaces receiving a data packet;
- a monolithic coupling element:
- transmitting data in the data packet via at least one of the hardware interfaces;
- and
- analyzing the data packet or a copy of the data packet and thereby detect the anomaly in data of the communication network or of a subsystem of the communication network connected to one of the hardware interfaces.
A non-transitory computer-readable medium on which are stored instructions that ae executable by a processor of a monolithic coupling element and that, when executed by the processor, cause the processor to perform a method for detecting an anomaly in data of data traffic across a communication network in a vehicle, the method comprising:
- a monolithic coupling element:
- transmitting data, which was received in a data packet at one of a plurality of hardware interfaces, via at least one of the hardware interfaces;
- and
- analyzing the data packet or a copy of the data packet and thereby detect the anomaly in data of the communication network or of a subsystem of the communication network connected to one of the hardware interfaces.
