USB-C will become safer



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.

The USB-C authentication press release is described in more detail, but here are the highlights of the feature: [1

9659007] A standard protocol for authenticating certified USB-C chargers, devices, cables, and power sources.
  • Support for authentication via USB data bus or USB Power Delivery communication channels.
  • Products using the authentication protocol retain control the security policies to be implemented and enforced.
  • Relies on 128-bit security for all cryptographic methods
  • The specification refers to existing internationally accepted cryptographic methods for certificate format, digital signature, hash and random number generation [19659012] Of course, device manufacturers and operating system developers must use the USB -C Authentication before it offers anything useful, and that's the biggest drawback – this is just a suggestion at the moment, not a requirement. Hopefully, most manufacturers will recognize the value of such a system and add it voluntarily.
