 This is bad and bigger than jeeps.

Automakers are going to use this as propaganda to be allowed to lock down their computer stuff, essentially killing Right to Repair.

chrysler is going to be the reason your 2020 chevrolet can only be diagnosed at a chevrolet dealership at whatever rate the dealership feels like charging and will be done whenever the dealership decides to do it. New electrical parts can only be coded to your car by a chevy dealership with a chevy computer, so you can have it diagnosed, towed to an independant shop, repaired, and towed back to the dealership to have the parts activated.

Yes it is and yes it does.

Let's say, for example, the BCM sends a message to the wipers, telling them to activate. The BCM cryptographically signs the message using its private key. The wipers have the BCM's public key installed, and can verify that the message came from the BCM.

Now, let's say the infotainment system received a malicious OTA update that causes it to try to spoof messages from the BCM, telling the wipers to activate. The infotainment system does not have the BCM's private key, so it cannot sign the message.

Do you want $1,500 wiper motors? because this is how you get $1,500 wiper motors.
