[802SEC] comments on the 802.21 PAR for Security Extensions
The Scope and Purpose statements in the draft PAR are very similar (below is the text I used for my evaluation) and don't quite provide the information I think those fields are intended to convey. Please consider revising the Scope and Purpose statements to improve them. I'm sorry I don't have more concrete suggestions at this time.
5.2 Scope of Proposed Standard:
- Define mechanisms to reduce the latency of authentication and key establishment signaling for handovers between access networks that support IEEE 802.21.
- Define mechanisms that provide data integrity, replay protection, confidentiality and data origin authentication to IEEE 802.21 MIH (Media-Independent Handover) protocol exchanges. Define mechanisms to enable authorization for MIH services
5.4 Purpose of Proposed Standard:
The purpose of this amendment is to
(i) reduce the latency of authentication and key establishment signaling for handovers between heterogeneous access networks and
(ii) secure MIH protocol exchanges and enable authorization for MIH services.
For guidance on differentiating the Scope and Purpose please see http://standards.ieee.org/guides/style/section4.html#755 which states:
"The scope of the standard shall explain in statements of fact what is covered in the standard and, if necessary, what is not covered in the standard. In other words, the technical boundaries of the document shall be discussed. The scope should be succinct so that it can be abstracted for bibliographic purposes." and
"A paragraph describing the purpose is not mandatory. However, if included, the purpose of the standard and its intended application shall be included in a separate subclause. The purpose shall explain why the standards project is needed."
