Trusted Third Party Authentication Protocol Development for Clustered Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) need effective security mechanisms because these networks are deployed in hostel unattended environments. There are many parameters which affect selecting the security mechanism as its speed and energy consumption. This paper presents a combined security system for WSN that enhance s the security of the network and it is energy consumption. This system combines three mechanisms, asymmetric, trusted third party, and pre-distribution. The performance evaluation demonstrates that the combined protocol can enlarge the life time for WSNs, and enhance its security. This integrated protocol can provide sufficient security no matter how many sensors are compromised . Fixed key storage overhead, full network connectivity, and low communication overhead can also be achieved. Consequently, it enhance s the immunity against different types of attacks. Moreover, this protocol is offered a high level of security for WSN considering its limited recourses. So it creates a balance between both security and constrained resources.
