Message

Handshake

Message sent to initialize an S2 session.

When starting a new S2 session, Handshake should be the first message sent from both sides. The CEM should then send a HandshakeResponse to establish the S2 protocol version used in the session. The handshaking process should always occur at the start of a session, even if the specific CEM and RM already have many succesfull S2 sessions behind them.
