Update on our new and upcoming security keys


Our current suite of products make up the first generation of products that Solokeys has released, starting with our initial Kickstarter campaign.To get more news about Cavity PCB, you can visit pcbmake official website.

Now we’re getting ready to release a new generation of products this year that completely redesign and upgrade everything we’ve done so far. With our upcoming generation, we aim to really be the best security key for consumers and enterprise. Our biggest priority with hardware was improving the NFC performance. Primarily for mobile phones, which often have relatively weak NFC readers.

Passive NFC for FIDO2 key is one of the more challenging NFC devices to get right. Most NFC devices people interact with are more like NFC tags, which are essentially just a memory with static information, and only need very little power to work. Whereas a FIDO2 device requires a full processor capable of quickly computing cryptographic operations, and requires considerable more power. So to get it to work with weak NFC readers, it requires considerable optimization. Ever hear about Moore’s law? Roughly, ever two years, the number of transistors on new processors doubles, due to semiconductor processes being able to make increasingly smaller transistors. This allows new generations of processors to keep getting “faster.”

Well, there’s a bunch of different transistor technologies. There are transistor technologies dedicated for low power applications -- and every generation provides less power consumption for the same processor.We’ve upgraded to a new microcontroller for the new Solo products, and it nominally consumes about 25% less power, while having the same performance. This is a great “free” optimization for us.

Furthermore, our new microcontroller provides hardware acceleration for cryptographic operations (like ECC signatures), allowing us to actually both improve performance while reducing power.To fulfill this, we’ll be the first to undertake a new PCB technology and epoxy filling process to guarantee a very robust and water-proof key. The PCB will have a manufactured cavity where all the components will get assembled, and then filled with transparent epoxy.
As you might notice, there’s now three side-buttons, and they are touch sensitive. So it’s easier to “press” and no stress is given on the connecting socket, as with top-facing button.

With there being more than one button, we plan to leverage multiple gesture for different applications. For example, FIDO2 can require a touch on any button to approve a request (like normal). But by pressing two buttons at once (giving the key a light “squeeze”), this could emit a static password or OTP.
