The topic has drifted somewhat Snipesy, we are talking about the new T87A TCM GM released on 2017 models that uses very large digital signatures to verify the flash contents, that is not something they've done before.

Its mostly to protect against terrorist/hacking, and consumer safety/security. If you cant wrap your head around that, and think its purely singly because of the "liberal tree huggers", then thats your problem and you need an education on cyber security and over-the-air wireless attacks. Modern vehicles have both cell link, and wi-fi capabilities. Do you want some punk sitting on the side of the road with a laptop shutting down your car remotely?
Most of the rest of the world has had ECM's that cant be OBD flashed for the past 10 years...we should count ourselves as extremely lucky.

LOL. Hardly the case. Check out www.youtube.com

I can wrap my head around that Ben. I just don't believe that's the main driving force behind it. Do you know you people here being hacked and can't use their vehicle? By the way I own one of those fancy vehicles.

Personally? Well no, because I dont personally know anyone who owns a 2017 vehicle.................
But this is just the beginning. Its been proven many times that its pretty easy to hack into late model vehicles and take control. Google it.
If theres a motive, and network access, anything is possible. Manufacturers just want to make it more difficult. Look at the Jeeps that had a massive recall due to a security vulnerability that allowed OTA breaches.

My guess is at some point the entire vehicle CAN communications will be encrypted using some sort of public-key cryptography system and ECM's totally locked down (well, the E92 and E80 ECM's are welded shut!). Who knows that might only be two or three years off, then we all just have to live off what is already out there that can be tuned because if you think we can break systems like RSA, DSA etc then you need to do a little more research on the subject.

Or someone can come up with a stand alone control system.

Ok but how could a 'non GM' stand alone ECM broadcast all the required CAN messages all other modules are expecting if the CAN messages are encrypted using GM's private Key from the OEM ECM? I know where you are coming from but at some point this could all end and there is NOTHING we can do about it. I don't want to be the grim reaper but that is a real possibility.

I understand you brother. That means I just won't by one for that purpose.
