Tesla is working on a new key fob with auto unlocking and power dependent on the new UWB innovation that is “immune to relay attacks.”
Tesla and relay attacks
Thefts of Tesla vehicles are very uncommon in North America, however in Europe, they have some more refined cheats that dealt with a line of Tesla vehicle robberies through transfer assaults, and most vehicles haven’t been recuperated.
A relay assault for the most part comprises of utilizing a gadget that transfers the sign from a close by key coxcomb to open a vehicle.
In light of those assaults, Tesla began turning out additional layers of security with an “improved cryptography” key fob and optional “PIN to Drive” include.
Tesla has since been attempting to improve its security – even through programming updates at the key fob level.
Tesla is presently receiving UWB
Presently Tesla is hoping to add another layer of security.
As indicated by another documenting with the FCC, Tesla is incorporating another single chip Impulse “Radio Ultra Wideband” (IR‐UWB), otherwise called UWB, inside its new key coxcomb.
Tesla wrote in the new FCC recording:
“The main objective of a UWB ranging device is to provide a distance estimate, which serves as a tight upper bound for the actual distance between a sender and a receiver. In other words, the distance estimate is close to the actual distance and may be longer than the actual distance, but not shorter. In the PKE context this means that the key is not further away from the car than the estimated distance. The distance estimate is based on a Time of Flight measurement, and is immune to relay attacks. This drastically improves PHY layer security compared to an RSSI based distance measurement, which is susceptible to relay station attacks.
A UWB receiver can give an accurate distance estimate, when there is a direct line‐of sight (LOS) propagation path between the sender and the receiver. All other propagation paths are caused by reflections, hence have a longer time of flight, and will lead to a looser upper bound for the distance.”
This new innovation would be connected to another key fob, however a few telephone makers are likewise receiving it, implying that it very well may be executed to Tesla’s telephone key component.
As we announced a week ago, Tesla is making its telephone application the main key for Model S and Model X with the new updated plan, and the application is as of now the fundamental key for Model 3 and Model Y.
