RE: [802.21] 802.21 Security PAR: Initial write-up
Happy New Year folks!
Yoshi, Here are my suggestions on the initial PAR document.
12 Scope of the Proposed Project - The TR includes intra-technology inter-domain handover and I'm not sure if the scope description " ... handovers between heterogeneous 802 systems ..." covers that. It may be easier to show figure 1 from the TR. How about this:
"This standard defines mechanisms that provide the security signaling optimization during certain handover scenarios between 802 access networks as indicated in the table below and mechanisms that provide security to MIH (Media-Independent Handover) protocol exchange based on a security association that is bound to a pair of mutually authenticated MIH entities. These mechanisms shall be defined as an amendment to the 802.21 specification.
| Intra-technology | Inter-technology | Inter-technology
| 802 to 802 | 802 to 802 | non-802 to 802
------------------------------------------------------------------------
Intra- | out of scope | in scope | out of scope
Domain | | | (for future study)
------------------------------------------------------------------------
Inter- | in scope | in scope | out of scope
Domain | | | (for future study)
"
13. Purpose of the Proposed Project - It would probably be helpful if stronger reasoning is given. Also addressing Vivek's previous comment. How about this (Some snipped from parts of the TR):
"The purpose of this project is two fold: One is to improve seamless transition between heterogeneous 802 access networks for real time sensitive applications by optimizing network access control when a mobile node transitions from one access network to another. Optimization of security signaling is especially applicable in handover scenarios where the mobile node must briefly break its active connection before being able to make a connection to the target access network. The second purpose is to provide an adequate level of protection for the MIH services and protocols by specifying standard mechanisms for MIH system authentication, access control, protocol integrity protection and protocol data confidentiality. In the current IEEE P802.21 draft [1] the general problem space of security for the MIH protocol and services is unspecified. MIH level security will be an important factor to the providers that wants to deploy these MIH services in their network and is concerned ab!
out it negatively affecting existing network services."

Ron
