New USB-C protocol could save your devices from faulty chargers

USB-IF is a non-profit build specifically for the development of the USB standard, and it's being supported by companies such as Microsoft, Intel, Apple, HP, and many others.

With the USB-C Authentication in place, any host machine that receives an input from a USB-C device - say, a charger for example - will be able to accurately determine whether or not that device is authentic and whether it poses a risk to the machine and the contents therein.

Now, the USB Implementers (USB-IF) has launched a new USB Type-C Authentication Program that aims to mitigate this issue, at least to some extent.

The spec uses 128-bit security and "existing internationally-accepted cryptographic methods for certificate format, digital signing, hash and random number generation".

Trustingly plugging a USB charging cable into any available public port can leave your device open to attack from hidden malware, could cause permanent damage from a power surge and may even open the door to your personal or business data. An MFI Certified product means it's safe for your iOS device.

More bodies found in rubble after Russian apartment building collapse

No sign of progress after Trump meets lawmakers on shutdown
Even if only symbolic, the passage of the bills in the House would put fresh pressure on the president. He added: "To use the shutdown as hostage - which they had no argument against - is wrong".

USB-IF has chosen to work with DigiCert which will be the certificate authority service for the program. This could also be used in enterprise, with a company limiting access to only verified USB-C devices.

That is all marvelous, but because every tool can be a weapon when used improperly and we can't have anything nice, there are fears that this program is essentially a DRM mechanism.

"USB-IF is excited to launch the USB Type-C Authentication Program, providing OEMs with the flexibility to implement a security framework that best fits their specific product requirements", said USB-IF President and COO Jeff Ravencraft. The whole USB Type-C plan was about using one connector to support all manner of protocols, from Thunderbolt 3 to Power Delivery, and letting OEMs figure out which ones they wanted to implement.

The goal of the program is to create a secure handshake between different USB Type-C devices. More security is always a good thing, right?
