[STDS-802-16-MOBILE] 802.16e / TTA Security Compatibility



Title: Message
To Jeff Mandin (802.16e Security AdHoc Chair),
 
Jeff,
 
It has come to light that there is an issue with the PKM version negotiation mechanism in 802.16 if we are to achieve security compatibility with the TTA specification.
 
In 802.16e, new, non backwards compatible functionality, must be associated with a new PKM version (e.g. 2) so that legacy stations can interoperate with .16e stations, using the version negotiation mechanism to enable any new funcitonality that is supported.
 
The current TTA specifcation supports only an EAP authentication mechanism without a version negotiation.
 
We would like to request (through you as security adhoc chair) that the 802.16-TTA Liasion request that the IEEE work with the TTA to resolve this potential incompatibility between devices conformant to either standard.
 
Regards,
