Simphony Essentials Client Authentication

The Simphony Essentials Point of Sale (POS) and Kitchen Display System (KDS) clients connect to the cloud using HTTPS and TLS 1.2.

The software installation process, performed by the Oracle MICROS Client Application Loader application, includes an initial authentication step. This step requires the user to enter their EMC credentials, and if the user has the required privilege to connect a device to the system, the installation process proceeds.

After successful authentication, the cloud service creates a pair of RSA 2048–bit keys for each POS and KDS device. Clients use their unique RSA keys to create an authentication header for each message sent to the cloud service. The cloud service uses the corresponding key to validate message authenticity, for example whether the message was generated by a legitimate client, before processing its contents.
