Abstract
A method for providing a Proof-of-Work concept in a vehicle is provided. The vehicle includes a network including at least three control units, where a first control unit sends a first message to a second control unit, the second control unit sends a second message including the first message to a third control unit, and the third control unit determines a Proof-of-Work for the second message based on at least one vehicle-specific characteristics of the network. Also, an corresponding system as well as a vehicle including such system are provided.
Claims23
A method for providing Proof-of-Work verification in a vehicle that comprises a network comprising at least three controllers, the method comprising:
- transmitting, by a first controller, a first message to a second controller, wherein the first message comprises a first timestamp issued by the first controller;
- transmitting, by the second controller, a second message comprising the first message to a third controller, wherein the second message comprises a second timestamp issued by the second controller and the first timestamp included in the first message;
- determining, by the third controller, a Proof-of-Work for the second message based on at least one vehicle-specific characteristic of the network;
- issuing, by the third controller, a third time stamp when the second message is received by the third controller;
- and
- determining, by the third controller, the Proof-of-Work based on whether a transmission time of at least one of the first and the second messages lies within a latency window based on at least one of the first, the second, and the third timestamps.
A system for providing Proof-of-Work verification in a vehicle, comprising:
- a network comprising at least three controllers, including a first controller, a second controller, and a third controller,
- wherein the first control unit is configured to transmit a first message to the second controller, wherein the first message comprises a first timestamp issued by the first controller,
- wherein the second controller is configured to transmit a second message comprising the first message to the third controller, wherein the second message comprises a second timestamp issued by the second controller and the first timestamp included in the first message, and
- wherein the third controller is configured to determine a Proof-of-Work for the second message based on at least one vehicle-specific characteristic of the network,
- wherein the third controller is configured to issue a third time stamp when the second message is received by the third controller and determine the Proof-of-Work based on whether a transmission time of at least one of the first and the second messages lies within a latency window based on at least one of the first, the second, and the third timestamps.
A vehicle, comprising:
- a network comprising at least three controllers, including a first controller, a second controller, and a third controller,
- wherein the first control unit is configured to transmit a first message to the second controller, wherein the first message comprises a first timestamp issued by the first controller,
- wherein the second controller is configured to transmit a second message comprising the first message to the third controller, wherein the second message comprises a second timestamp issued by the second controller and the first timestamp included in the first message, and
- wherein the third controller is configured to determine a Proof-of-Work for the second message based on at least one vehicle-specific characteristic of the network,
- wherein the third controller is configured to issue a third time stamp when the second message is received by the third controller and determine the Proof-of-Work based on whether a transmission time of at least one of the first and the second messages lies within a latency window based on at least one of the first, the second, and the third timestamps.
A method for providing Proof-of-Work verification in a vehicle that comprises a network comprising at least three controllers, the method comprising:
- transmitting, by a first controller, a first message to a second controller, wherein the first message comprises a first timestamp issued by the first controller;
- transmitting, by the second controller, a second message comprising the first message to a third controller, wherein the second message comprises a second timestamp issued by the second controller and the first timestamp included in the first message;
- determining, by the third controller, a Proof-of-Work for the second message based on at least one vehicle-specific characteristic of the network;
- issuing, by the third controller, a third time stamp when the second message is received by the third controller;
- and
- determining, by the third controller, the Proof-of-Work based on:
- whether a first transmission time of the first message lies within a first latency window based on the first and the second timestamps, and
- whether a second transmission time of the second message lies within a second latency window based on the second and the third timestamps.
