5.11 Constrained actuator as ADN with security

5.11.1 Profile description

The profile defines constraint actuator that is powered by battery and intended to be used for years after deployment without any human interference for maintenance. Therefore, the function of constraint actuator needs to be very limited.

An actuator is intended to be receiving control command from CSE via notification or other means. The actuator then actuates according to the control command.

The actuator needs to receive control command. As a result, the actuator needs to be request reachable to receive notification or be able to start a polling channel. There is needed some context resource architecture like the AE resource, the container resource etc. The resource architecture can be pre-configured in order to minimize the complexity of the constraint actuator. Also, the constrained actuator is configured with security credentials such as trust anchor and certificate for allowing securing communication with the CSE.

5.11.2 Profile usage examples

Switches deployed along the street light to switch on or off the street light remotely.
