Security in mobile ad hoc networks is difficult to achieve, notably because of the vulnerability
of wireless links, the limited physical protection of nodes, the dynamically changing …

The wireless and dynamic nature of mobile ad hoc networks (MANETs) leaves them more
vulnerable to security attacks than their wired counterparts. The nodes act both as routers …

The topic of information theoretic security is introduced and the principal results in this area
are reviewed. The basic wire-tap channel model is considered first, and then several specific …

Secure operation of the routing protocol is one of the major challenges to be met for the
proliferation of the mobile ad hoc networking (MANET) paradigm. Nevertheless, security …

We consider the problem of incorporating security mechanisms into routing protocols for ad
hoc networks. Canned security solutions like IPSec are not applicable. We look at AODV [21] …

In contrast with conventional networks, mobile ad hoc networks usually do not provide
online access to trusted authorities or to centralized servers, and they exhibit frequent …

Secure and reliable group communication is an active area of research. Its popularity is
fueled by the growing importance of group-oriented and collaborative applications. The …

So far, research on mobile ad hoc networks has been forcused primarily on routing issues.
Security, on the other hand, has been given a lower priority. This paper provides an …

A relative newcomer to the field of wireless communications, ad hoc networking is growing
quickly, both in its importance and its applications. With rapid advances in hardware …

We propose a new routing technique called Security-Aware ad hoc Routing (SAR) that
incorporates security attributes as parameters into ad hoc route discovery. SAR enables the …
