Key management in sensor networks is the core security protocols for wireless sensor networks (WSNs) in the hostile environment. Sensor nodes have highly constrained resource like limited battery power, memory, processing capabilities, etc. These limitations make infeasible to apply traditional key management techniques such as public key cryptography in the WSNs. For the existing key pre-distribution...
In this work, to obtain stronger connectivity, we propose and analyze a scheme extended by random key pre-distribution (RKP), which can work only in highly dense networks and require path construction. We investigate the threshold property of multi-hop key connectivity in random geometric networks. We have made use of the Jansonpsilas inequality to deal with the dependency overhead. Accordingly, our...
The communication of a wireless sensor network can be eaves dropped quite easily due to its properties, thereby requiring a security mechanism. Adding a key management scheme on the wireless sensor network is a kind of solution. This paper proposes a method to enhance the security of the existing random key pre-distribution scheme, that is considered to be suitable in wireless sensor networks. Using...
