A Multihop Key Agreement Scheme for Wireless Ad Hoc Networks Based on Channel Characteristics
A number of key agreement schemes based on wireless channel characteristics have been proposed recently. However, previous key agreement schemes require that two nodes which need to agree on a key are within the communication range of each other. Hence, they are not suitable for multihop wireless networks, in which nodes do not always have direct connections with each other. In this paper, we f...
متن کاملMultihop Wireless Ad Hoc Networks
An ad hoc network is a collection of mobile nodes using wireless network interfaces to communicate among themselves, discovering and routing along possibly multihop routes to each other without the assistance of fixed infrastructure. In this paper, we describe the design and demonstration of a set of simple routing protocol mechanisms that substantially improve the transmission of real-time mul...
متن کاملEÆcient Hybrid Key Agreement Protocol for Wireless Ad Hoc Networks
|Secure and eÆcient communication among a set of mobile nodes is one of the most important aspects in ad-hoc wireless networks. To ensure the security, several cryptography protocols must be implemented. Due to the resource scarcity in wireless networks, the protocols must be communication eÆcient and need as less computational power as possible. To secure the group broadcasting in wireless net...

متن کاملAuthenticated Group Key Agreement Protocols for Ad hoc Wireless Networks
The lack of fixed infrastructure, both physical and organizational, and the highly dynamic nature of ad hoc networks, presents a major challenge in providing secure, authenticated communication for these networks. Traditional key management solutions reported in the literature lack both the flexibility and robustness required to cope with the dynamic nature of ad hoc networks. In this paper, we...
