“By opening up OpenSK as a research platform, our hope is that it will be used by researchers, security key manufacturers, and enthusiasts to help develop innovative features and accelerate security key adoption,” they said. Still, they made sure to note that their implementation was not officially tested and isn’t FIDO Certified. Google successfully tested OpenSK on a board and USB dongle by Nordic Semiconductor, chosen because they support all major transport protocols mentioned by the FIDO2 specification.

We’ve done this to encourage everyone to build upon the work.” Our TockOS contributions, including our flash-friendly storage system and patches, have all been upstreamed to the TockOS repository. TockOS, with its sandboxed architecture, offers the isolation between the security key applet, the drivers, and kernel that is needed to build defense-in-depth. “Rust’s strong memory safety and zero-cost abstractions makes the code less vulnerable to logical attacks. “Under the hood, OpenSK is written in Rust and runs on TockOS to provide better isolation and cleaner OS abstractions in support of security,” Elie Bursztein, Google’s Security & Anti-abuse Research Lead, and Jean-Michel Picod, Software Engineer, Google, explained. OpenSK isan open-source implementation for security keys that supports both FIDO U2F and FIDO2 standards. Includes an easy-click button, functioning indicator light, and easily attach it to your keychain.Google has open-sourced OpenSK, firmware that, combined with an affordable chip dongle, allows you to make your own security key to use for authentication purposes. Also, crafted from a durable aluminum alloy to protect the Key from drops, bumps and scratches. More convenient than other 2 step verification methods.ĭesigned with a 360° rotating metal cover that shields the USB connector when not in use. Just one simple press to login into your account. The embedded memory only stores the paired public and private keys that are generated by the local system. The key will not read or store any information from your computer or online accounts.
