Laptop, desktop and smartphone manufacturers can now add authentication to their products for USB-C cables, chargers and other accessories using a USB-C connector. The USB Implementers Forum (USB-IF) has launched its USB Type-C Authentication Program. Certificates are provided by DigiCert.
USB Type-C Authentication makes it possible for host-devices to protect against non-compliant USB chargers and to secure them from malicious firmware or hardware in USB-C accessories.With the protocol, host-devices can confirm the authenticity of a USB device, USB cable or USB charger, including product properties and certification status.
Authentication happens the moment a connection is made and before inappropriate power or data can be transferred.
Manufacturers are not required to implement the protocol. For end-users it should be easier to determine whether a USB-C connected cable or device complies with the standard.
It's unknown when the first products with USB Type-C Authentication will hit the market, but manufacturer can add the feature from now on.
