NextWireless Security Architecture forMJPv6

Network mobility introduces farmorecomplexity thanhostmobility. Toaddress theextensions needed fornet- workmobility, theIETFNEMO working grouphasrecently standardized thenetwork mobility basic support protocol in RFC 3963.However, inthisRFC,itisnotmentioned how Authentication Authorization andAccounting (AAA)issues are handled inNEMO environment. AlsotheuseofIPsec tosecure NEMO procedures doesnotprovide robustness against leakage ofstored secrets. Toaddress this security issue andtoachieve AAA withmobility, wepropose newhandover procedures tobe performed byMobileRouters andbyVisiting MobileNodes. Thesenewhandover procedures arebased onLeakage Resilient- Authenticated KeyEstablishment (LR-AKE) protocol. I.INTRODUCTION
