NFC+BLE solution

So, NXP's proposition here is to leverage NFC for secure pairing and let BLE do data link -- for the automotive market.

I find it interesting, especially when car OEMs might fear that BLE's security -- in the current generation of spec -- is not strong enough. What's your view on this?

I do not want a vehicle with the ability to communicate with another vehicle.  It will be a Hacker's wet dream coming true.  Given the number of hackers available and their propensity to collaborate on complex issues it will only be a matter of months if not weeks before the whole house of cards is compromised. Do you really want to see what hackers can conjure up for a doomsday exploit on automobiles?

@wcmoore: But automated cars would be zooming out of vision pretty soon, and they would be connected to a cloud using a dashboard interface. So even if your car doesn't support peer-to-peer communication, even then it is at risk of being hacked, since a cloud can go down anytime and systems may be breached.

@junko: secure pairing and then data linking could do well enough with current generation of cars, but OEMs are looking at a long time solution, a solution that won't be much modified for at least half a decade. It is true that BLE's security is getting increasingly weaker with time, and a day won't be far when bypassing BLE data linking would be a piece of cake.

This system of encrypted key acknowledgement may be a very good solution to expensive anti-theft systems. Not just that, in the event of a car window smash, the car would only start if the VR system of the car (since we are readily talking about IOT) recognises the voice of the driver of the car. If a car is stolen via other means (like we see in Gone in Sixty Seconds) then the car should have a basic security that wouldn't let any unknown entity inside the car start it even by using chords and cables under the dashboard.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
