Cryptography techniques are essential for a robust and stable security design of a system to mitigate the risk of external attacks and thus improve its efficiency. Wireless Sensor Networks (WSNs) play a pivotal role in sensing, monitoring, processing, and accumulating raw data to enhance the performance of the actuators, micro-controllers, embedded architectures, IoT devices, and computing machines to which they are connected. With so much threat of potential adversaries, it is essential to scale up the security level of WSN without affecting its primary goal of seamless data collection and communication with relay devices. This paper intends to explore the past and ongoing research activities in this domain. An extensive study of these algorithms referred here, are studied and analyzed. Based on these findings this paper will illustrate the best possible cryptography algorithms which will be most suited to implement the security aspects of the WSN and protect it from any threat and reduce its vulnerabilities. This study will pave the way for future research on this topic since it will provide a comprehensive and holistic view of the subject. |
