New software can tell if you're using bad USB Type-C cables

A software fix for sub-par USB-C type cables is coming, thanks to USB Implementers Forum (USB-IF), which certifies cables as safe. It has announced a brand new way to ensure that your devices are protected from those bad cables.

USB 3.0 Promoter Group has announced USB Type-C Authentication specification, defining cryptographic-based authentication for USB Type-C chargers and devices. Using this protocol, host systems can confirm the authenticity of a USB device or USB charger, including such product aspects as the descriptors/capabilities and certification status. All of this happens right at the moment a wired connection is made – before inappropriate power or data can be transferred.

USB Type-C Authentication empowers host systems to protect against non-compliant USB Chargers and to mitigate risks from maliciously embedded hardware or software in USB devices attempting to exploit a USB connection. For a traveler concerned about charging his/her phone at a public terminal, their phone can implement a policy only allowing charge from certified USB chargers. A company, tasked with protecting corporate assets, can set a policy in its PCs granting access only to verified USB storage devices.




“USB is well-established as the favored choice for connecting and charging devices,” said Brad Saunders, USB 3.0 Promoter Group chairman. “In support of the growing USB Type-C ecosystem, we anticipated the need for a solution extending the integrity of the USB interface. The new USB Type-C Authentication protocol equips product OEMs with the proper tools to defend against ‘bad’ USB cables, devices and non-compliant USB Chargers.”

“USB-IF is unwavering in our mission to solidify USB Type-C as the single cable of the future,” said Jeff Ravencraft, USB-IF President and COO. “USB Type-C Authentication is an important contribution to enable a thriving ecosystem of compliant, interoperable products.”
