Summary:

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
