Provision AWS IoT FleetWise vehicles

The Edge Agent for AWS IoT FleetWise software running in your vehicle collects and transfers data to the cloud. AWS IoT FleetWise integrates with AWS IoT Core to support secure communication between the Edge Agent software and the cloud through MQTT. Each vehicle corresponds to an AWS IoT thing. You can use an existing AWS IoT thing to create a vehicle or set AWS IoT FleetWise to automatically create an AWS IoT thing for your vehicle. For more information, see Create an AWS IoT FleetWise vehicle.

AWS IoT Core supports authentication and authorization that help securely control access to AWS IoT FleetWise resources. Vehicles can use X.509 certificates to get authenticated (signed in) to use AWS IoT FleetWise and AWS IoT Core policies to get authorized (have permissions) to perform specified actions.

Authenticate vehicles

You can create AWS IoT Core policies to authenticate your vehicles.

To authenticate your vehicle

  • To create an AWS IoT Core policy, run the following command.

    • Replace policy-name with the name of the policy that you want to create.

    • Replace file-name with the name of the JSON file that contains the AWS IoT Core policy.

    aws iot create-policy --policy-name policy-name --policy-document file://file-name.json

    Before you use the example policy, do the following:

    • Replace us-east-1 with the AWS Region where you created AWS IoT FleetWise resources.

    • Replace 111122223333 with your AWS account ID.

    This example includes topics reserved by AWS IoT FleetWise. You must add the topics to the policy. For more information, see Reserved topics in AWS IoT FleetWise.

Authorize vehicles

You can create X.509 certificates to authorize your vehicles.

To authorize your vehicle
Important

We recommend that you create a new certificate for each vehicle.

  1. To create an RSA key pair and issue an X.509 certificate, run the following command.

    • Replace cert with the name of the file that saves the command output contents of certificatePem.

    • Replace public-key with the name of the file that saves the command output contents of keyPair.PublicKey.

    • Replace private-key with the name of the file that saves the command output contents of keyPair.PrivateKey.

    aws iot create-keys-and-certificate \
    --set-as-active \
    --certificate-pem-outfile cert.pem \
    --public-key-outfile public-key.key" \
    --private-key-outfile  private-key.key"

  2. Copy the Amazon Resource Name (ARN) of the certificate from the output.

  3. To attach the policy to the certificate, run the following command.

    • Replace policy-name with the name of the AWS IoT Core policy that you created.

    • Replace certificate-arn with the ARN of the certificate that you copied.

    aws iot attach-policy \
    --policy-name policy-name\
    --target "certificate-arn"

  4. To attach the certificate to the thing, run the following command.

    • Replace thing-name with the name of your AWS IoT thing or the ID of your vehicle.

    • Replace certificate-arn with the ARN of the certificate that you copied.

    aws iot attach-thing-principal \
    --thing-name thing-name \
    --principal "certificate-arn"
