This is a straight-forward and clear document that defines several new
cipher suites for the Transport Layer Security (TLS) protocol version
1.2 and higher, based on the Ephemeral Elliptic Curve Diffie-Hellman
with Pre-Shared Key (ECDHE_PSK) key exchange together with the
Authenticated Encryption with Associated Data (AEAD) algorithms
AES-GCM and AES-CCM. The document is well written and I appreciate the
effort to clarify in the Introduction the context, what was missing,
and why the document is necessary. One issue raised in my initial
review for draft-03 was addressed, discussed and draft-04 includes
useful clarification text. 

The document is Ready
