In this paper, a secure data communication environment for the three-tiered Wireless Sensor Networks (WSNs) that continues to operate correctly in a hostile medium is proposed. Considering the energy and hardware constraints of the sensor nodes, the low complex data confidential and authentication algorithms are proposed. Performance analysis of our protocol shows that it satisfies the energy and hardware limitations of the WSNs and maintains the secure fabrics of the network.
