EDPPS: An Energy-efficient Data Privacy Protection Scheme for wireless sensor networks

In wireless sensor networks (WSNs) sensors may be deployed in unpredictable environment, a limited energy of the sensor nodes has led to the development of the Energy-efficient Data Privacy Protection Scheme (EDPPS). 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 symmetric key cryptography algorithm for securing data. However, a current limitation of protecting data privacy in WSNs is that the symmetric key cryptography algorithms are vulnerable to node compromise attacks. To overcome this limitation, we investigate the facts of ensuring secure sensed data in a balanced energy network backbone based on distance from the source node to base station. Specifically, a checking data integrity mechanism has been proposed in this paper. Our analysis and simulation results show that EDPPS has a better performance through four abstract parameters: anonymity of the sensor nodes, confidentiality, authenticity and integrity of the actual sensed data. It also provides a good level for energy consumption as well as maximizing the network lifetime.
