Abstract

Wireless Sensor Networks (WSN) are comprised of many sensing devices that can exchange data for monitoring and tracking. Data is exchanged over different paths where a few of malicious nodes may exist to capture the data. To handle this issue, several data security schemes have been presented that are discussed in the literature. In this paper, we perform a Systematic Literature Review (SLR) to analyse existing schemes for data security in WSN as per the research question. It involves an inclusion and exclusion criteria for article selection. In literature, we explore the energy efficient schemes in the category of elliptic curve, AES, RSA, chaotic maps, efficient block ciphers, and various other techniques. These schemes are also evaluated in terms of key sizes, plain text sizes, and dominating features of related techniques and results. We identified that most of the data security schemes are extensive due to extensive computations and delayed responses. This work focuses various types of data security approaches that are compared to examine which can be more suitable for secure data exchange.
