ECDH(E_initiator,S_recipient) ||ECDH(E_initiator,O_recipient)

Additional strong safety is additionally maintained in between the client and also server via a number of encrypted layers. This makes sure no third party can breach the wall surface as well as can get access to the carried data between customer and also server.
