FIDO Device Onboard (FDO) Protocol Reference Implementation (PRI) Quick Start

This is a reference implementation of the FDO v1.1 Proposed Standard published by the FIDO Alliance. It provides production-ready implementation for the protocol defined by the specification. It also provides example implementation for different components to demonstrate end-to-end execution of the protocol. Appropriate security measures should be taken while deploying the example implementation for these components.

System Requirements:

  • Ubuntu (20.04, 22.04) / RHEL (8.6, 8.8) / Debian 11.4. +
  • Maven 3.6.3.
  • Java 17.
  • Haveged.
  • OpenSSL 3.0.13.
  • Curl 8.6.0.
  • Docker engine (minimum 20.10.10, Supported till version 25.0.3) / Podman engine (For RHEL) 3.4.2+
  • Docker-compose (minimum version 1.29.2) / Podman-compose 1.0.6(For RHEL)

+Supported list of Host operating systems.

NOTE: FDO service require strong random number generation in order to perform the required cryptographic functions. The FDO servers will hang on startup waiting for sufficient entropy unless the system continuously supplied random data.

  • sudo apt-get install -y haveged will ensure the system fdo services are running on have sufficient entropy.

Source Layout

For the instructions in this document, <fdo-pri-src> refers to the path of the FDO PRI folder 'pri-fidoiot'.

FDO PRI source code is organized into the following sub-folders.

  • component-samples: It contains all the normative and non-normative server and client implementation with all specifications listed in the base profile.

  • protocol: It contains implementations related to protocol message processing.

Building FDO PRI Source

FDO PRI source is written in Java 17 and uses the Apache Maven* software.

The list of ports that are used for unit tests and sample code:

Port Description
8038 manufacturer https port
8039 manufacturer http port
8040 rv http port
8041 rv https port
8042 owner http port
8043 owner https port
3306 PRI Service Database port
8070 reseller http port
8072 reseller https port
8080 aio http port
8082 aio H2 Console port
8083 manufacturer H2 Console port
8084 rv H2 Console port
8085 owner H2 Console port
8073 reseller H2 Console port
8443 aio https port

Use the following commands to build FDO PRI source.

$ cd <fdo-pri-src>
$ mvn clean install

or FDO PRI source can be built using docker container. REFER

The build creates artifacts which will be used in the rest of this guide.

The runnable artifacts can be found in <fdo-pri-src>/component-samples/demo/.

NOTE: Export the following variable JDK_JAVA_OPTIONS="--add-opens java.base/java.lang=ALL-UNNAMED", if you are facing ClassFormatError exception while building using maven.

NOTE: If build is taking a lot of time in RHEL*, check the entropy of machine using cat /proc/sys/kernel/random/entropy_avail and make sure it's a multiple of 1000. If it's not a multiple of 1000, then run the following commands: sudo yum install rng-tools -y and sudo service rngd start.

NOTE: Before starting the container on an open network, ensure that all the proxy settings are disabled, if any, and then proceed with starting the container.

Credential storage

Credentials are defined in the <fdo-pri-src>/component-samples/demo/{component}/service.env for each service and will be made available as environment variables to each docker/podman container.

aio/service.env manufacturer/service.env owner/service.env reseller/service.env rv/service.env

The following passwords are defined in each service.env:

Environment Variable Description
db_user database user account.
db_password database password
api_password defines the DIGEST REST API password
encrypt_password keystore encryption password
ssl_password Https/web server keystore password
user-cert File containing Client keypair (mTLS)
ssl-ca File containing the CA certificate of Server (mTLS)
api_user Field containing Client's certificate details (mTLS)
useSSL Boolean value specifying SSL connection with Database
requireSSL Boolean value specifying SSL connection with Hibernate ORM

Keystores containing private keys can be stored in the database - <fdo-pri-src>/component-samples/demo/{component}/app-data/emdb.mv.db as well as in the mounted file system. During runtime, the deployer can decide the mode of Keystore IO by activating the required worker class.

keys_gen.sh can be used to generate random passwords for each service.env.

NOTE: Changing the database password after the H2 database has been created requires the database file to be deleted and recreated.

Generating sample certificates and random passwords

  1. Generating demo certificate authority KeyPair and certificate

    cd <fdo-pri-src>/component-samples/demo/scripts
bash demo_ca.sh

    NOTE: Configure the properties of demo-CA by updating root-ca.conf.

  2. Generating Server and Client Keypair and certificates.

    cd <fdo-pri-src>/component-samples/demo/scripts
bash web_csr_req.sh
bash user_csr_req.sh

    NOTE: Both Server and Client certificates are signed by the previously generated demo-CA. Moreover, we can configure the properties of Server and Client certificates by updating web-server.conf and client.conf respectively. Learn how to configure Server and Client Certificates.

  3. Running keys_gen.sh will generate random passwords for the all http servers and creates secrets folder containing all the required .pem files of Client, CA and Server component.

    $ cd <fdo-pri-src>/component-samples/demo/scripts
$ ./keys_gen.sh

    A message "Key generation completed." will be displayed on the console.

    Credentials will be stored in the secrets directory within <fdo-pri-src>/component-samples/demo/scripts.

    NOTE: Execute the following command to add hosted rendezvous certificates to the java client trust stores.

    $ echo | openssl s_client -proxy ${https_proxy_host}:${https_proxy_port} -showcerts -connect fdorv.com:443 2>/dev/null | sed -n '/-----BEGIN CERTIFICATE-----/, /-----END CERTIFICATE-----/p' >> ./secrets/ca-cert.pem

  4. Copy both secrets/ and service.env file from <fdo-pri-src>/component-samples/demo/scripts folder to the individual components.

    NOTE: Don't replace service.env present in the database component with generated service.env in scripts folder.

    $ cd <fdo-pri-src>/component-samples/demo/scripts
$ cp -r ./secrets/. ../<component>
$ cp service.env ../<component>

    NOTE: Component refers to the individual FDO services like aio, manufacturer, rv , owner and reseller.

    NOTE: Docker secrets are only available to swarm services, not to standalone containers. To use this feature, consider adapting your container to run as a service. Stateful containers can typically run with a scale of 1 without changing the container code.

    NOTE: Make sure to clean api-user.pem of the owner component at <fdo-pri-src>/component-samples/demo/owner/secrets/ and restart owner service, if connections to the external Rendezvous service are failing. With certificates present in api-user.pem the owner component tries to perform an mTLS connection with the external Rendezvous component.

Specifying Subject alternate names for the Web/HTTPS self-signed certificate.

When the http server starts for the first time it will generate a self-signed certificate for https protocol.

The subject name of the self-signed certificate is defined in the web-server.conf and client.conf.

Uncomment subjectAltName and allowed list of IP and DNS in [alt_names] section. Example:

#[ req_ext ]
  subjectAltName = @alt_names

[ alt_names ]
  #Replace or add new DNS and IP entries with the ones required by the HTTPs/Web Service.
  DNS.1 = www.example.com
  DNS.2 = test.example.com
  DNS.3 = mail.example.com
  DNS.4 = www.example.net
  IP.1 = 127.0.0.1
  IP.2 = 200.200.200.200
  IP.3 = 2001:DB8::1

NOTE: Self-signed certificates created using the script is not recommended for use in production environments.

Starting Standalone Database for PRI servers

  1. Copy generated secrets/ folder to <fdo-pri-src>/component-samples/demo/db folder. Generate secrets

  2. Start the Database service

cd <fdo-pri-src>/component-samples/demo/db
docker-compose up --build -d/ podman-compose up --build -d

NOTE: By default, Database uses mTLS connection for jdbc. MariaDB* is used as the default database. For non-mTLS jdbc connection, set use_ssl and require_ssl property to false in service.yml of individual services.

NOTE: Follow the steps to Enable embedded H2 database

Starting FDO PRI HTTP Servers

Starting the FDO PRI All-In-One (AIO) HTTP Server

To start the server as a docker/podman container.

$ cd <fdo-pri-src>/component-samples/demo/aio
$ docker-compose up --build  -d / podman-compose up --build -d

To start the server as a standalone java application.

$ cd <fdo-pri-src>/component-samples/demo/aio
$ java -jar aio.jar

The server will listen for FDO PRI http & https messages on ports 8080 and 8443 respectively.

The all-in-one demo supports all FDO protocols in a single service by default.

Starting the FDO PRI Rendezvous (RV) HTTP Server

To start the server as a docker/podman container.

$ cd <fdo-pri-src>/component-samples/demo/rv
$ docker-compose up --build -d/ podman-compose up --build -d

To start the server as a standalone java application.

$ cd <fdo-pri-src>/component-samples/demo/rv
$ java -jar aio.jar

The server will listen for FDO PRI HTTP & HTTPS messages on port 8040 and 8041 respectively.

Starting the FDO PRI Owner HTTP Server

$ cd <fdo-pri-src>/component-samples/demo/owner
$ docker-compose up --build -d/ podman-compose up --build -d

To start the server as a standalone java application.

$ cd <fdo-pri-src>/component-samples/demo/owner
$ java -jar aio.jar

The server will listen for FDO PRI HTTP & HTTPS messages on port 8042 and 8043 respectively.

Starting the FDO PRI Manufacturer Server

$ cd <fdo-pri-src>/component-samples/demo/manufacturer
$ docker-compose up --build -d/ podman-compose up --build -d

To start the server as a standalone java application.

$ cd <fdo-pri-src>/component-samples/demo/manufacturer
$ java -jar aio.jar

The server will listen for FDO PRI HTTP & HTTPS messages on port 8039 and 8038 respectively.

Running the FDO PRI HTTP Device

Staring the FDO PRI HTTP Device

NOTE: By default the device is configured to run with the All-In-One (AIO) ports. You must edit the service.yml in the demo device directory to run with the manufacturer demo.

$ cd <fdo-pri-src>/component-samples/demo/device
$ docker-compose up --build -d

To start the Client as a standalone java application.

$ cd <fdo-pri-src>/component-samples/demo/device
$ java -jar device.jar

Running the device for the first time will result in device keys being generated and the device keys are stored in the app-data directory. Once device keys are generated the device will run the DI protocol and store the DI credentials in a file called credentials.bin.

Running device for a second time will result in the device performing TO1/TO2 protocols.

Deleting the credentials.bin file will force the device to re-run DI protocol.

Configuring FDO PRI HTTP Device

<fdo-pri-src>/component-samples/demo/device/service.yml contains the configuration of the device.

Creating Ownership Vouchers using All-In-One (AIO) demo

Before running the device for the first time start the demo aio server.

Run the demo device

As auto injection of ownership voucher is enabled in AIO by default; the ownership voucher is extended and stored in ONBOARDING_CONFIG table and the device is ready for TO1/2.

Switching between mTLS and Digest Authentication for REST endpoints

  1. Update WEB-INF/web.xml to support Digest authentication

    <security-constraint>
    <web-resource-collection>
        <web-resource-name>apis</web-resource-name>
        <url-pattern>/api/v1/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>api</role-name>
    </auth-constraint>
    <user-data-constraint>
      <transport-guarantee>NONE</transport-guarantee>
    </user-data-constraint>
  </security-constraint>

  <login-config>
      <auth-method>DIGEST</auth-method>
  </login-config>

  2. Update {server.api.user} and {server.api.password} in demo/<component>/tomcat-users.xml file.

Switching between mTLS and Basic Authentication for REST endpoints

  1. Update WEB-INF/web.xml to support Basic authentication

    <transport-guarantee>NONE<transport-guarante>
<auth-method>BASIC</auth-method>

  2. Update {server.api.user} and {server.api.password} in demo/<component>/tomcat-users.xml file.

DISCLAIMER: This authentication mechanism poses significant security risks,as credentials are transmitted in plaintext. Its usage is strongly discouraged, and any usage is undertaken at your own risk.

Creating Ownership Vouchers using Individual Component Demos

Before running the device for the first time start the demo manufacturer.

Use the following REST api to specify the rendezvous instructions for demo rv server.

POST https://host.docker.internal:8038/api/v1/rvinfo (or http://host.docker.internal:8039/api/v1/rvinfo) The post body content-type header text/plain

For authorization, users can use DIGEST AUTH with "apiUser" and api_password as defined in the manufacturer's service.env or can use CLIENT-CERT AUTH (mTLS).

POST content

[[[5,"host.docker.internal"],[3,8041],[12,2],[2,"127.0.0.1"],[4,8041]]]

Change the di-url: http://host.docker.internal:8080 in the demo device service.yml to di-url: http://host.docker.internal:8039

After Running the device the successful output would be as follows:

$ cd <fdo-pri-src>/component-samples/demo/device
$ java -jar device.jar

Notice: Use of Bouncy Castle FIPS as Security Provider in FDO Project

The PRI FIDO IOT component uses Bouncy Castle FIPS as the primary security provider for all cryptographic operations within the project with the exception of the KDF.

The KDF implementation is compliant with the FIDO specification and is not based on the Bouncy Castle FIPS.
