USB Type-C Authentication Program Launched (newatlas.com) 133

With the arrival of USB-C a few years back, plugging into laptops, tablets and smartphones became even easier than before. But there are potential security risks. The USB Type-C Authentication Program launched today aims to address such issues. From a report: The new protocol from the USB Implementers Forum (USB-IF) can be used to validate the authenticity of a cable, charger or hardware at the moment of connection, and stop attacks in their tracks. The USB-IF has chosen DigiCert to operate registrations and certificate authority services for the new specification, which makes use of 128-bit cryptographic-based authentication for certificate format, digital signing, hash and random number generation.

"USB Type-C Authentication gives OEMs the opportunity to use certificates that enable host systems to confirm the authenticity of a USB device or USB charger, including such product aspects as the descriptors, capabilities and certification status," said DigiCert in a press release. "This protects against potential damage from non-compliant USB chargers and the risks from maliciously embedded hardware or software in devices attempting to exploit a USB connection."

      That was my first thought as well.

      Perhaps the EU will require that manufacturers allow use of non-vendor certified charges/devices with one click or one keystroke and that decision must be remembered for the life of the system so no more prompting will be required.

      • It's not even that, it's not "authenticating" anything except that the device vendor paid DigiCert for a certificate. Like web site certificates, it tells you absolutely nothing about the safety of the thing you're connecting to, merely that someone, whether it was a legit organisation or a hacker with a stolen credit card, decided to spend money for a certificate to lull you into a false sense of safety.

      • There are two kinds of danger for USB devices. This is intended to protect against the first: that a cheap cable from SuperGoodHappyCablesCompany advertises that it's able to carry 40W but actually catches fire if you run more than 5W through it for an extended period. This can be addressed by adding some authentication to everything in the chain so that you can drop the power when things are not certified.

      This just helps ensure that only authorized compromised cables can be used with your USB 3 device. It does NOTHING to ACTUALLY stop malicious cables being used to disable or destroy your device, since they can just take components from an authenticated cable to pass the handshake then use their own microcontroller or circuit to fry your hardware when it attempts to charge or connect over the cable.

        To be fair I think the main goal is to stop poorly manufactured cables from damaging equipment, not to defend against malicious ones. The uncertified ones can just work with data and 5V charging, but certified ones are supposed to be safe for use at 100W.

        Devices were putting themselves in danger by not having basic electrical protection on the ports. In 90s, this was such a common (and commonly solved) problem that the Tawainese motherboard manufacturers listed all sorts of per-USB-port short, over voltage, over current, etc. protections on the box.

        It became a problem again with USB 3 because the first players to the market with USB controllers didn't learn their lesson from the USB 1.0/1.1 days. There's absolutely no reason a bad USB cable should be able to kill an entire device. At worst, it should kill a single port. Ideally, it would have a replaceable/resettable fuse so you don't even lose the port.

        • by AmiMoJo ( 196126 )

          Yeah, those old USB protection circuits won't survive 20v/5A on the data lines. And even if they did, the cable catching fire would burn your house down anyway.

          In fact there exist malicious devices that destroy USB ports precisely by applying very high voltages to the data lines of USB ports.

          Also, it's even harder to protect USB 3.0 ports because they operate at higher speeds over many more lines. On USB 1.1 you had four wires to worry about, and a maximum frequency of 12MHz. On USB 3.0 with a USB-C connect

            A cert isn't going to stop a malicious or miswired cable/charger that dumps 20v on the data line from doing damage. Authorized or not, you have to handshake and that opens you up to a High voltage attack.

            But that's not even vaguely what the intent is here. It's to prevent no-name manufacturers making and selling a cable/charger that's out of spec and devices getting damaged using it. In theory if it doesn't handshake with it's certs, it will default to whatever safe level (or no access) is default.

          But that costs money as does the implementation.

          When you're selling cheap cables that are even more cheaply made...you often don't spend that money.

          • It's not up to the cable to be expensive. It's up to the device at either end to limit itself to a safe level. We've repeated the mistakes from early USB 1.0 devices. And no protecting does not cost money for implementation, at least not significantly due to the incredibly low cost of protection devices and the fact that they are often baked into the silicon itself.

            If you have a standard that auto-negotiates how to provide power, then that standard should also ensure that no possible misconnection scenario

          This issue will keep getting worse as time goes by and we demand faster and faster charging. Even now most phones play it safe by slowly ramping up current draw until the voltage starts to sag too much, figuring that is probably a safe point where the cable won't catch fire.

      The USB Type-C standard already mandates an active cable if you want to utilize the full 5A that the standard can supply. It might not have information on the condition of the cable - but nothing can prevent users from being stupid. It is just another level of security which, with all the other protections, helps prevent damage when power traverses USB.

      It is easy to add an IC to a USB connector - they are basically designed for it. See this [digikey.ca] part to see how it is typically done. So adding the ability to verify the cable does make sense for workplaces that require the security. It is just too easy to, for example, add a keylogger to a cable.

      No computer manufacturers would ever get away with requiring authenticated cables. Apple might try but the public outcry would be immense. That being said - having it as a bios setting is exactly what a certain subset of users require.
