It is better to store the smart key of the car in a metal empty can, why?

Just by putting in a pocket and approaching a car, there are a lot of cars using "smart keys" that cancels the lock and turns on electric equipment, but at the same time that convenience There should not be so many people who understand well that security problems exist. Some security experts who know the mechanism of the equipment well enough to keep their smart key in iron cans to protect their own cars.

Smart key realizes functions such as door unlocking by communicating with in-vehicle devices using radio waves. With the merit that it is not necessary to insert a key in the hole of the door like the key so far, and to be able to lower the risk of theft by physically imitating the key physically It is adopted in many automobiles.

However, something "loophole" and "strategy method" exists somewhere in human made things, smart key is not leaked completely and it is not safe completely.

In fact, among experts who are familiar with information about security, when keeping smart keys at home or workplace etc., they are not unprotected to key hooks etc, but put in an iron container of a size where the smart key fits into the shopoli Some people do. Moshe Shlisel, a former Israeli air force pilot and CEO of a security-related company "GuardKnox Cyber ​​Technologies" said, "In fact, some security experts can not fall asleep unless you put the smart key in an iron container There are people, too. "

The reason is that there are ways to steal a car by hacking smart key and radio wave communication of the car body. In order to judge "unlock OK" by detecting the approach of the smart key and confirming that the smart key is the correct one associated with the vehicle, the smart key is a communication based on a certain protocol Through radio waves. It has already been proven that you can intercept this communication or create a situation as if the user approached the car, to open the door, open the door, run the engine, and leave it as it is .

Thus, although not as much as the traditional physical key, there is also a strategy to smart key. So, there are people who practice "to put smart keys in iron cans" as a way to avoid getting involved in this problem.

The reason to put the smart key of the iron container, it is because the container made of iron isFaraday cageIt is possible to create a space called called. Radio waves used by smart keys is a kind of electromagnetic waves and it travels through the space without conductors such as electric wires. This radio wave can penetrate if it is some obstacle such as the wall of the building, but can not enter the Faraday cage. This is because there is a function that "the electric field lines can not penetrate into the inside surrounded by conductors and the external electric field is obstructed" such as iron.

When hacking a smart key, first bring a device that transmits the same radio waves as emitted from the vehicle to a smart key. Then, the smart key which received the radio wave reacts and emits a signal, so intercepting the radio wave creates fake communication and cancels the security of the vehicle. The defense method that uses the effect of the Faraday cage is to avoid such risk by shutting out the radio waves of the communication device that the third party can bring closer to without knowing it by a third party.

"The vulnerability exists everywhere, the smart key is the best example." "There are a number of attack methods around you, there are a number of attack methods around you.The computer of 20 years ago is" firewall It is the same as not having the mechanism such as "It was the same as if the mechanism was not in place." What happens if another person takes over the control of the car while driving his highway with his child? "It states the importance of taking measures in person.

In this way, there are security risks in the smart key, but it is the "connected car" that has the risk of becoming a big problem by spinning around this, that is, in recent years when the vehicle is connected to the Internet It's a car. In the future, as automobile IT advancement progresses, and automatic driving cars equipped with AI become popular, it is fully conceivable that the era of overflowing with vehicles connected to the Internet in the city will come. When AI is able to perform vehicle acceleration / deceleration and steering wheel operation, it is easy to imagine that when hacking is damaged, it is easy to imagine that the big influence exerted is more than "being stolen" Strong measures are required.
