| dc.description.abstract | Nodes in infrastructureless wireless networks usually have only limited energy and pose new security challenges. since traditional cryptographic operations have a high energy cost. In this thesis, new security solutions are presented to avoid using costly cryptographic operations. Two secure problems are investigated: the first is secure routing: the other is secure data aggregation. For the first problem, a randomized algorithm is proposed to defend against malicious attackers wishing to disrupt routing in wireless ad-hoc networks. For the second problem, a solution is proposed to leverage the broadcast nature of wireless medium and use a special aggregation topology, namely a clique tree, for data integrity in wireless sensor networks. With analysis and performance evaluation, both solutions are demonstrably lightweight with acceptable security features. | en |
