The Host Identity Protocol (HIP) is an inter-networking architecture and an associated set of protocols, developed at the IETF since 1999 and reaching their first stable version in 2007. HIP enhances the original Internet architecture by adding a name space used between the IP layer and the transport protocols. This new name space consists of cryptographic identifiers, thereby implementing the so-called...
A Mobile Ad-hoc Network (MANET) is a collection of autonomous nodes or terminals which communicate with each other by forming a multi-hop radio network and maintaining connectivity in a decentralized manner. Nodes in ad-hoc networks play both the roles of routers and terminals. Moreover, the routing path in ad-hoc networks is dynamic; it is not fixed as in wired networks. Therefore, some security...
Adhoc networks are self-configurable networks with dynamic topologies. All involved nodes in the network are responsible for management activities. In multihop adhoc environment, it is difficult to maintain paths through intermediate nodes, due to the mobility of nodes, nature of radio transmission etc. In the absence of an authentication mechanism, malicious nodes can easily corrupt route tables,...
Resource and cost constraints remain a challenge for wireless sensor network security. In this paper, we propose a new approach to protect confidentiality against a parasitic adversary, which seeks to exploit sensor networks by obtaining measurements in an unauthorized way. Our low-complexity solution, GossiCrypt, leverages on the large scale of sensor networks to protect confidentiality efficiently...
Mobile ad-hoc networks (MANET) have found strategic importance in real world applications like environment management, remote explorations, disaster and warfare conditions due to their dynamic, self tailoring and adaptive nature. These networks can be quickly deployed in situations where no infrastructure exists. Effective use of these networks is largely dependent on secure and reliable behavior...
