Returning back to the CISE model, the EncryptedEntityPayload is a special entity extension of the Message class:
In the CISE node, the encryption is responsibility of the CISE servers. The actual CISE network is using encrypted payloads.
The payload attribute
EnsureEncryption
of the CoreEntityPayload must be valued to true in a constant way:
<EnsureEncryption>true</EnsureEncryption>
