With the transition to USB-C devices for charging and data needs, it is becoming increasingly clear that the technology needs improved security. Today, the USB Implementers Forum announces such a change with the USB Type-C Authentication .
This new security feature allows devices to authenticate USB C connections for authorization during both loading and data connections. After implementation, the device will immediately check if a connected USB-C device is indeed legitimate and block or allow the connection accordingly.
Consider, for example, the benefits of using public charging stations. Currently, this poses a security risk. Once you've connected your device, what happens next is generally beyond your control. If the station is at risk, your data may be compromised. However, with USB-C authentication, the attached device may detect that the source is an incompatible charger and immediately lock access to your device before accessing data.
