USB Type-C Authentication Program to restrict usage of uncertified USB-C chargers and accessories

USB Implementers Forum today announced the launch of its USB Type-C Authentication Program that brings cryptographic-based authentication for USB Type-C chargers and devices. This new program will enable host devices to protect against uncertified USB chargers. Host devices can confirm the authenticity of a USB device, USB cable or USB charger before inappropriate power or data can be transferred.

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 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.”
