USB 3.0 100W Power Standard Seeks To End Proprietary Chargers 247

judgecorp writes "The USB 3.0 Promoter Group has published a Power Delivery standard which will deliver up to 100W. The specification (press release with link to full details) includes new bi-directional — and backward compatible — USB cables, and has been proposed as the new connector between mains adapters and laptops, eliminating e-waste by standardizing a proprietary component." At home, only having to run one cable to the wall might be nice, and being able to grab some juice from any friend may end the disaster that is forgetting your laptop power brick when on the road. And imagine only having to pack a single power hub instead of three or four redundant transformers (how many people don't use their laptop to charge their phone nowadays?).

    Ha, my current laptop runs at 20V @ 11A so looks like I won't be running something like this beast on it.

    Does anyone else think this could be a future attack vector? If use existing terminology, the charger is the host and the laptop is the client, what negotiation takes place before more advanced signalling occurs other than something to negotiate what power is required? Basically, what's to stop an attacker putting some sort of malware on the charger, either something to exploit a driver or an actual executable payload on mass media?

You might have mail.
