Performance Evaluation and Analysis of Encryption Schemes for Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) technology is one of the most important technologies of the Internet of things. It is effectively applied within several applications in the actual world, including health care, environmental monitoring, tracking, etc. WSNs consist of small sensor nodes having limited resources. The communication between the components of WSNs is unsecured though. Therefore, in order to secure the exchanged data, it is crucial to implement efficient and lightweight cryptographic schemes. In this paper, we evaluate the performance of different cryptosystems for WSNs. Our paper includes a comparison study between the studied encryption algorithms in terms of power consumption, required space memory, and computational time.
