Hono Botef930712021-04-08 01:12:09 +00001782<p>The Device Registry component provides an exemplary implementation of Eclipse Honoâ„¢&rsquo;s <a href="/hono/docs/1.0/api/device-registration/">Device Registration</a>,
hono Botb4b50ad2020-02-06 21:23:45 -05001783<a href="/hono/docs/1.0/api/credentials/">Credentials</a>, <a href="/hono/docs/1.0/api/tenant/">Tenant</a> and <a href="/hono/docs/1.0/api/device-connection/">Device Connection</a> APIs.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05001784<p>Protocol adapters use these APIs to determine a device&rsquo;s registration status, e.g. if it is enabled and if it is registered with a particular tenant, and to authenticate a device before accepting any data for processing from it.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05001785<p>There is no particular technical reason to implement these three APIs in one component, so for production scenarios there might be up to three different components each implementing one of the API&rsquo;s.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05001786<p>The Device Registry component also exposes <a href="/hono/docs/1.0/user-guide/device-registry/">HTTP based resources</a> for managing tenants and the registration information and credentials of devices.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05001787<p>The Device Registry is implemented as a Spring Boot application. It can be run either directly from the command line or by means of starting the corresponding <a href="https://hub.docker.com/r/eclipse/hono-service-device-registry/">Docker image</a> created from it.</p>

hono Botb4b50ad2020-02-06 21:23:45 -05002092<p>Since the secure port may need different visibility in the network setup compared to the secure port, it has it&rsquo;s own binding address <code>HONO_REGISTRY_AMQP_INSECURE_PORT_BIND_ADDRESS</code>.

hono Botb4b50ad2020-02-06 21:23:45 -05002138<p>The Device Registry supports devices to <em>act on behalf of</em> other devices. This is particularly useful for cases where a device does not connect directly to a Hono protocol adapter but is connected to a <em>gateway</em> component that is usually specific to the device&rsquo;s communication protocol. It is the gateway component which then connects to a Hono protocol adapter and publishes data on behalf of the device(s). Examples of such a set up include devices using <a href="https://www.sigfox.com">SigFox</a> or <a href="https://lora-alliance.org/">LoRa</a> for communication.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05002139<p>In these cases the protocol adapter will authenticate the gateway component instead of the device for which it wants to publish data. In order to verify that the gateway is <em>authorized</em> to publish data on behalf of the particular device, the protocol adapter should include the gateway&rsquo;s device identifier (as determined during the authentication process) in its invocation of the Device Registration API&rsquo;s <em>assert Device Registration</em> operation.</p>
Hono Botef930712021-04-08 01:12:09 +00002140<p>The Device Registry will then do the following:</p>
2141<ol>
2142<li>Verify that the device exists and is enabled.</li>
2143<li>Verify that the gateway exists and is enabled.</li>
2144<li>Verify that the device&rsquo;s registration information contains a property called <code>via</code> and that its value is either the gateway&rsquo;s device identifier or a JSON array which contains the gateway&rsquo;s device identifier as one of its values.</li>
2145</ol>
hono Botb4b50ad2020-02-06 21:23:45 -05002146<p>Only if all conditions are met, the Device Registry returns an assertion of the device&rsquo;s registration status. The protocol adapter can then forward the published data to the AMQP Messaging Network in the same way as for any device that connects directly to the adapter.</p>
hono Botb4b50ad2020-02-06 21:23:45 -05002147<p>The example configuration file (located at <code>/deploy/src/main/deploy/example-device-identities.json</code>) includes a device and a corresponding gateway configured in this way.</p>
