MOBILE DEVICE, A VEHICLE HAVING THE SAME, AND A CONTROL METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18215315 titled 'MOBILE DEVICE, A VEHICLE HAVING THE SAME, AND A CONTROL METHOD THEREOF
The patent application describes a system where a vehicle can detect and prevent relay attacks on digital keys by utilizing channel hopping techniques.
- The vehicle receives channel hopping information and a time stamp from a communicator.
- It broadcasts a packet as an advertising signal through preset channels.
- If the advertising signal matches the response signal from a mobile device, it deactivates the digital key to prevent a relay attack.
- If the advertising signal and response signal do not match, the vehicle confirms the channel through which the response signal is received.
- If the confirmed channel matches the preset channel, the digital key is activated.
Potential Applications: - Automotive security systems - Anti-theft measures for vehicles - Preventing unauthorized access to vehicles
Problems Solved: - Preventing relay attacks on digital keys - Enhancing the security of vehicles - Ensuring only authorized access to vehicles
Benefits: - Improved vehicle security - Protection against relay attacks - Peace of mind for vehicle owners
Commercial Applications: Title: "Advanced Vehicle Security System for Preventing Relay Attacks" This technology could be marketed to automotive manufacturers, security companies, and vehicle owners looking to enhance the security of their vehicles.
Questions about the technology: 1. How does channel hopping help prevent relay attacks on digital keys? 2. What are the potential implications of not detecting and preventing relay attacks on vehicles?
Original Abstract Submitted
A vehicle may receive channel hopping information and a time stamp of a data area of a packet from a communicator; broadcast the packet as information of an advertising signal through any one of a plurality of preset channels; in response to the information of the advertising signal being identical to information of a response signal of a mobile device received through the communicator, determine as a relay attack detection and control deactivation of a digital key; in response to the information of the advertising signal being different from the information of the response signal of the mobile device, confirm a channel through which the information of the response signal is received; and in response to the confirmed channel being identical to the any one channel, control activation of the digital key.
