## OpenSK
|
|
|
|
This repository contains a Rust implementation of a
|
|
[FIDO2](https://fidoalliance.org/fido2/) authenticator.
|
|
We developed OpenSK as a [Tock OS](https://tockos.org) application.
|
|
|
|
We intend to bring a full open source experience to security keys, from
|
|
application to operating system. You can even 3D print your own open source
|
|
enclosure!
|
|
You can see OpenSK in action in this
|
|
[video on YouTube](https://www.youtube.com/watch?v=klEozvpw0xg)!
|
|
|
|
### FIDO2
|
|
|
|
The stable branch implements the
|
|
[CTAP2.0 specification](https://fidoalliance.org/specs/fido-v2.0-ps-20190130/fido-client-to-authenticator-protocol-v2.0-ps-20190130.html)
|
|
and is FIDO certified. OpenSK supports U2F, and non-discoverable credentials
|
|
created with either protocol are compatible with the other.
|
|
|
|
If you want to use features of the newer FIDO 2.1, you can try our
|
|
[develop branch](https://github.com/google/OpenSK/tree/develop). This version is
|
|
NOT certified and less thoroughly tested though. If you plan to add features to
|
|
OpenSK, you should switch to develop.
|

|
### :warning: Disclaimer
|
|
|
|
This project is **proof-of-concept and a research platform**. It is **NOT**
|
|
meant for a daily usage. The cryptography implementations are not resistent
|
|
against side-channel attacks.
|
|
|
|
We're still in the process of integrating the
|
|
[ARM® CryptoCell-310](https://developer.arm.com/ip-products/security-ip/cryptocell-300-family)
|
|
embedded in the
|
|
[Nordic nRF52840 chip](https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fcryptocell.html)
|
|
to enable hardware-accelerated cryptography. Our placeholder implementations of required
|
|
cryptography algorithms (ECDSA, ECC secp256r1, HMAC-SHA256 and AES256) in Rust are research-quality
|
|
code. They haven't been reviewed and don't provide constant-time guarantees.
|
|
|
|
## Hardware
|
|
|
|
You will need one the following supported boards:
|
|
|
|
* [Nordic nRF52840-DK](https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-DK)
|
|
development kit. This board is more convenient for development and debug
|
|
scenarios as the JTAG probe is already on the board.
|
|
* [Nordic nRF52840 Dongle](https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF52840-Dongle)
|
|
to have a more practical form factor.
|
|
* [Makerdiary nRF52840-MDK USB dongle](https://wiki.makerdiary.com/nrf52840-mdk/).
|
|
* [Feitian OpenSK dongle](https://feitiantech.github.io/OpenSK_USB/).
|
|
|
|
## Installation
|
|
|
|
To install OpenSK,
|
|
1. follow the [general setup steps](docs/install.md),
|
|
1. then continue with the instructions for your specific hardware:
|
|
* [Nordic nRF52840-DK](docs/boards/nrf52840dk.md)
|
|
* [Nordic nRF52840 Dongle](docs/boards/nrf52840_dongle.md)
|
|
* [Makerdiary nRF52840-MDK USB dongle](docs/boards/nrf52840_mdk.md)
|
|
* [Feitian OpenSK dongle](docs/boards/nrf52840_feitian.md)
|
|
|
|
To test whether the installation was successful, visit a
|
|
[demo website](https://webauthn.io/) and try to register and login.
|
|
Please check our [Troubleshooting and Debugging](docs/debugging.md) section if you
|
|
have problems with the installation process or during development. To find out what
|
|
else you can do with your OpenSK, see [Customization](docs/customization.md).
|
|
|
|
## Research
|
|
|
|
We implemented post-quantum cryptography on OpenSK. The code is released under
|
|
the [hybrid-pqc tag](https://github.com/google/OpenSK/releases/tag/hybrid-pqc).
|
|
Our [paper](https://research.google/pubs/pub51659/) was published in the ACNS
|
|
Secure Cryptographic Implementation workshop 2023.
