Certificates for the device connectivity layer

To secure the endpoints of the device connectivity layer, we use X.509 certificate Public Key Infrastructure.

The kind of certificate used differs by endpoint.

  • Application and management endpoints

    • For all application and management endpoints world-trusted certificates, issued by well-known certificate authorities, are used.
      This brings the advantage that most systems will be able to validate those certificates by default.

  • Device endpoints

    • For the device endpoints and protocol adapters we use a more narrowed down certificate approach.
      Devices often do not have the resources to maintain and validate many multiple root CAs.

    • Our device certificates are therefore all issued by the Let’s Encrypt Certificate Authority.
