Trust-ticket based authentication scheme for WSN multi-domain applications

With the increasing popularity of Wireless Sensor Networks (WSNs) in versatile domains demand crucial security concerns. Secure communication mechanisms in WSNs have been widely deployed to ensure confidentiality, authenticity and integrity of exchanging data. The authentication issue related to such networks has become a crucial service because the nodes are typically deployed in an unattended environment leaving them open to attack. Moreover, this is due to the resource-constrained nature of the sensor nodes, which are limited in computing power, data storage and communication capabilities. Any authentication protocol must be designed to operate efficiently in a resource constrained environment. In this paper, we propose an efficient trust-ticket based authentication protocol for multi-domain applications in WSNs. Through the security analysis, we demonstrate the robustness of our protocol against some well known attacks. Moreover, we perform an overall evaluation of our protocol through simulations in function of the network size, where we consider two scenarios according to the trusted authority number. The simulation results highlight the advantages of our protocol in terms of energy consumption.
