Description: Reliable communication is mission critical to Emergency and Rescue operations.
MANET technology allowing communication where fixed infrastructure is not available
is very attractive for this setting. Emergency and Rescue operations may take place in
both hostile as well as benign environment. The communication system must handle
both situations. Security attacks can be launched towards any layer of the protocol
stack. What is new with wireless ad hoc networks is the network layer routing
information as a more probable target for security attacks. A reliable network service
cannot be provided without embracing routing information security. The primary
challenge is to decide which routing information can be trusted. The answer so far is
cryptographically signed routing messages. The possession of cryptographic keys serves
as proof of trustworthiness. A proper key management service is thus a critical factor
for the success of wireless ad hoc networks. Platform: |

Description: Wireless Embedded Systems (WEBs) has attracted significant interest in recent years, for instance, Wireless Sensor Networks (WSN), have recently been in the limelight for many domains. The characteristics of WEBs have imposed various restrictions on their system designs. Since embedded systems usually are developed by low-cost hardware, one major challenge in the development of many WEBs applications is to provide high-security features with limited resources. In this paper, we propose a novel key establishment scheme, named half-key scheme that based on the well-known random key pre-distribution scheme and DDHV-D deployment
knowledge to provide resource-efficient key management in WEBs with reduced memory space requirements and better security enforcement. The capability of the proposed approach is evaluated by an analytical model and a series of
experiments. Platform: |

Description: Wireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or
more sensor nodes and reveal all stored security information which enables him to compromise a part of the
WSN communications. Due to large number of sensor nodes and lack of information about deployment and
hardware capabilities of sensor node, key management in wireless sensor networks has become a complex task.
Limited memory resources and energy constraints are the other issues of key management in WSN. Hence an
efficient key management scheme is necessary which reduces the impact of node capture attacks and consume
less energy. In this study, we develop a cluster based technique for key management in wireless sensor network. Platform: |
