+## Security configuration for example apps
+
+In order for the ``consumer`` example app to be able to properly authenticate data packets
+created by the ``producer`` app, you must configure the following parameters.
+
+1. Generate example trust anchor:
+
+        ndnsec key-gen /example
+        ndnsec cert-dump -i /example > example-trust-anchor.cert
+
+2. Create a key for the producer and sign it with the example trust anchor:
+
+        ndnsec key-gen /example/testApp
+        ndnsec sign-req /example/testApp | ndnsec cert-gen -s /example -i example | ndnsec cert-install -
