USB chargers and devices are universally accessible and easy to use, but they come with a host of potential security risks, namely the spread of malware from infected devices, and data leakage should a device fall into the wrong hands.
Now, the USB Implementers Forum (USB-IF) — the big dog in the advancement of USB tech — has launched its USB Type-C Authentication Program, which will help mitigate these issues.
The program defines the optimal cryptographic-based authentication for USB-C devices and chargers. Any host system using this protocol will be able to confirm the authenticity of a device or charger, including descriptors and capabilities, right at the moment a connection is made.
It’s all beyond me but there’s more at the link.
