This new specification will enable host systems to protect against non-compliant USB cables as well as mitigate risks from maliciously embedded hardware or software in USB devices. It also delivers enhanced security protocols.
Key characteristics of the USB Type-C™ Authentication solution include:USB-IF claims support for these new features can be implemented via software and/or firmware updates. Some devices and cables may need to be replaced though.
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
