'Digital Key' Standard Uses Your Phone To Unlock Your Car (engadget.com) 158

Posted by BeauHD from the wireless-future dept.
The Car Connectivity Consortium, a mix of major smartphone and automotive brands, has posted a Digital Key 1.0 standard that will let you download a virtual key that can unlock your vehicle, start the engine and even share access with other drivers. Engadget reports: Unsurprisingly, the technology focuses on security more than anything else. Your car manufacturer uses an existing trusted system to send the digital key to your phone, which uses close-range NFC to grant access to your ride. You can't just unlock your car from inside your home, then, but this would also force would-be thieves to be physically present with your phone when trying to unlock your car. Apple, LG and Samsung are among the phone brands in the group, while car brands including BMW, Hyundai and the Volkswagen group are also onboard. There's also talk of a version 2.0 spec that will promise more interoperability between cars and mobile devices in the first quarter of 2019.

    The way things are in this industry at the moment, that is incedibly surprising to me...

      Whether it is secure or not is yet to be seen. At least you can't remotely drive the cars. Else someone will design a game where you drive a car onto a boat. And we get a few million cars stolen one night.

          I'm on my first keyless car too. It still distresses me to close the locked car door after exiting without a set of keys in my hand. I ALWAYS looked at my keys as I closed the door and I never locked my keys in the car.

      Actually phones have increased security for things like mobile payments. Rather than just a contactless tap or easily observed PIN, you have a fingerprint unlock or arbitrarily long password.

      Let's think about the security implications of unlocking/starting your car with your phone instead of the key. The key is probably just as vulnerable to theft since you have to have it on you, but has no authentication mechanism at all. No fingerprints, no passcodes, just having it unlocks and starts you car. So even if you disable authentication on your phone it's still no worse than the key.

      Modern car keys use radio comms, so no loss there. Actually the wireless comms used for mobile payments are even more secure, being extremely short range and using a well tested standard algorithm instead of the manufacturer's own concoction. Never roll your own security if you can help it.

      So all in all using your phone as a key seems like it can only be a net win. We have established that phones can securely keep secret tokens, as require for contactless payments.

      • Except having a physical key requires actually having the key in your posession. Some cars are more suceptible to hotwiring and slimjims, but thats the least common way cars are stolen and its pretty obvious when observed. I suspect with this that someone will discover a flaw in the API that allows any user to bypass authentication and execute the unlock feature. Its the same reason i dont have digital locks on my house. Why make it easy on them?

        • Except having a physical key requires actually having the key in your posession.

          Not the case with lots of new cars. Increasingly, they're all moving to RF keys, as AmiMoJo said. This is super convenient, since it means that you just have to have the key in your pocket and to be able to open the door and drive. But it also opens the keys up to relay attacks, where the key may be miles away from the car but a pair of transceivers relays the signal.

      • It depends on what you actually have to do to unlock your car with your phone. An increasingly common way to steal cars that have radio keys relying solely on proximity, is a relay attack. One guy stays at the car with a relay device, the other walks around your house with a device sniffing for your car key. Once the key is found, the devices link up over radio to relay the handshake between your car and your key. The car opens and starts, and off they go.

      Second: a key is single factor authentication. Phones can be multi-factor (you need the phone and a password for instance). Keys are also difficult to revoke. If you lose the key, you need to physically change the lock in order to get a new bitting.
      Another advantage of phone-based authentication is that you can transmit a token remotely to someone else if you want to give him access to you car. Basically the equivalent of putting car keys in someone's mailbox, but you get to keep your own key, and you don't need to actually go put it in the mailbox.

      - Creates new problems all of its very own.

      Beyond your examples, it provides a way for phone manufacturers to know when you are operating a vehicle, under the assumption that the phone used to unlock and start is the drivers. Once they have that information, how will they use it? Turning off texting and other messaging apps would certainly help solve the problem of idiots who text and drive, but how else can that information be used? What other services will be disabled if the think you are driving? Siri already won't let me open the garage door when it thinks I am driving, even if I am in my own driveway.

      That's assuming there is no backup system, and that your battery really is flat, not just unable to start the engine. Jump starting modern cars is not recommended anyways, but thankfully, flat batteries are also becoming less common (better power management).

      As with RF key fobs, the car should refuse to lock unless the phone is outside the car.

      Your phone having a virus can't affect it in any way, since it's not the phone's main processor or OS that do the unlocking, it's a separate secure element.

        Yes. It doesn't solve that. And RF range detecting the fob IN the car? That's dubious. Most cars that do this operate on the "you can't lock the door without the key in your hand" principle, not magically detecting that you left the key in the car and "not auto-locking"

Failures happen. Its murphys law. Designing to fail in a safe position is engineering design crteria.

      This sounds like other manufacturers seeing what Tesla has done and deciding to do it themselves.

      From a technical standpoint, I believe Tesla relies on Bluetooth, not NFC, but I'm not clear on much that matters. Bluetooth probably does a better job of working without having to pull your phone out.

All managed locally -- you should be able to add/remove profiles from the car itself without needing a manufacturer's service. Valet driving the car? No problem. Temporary code and their fingerprint is good for 5 starts.

Store a hash of all data locally and allow for local management. Fingerprints should be able to be added for a certain amount of trips to allow valets or service people to drive.
