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...
