The initiator (sender) generates an ephemeral secret called as (E_initiator), and likewise very own identification essential termed as (I_initiator). Now a 16 digit Master_secret code is created in the following layout;

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