Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Williams Expires May 11, 2008 [Page 3] Internet-Draft SSHv2 Channel Bindings November 2007 2. Bindings to SSHv2 channels SSHv2 [RFC4251] provides both, a secure channel and material (the SSHv2 "session ID") that is suitable for use as channel binding identifiers [I-D.williams-on-channel-bindings]. Thus it is RECOMMENDED that the SSHv2 "session ID" be used as the channel bindings for SSHv2. Williams Expires May 11, 2008 [Page 4] Internet-Draft SSHv2 Channel Bindings November 2007 3. IANA Considerations There are no IANA considerations in this document. Williams Expires May 11, 2008 [Page 5] Internet-Draft SSHv2 Channel Bindings November 2007 4.
