USB-IF Launches USB Type-C™ Authentication Program

BEAVERTON, Ore.–(BUSINESS WIRE)–USB Implementers Forum (USB-IF), the support organization for the
advancement and adoption of USB technology, today announced the launch
of its USB Type-C™ Authentication Program, marking an important
milestone for the optional USB security protocol. The USB
Type-C Authentication specification
defines cryptographic-based
authentication for USB Type-C chargers and devices.

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

“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.
