Key management is considered as the fundamental part of any secure communication. A secure wireless sensor network communication protocol relies on an efficient key management system. In sensor networks some random pre-distribution schemes are proposed for key management protocols. Connectivity and resiliency are two important criteria in key management. There is a trade-off between connectivity and...
Muli-hop cellular network is a promising network architecture which incorporates the ad hoc characteristic into the cellular system aiming to improve current cellular network performance. Unlike single hop cellular network, due to involving autonomous devices in packet forwarding, routing process suffers from new security challenges which endanger the practical implementation of the network. One security...
Key management has become a challenging issue in the design and deployment of secure wireless sensor networks. A common assumption in most existing distributed key management schemes is that all sensor nodes have the same capability. However, recent research works have suggested that connectivity and lifetime of a sensor network can be substantially improved if some nodes are given greater power and...
