Secure communication between SAP Mobile Server and any supported back-end depends on the direction of the interaction between these components.
The EIS developer uses HTTPS to construct and send DCN requests to the listener.
For each of these EIS communication channels, you must configure the secure protocol. Otherwise, the user's credentials can potentially be exposed network sniffers. Once you have configured the secure channel, always ensure that EIS server certificates are imported into the SAP Mobile Server keystore to allow this communication.
