Layer-wise Security Schemes with Secure Routing Protocol for Integrated UMTS and WLAN Ad Hoc Networks

Abstract

It is well known that the Integrated Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) ad hoc network is not secure, due to the vulnerable routing infrastructure of ad hoc nodes to a variety of active attacks. In this paper, we introduce a secure, robust newly developed routing protocol, namely SNAuth_SPERIPv2, based on a Bellman Ford algorithm. It can be widely used in heterogeneous Next-Generation Networks (NGNs) on the inter-domain routing for un-trustworthy environment. A security framework is proposed for determining how the combination of the secure routing protocol and different layer security schemes (DSSS, CCMP-AES, IPSec and WTLS) should be working together against Wormhole Attack (WHA). WHA analysis and simulation results show the security scheme strength in terms of QoS metrics under CBR background traffic.
