On April 13, 2016, the USB 3.0 promoter group revealed that it is a policy to limit the USB Type-C authentication standard to encryption-based authentication. Using this protocol, the host system can check the safety of the USB device or the USB charger before it can perform data communication with the device, power supply, etc. This will protect your device from dangerous USB chargers that you do not get certified with, and prevent you from transferring dangerous data or unknown data to your device via USB.

For example, when a traveler attempts to charge his / her smartphone at a station terminal, if a USB Type-C authentication standard is adopted, a terminal is charged using a USB charger that is guaranteed safety even on an unfamiliar land It will become possible.

· Support the authentication of the communication channel of USB data bus or USB Power Delivery (USB standard with USB cable for all power supply up to 100 W)
· Products using authentication protocols will be implemented and implemented with security policy
- 128 bit security is adopted for encryption
· Certification format, digital signature, hash, random number generation, etc., which are internationally adopted encryption methods are used
