Re: [EVDL] EVLN: Would you crack your Tesla's Autopilot?

> Berlin researchers hacked Tesla autopilot

And this is surprising for what reason?

The first iPhone was jailbroken just 11 days after being released. 
Clever hackers rise to the challenge of new products to subvert if 
only because they can.


Makes me glad the only mission-critical microprocessor circuit in my 
EV is the CD player.

Re: [EVDL] EVLN: Would you crack your Tesla's Autopilot?

[Cor van de Water via EV]

Usually the encryption keys found on user devices are not the same ones as
used to generate the encryption, just the ones to decrypt, this is known as
asymmetric encryption. The decryption key is often referred to as the
public key, it is what anyone can openly use to decrypt what you have
encrypted with your private key, this process is not for secrecy but to
guarantee that what is present was created by you. Kinda important for a
mission critical system like autopilot to know it is running genuine Tesla
code. I have used this same protection in the past in communication devices.
At military protection level the measures are a bit more serious, I once
went through FIPS 140-2 certification. Then you learn about code and keys
destroyed as soon as tampering is detected.
Here someone modified a piece of HW to respond differently. If anything
untowards happens due to the changed functionality then the creators are
responsible, not Tesla.
Not much different from someone putting different type of brakes on their
car or swapping in a different engine...
