struct GNUNET_CRYPTO_EccSignaturePurpose	purpose
	Purpose must be GNUNET_SIGNATURE_PURPOSE_COMMUNICATOR_UDP_HANDSHAKE.
struct GNUNET_PeerIdentity	sender
	Identity of the inititor of the UDP connection (UDP client).
struct GNUNET_PeerIdentity	receiver
	Presumed identity of the target of the UDP connection (UDP server)
struct GNUNET_CRYPTO_HpkeEncapsulation	enc
	Ephemeral key used by the sender.
struct GNUNET_TIME_AbsoluteNBO	monotonic_time
	Monotonic time of sender, to possibly help detect replay attacks (if receiver persists times by sender).

Detailed Description

Signature we use to verify that the ephemeral key was really chosen by the specified sender.

If possible, the receiver should respond with a struct UDPAck (possibly via backchannel).
