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.
