USB Type-C To Get protection against malicious devices
A new USB Type-C Authentication protocol of the USB Implementers Forum (USB-IF) was announced on Wednesday. The USB Type-C Authentication specification defines cryptographic-based authentication for USB Type-C chargers and devices. The certificate will be issued by DigiCert.
USB Type-C Authentication empowers host systems to protect against non-compliant USB chargers and to mitigate risks from malicious firmware/hardware in USB devices attempting to exploit a USB connection. Using this protocol, host systems can confirm the authenticity of a USB device, USB cable or USB charger, including such product aspects as the capabilities and certification status. All of this happens right at the moment a connection is made - before inappropriate power or data can be transferred.
"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. "As the USB Type-C ecosystem continues to grow, companies can further provide the security that consumers have come to expect from certified USB devices."
Key characteristics of the USB Type-C Authentication solution include:
- A standard protocol for authenticating certified USB Type-C chargers, devices, cables and power sources
- Support for authenticating over either USB data bus or USB Power Delivery communications channels
- Products that use the authentication protocol retain control over the security policies to be implemented and enforced
- Relies on 128-bit security for all cryptographic methods
- Specification references existing internationally-accepted cryptographic methods for certificate format, digital signing, hash and random number generation
USB-IF selected DigiCert to manage the PKI and certificate authority services for the USB Type-C Authentication Program. For further details, read the DigiCert announcement.
"DigiCert is excited to work with USB-IF and its CA Program Participants from the industry at large to provide the technical expertise and scale needed for the USB Type-C Authentication Program, and we look forward to implementation," said Geoffrey Noakes, Vice President, IoT Business Development at DigiCert.

Oh yeah. Your charger suddenly stops working. Why? Manufacturer issued and update which broke it. Or someone hacked it because it had actual components with data which could be altered.

Don't forget your iCharger in the car because no other usb charger will work on an iCrap device. And ofc, iCharger will not work on any other device.

So, now phone manufacturers will be able to require you to use only "authentic" chargers with your phone.....

Anyone smell Apple's "endorsing" of this?
