In this paper, the authors investigate the facts of ensuring secure sensed data in a balanced energy network backbone, and propose Enhanced an Energy-Efficient Data Privacy Protection Scheme for wireless sensor networks (E-EDPPS). In Wireless Sensor Networks (WSNs), sensors may be deployed in an unpredictable environment where a limited energy of the sensor nodes has led to the development of EEDPPS. It is a process of ensuring privacy and security to the sensed data as well as maximizing the network lifetime. Many schemes have been proposed using a symmetric key cryptography algorithm for securing data in WSNs. However, a current limitation of these schemes is that the symmetric key cryptography algorithms are vulnerable to node compromise attacks.
