Hi Jim,

I have a few queries related to H.235, specifically, RAS security.

   This is regarding the RAS procedures for authentication . During the GRQ-GCF
   exchange, the security info ( the secret key and the algorithmId ) gets
   established with the GK. For the subsequent RRQ, how does the GK relate the
   RRQ with the info stored ?
   Is there any mechanism for refreshing keys in RAS ?

Thanks and regards,
Aparna.
