Hierarchical Approach for Key Management in Mobile Ad hoc Networks
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. The conventional security solutions to provide key management through accessing trusted authorities or centralized servers are infeasible for this new environment since mobile ad hoc networks...
متن کاملKey Management in Mobile Ad Hoc Networks
Mobile ad hoc networks (MANETs) eliminate the need for pre-existing infrastructure by relying on the nodes to perform all network services. The connectivity between the nodes is sporadic due to the shared, error-prone wireless medium and frequent route failures caused by node mobility. Fully self-organized MANETs are created solely by the end-users for a common purpose in an ad hoc fashion. For...
متن کاملSecurity Assessment for Key Management in Mobile Ad Hoc Networks
A mobile ad hoc network (MANET) is a kind of wireless communication system that doesn't have base stations or routers. The wireless connections can be a standard Wi-Fi connection or satellite, or another medium such as a cellular transmission. Specific applications like military or public emergency require secure group communication in ad hoc environments. Good Key management is very important ...
متن کاملSelf-Organized Public-Key Management for Mobile Ad Hoc Networks
In contrast with conventional networks, mobile ad hoc networks usually do not provide online access to trusted authorities or to centralized servers, and they exhibit frequent partitioning due to link and node failures and to node mobility. For these reasons, traditional security solutions that require online trusted authorities or certificate repositories are not well-suited for securing ad ho...
متن کاملA hierarchical key management scheme for secure group communications in mobile ad hoc networks
A mobile ad hoc network (MANET) is a kind of wireless communication infrastructure that does not have base stations or routers. Each node acts as a router and is responsible for dynamically discovering other nodes it can directly communicate with. However, when a message without encryption is sent out through a general tunnel, it may be maliciously attacked. In this paper, we propose a hierarch...
