WSN Security: An Asymmetric Encryption and Hash Function based Approach

Abstract

Wireless Sensor Network (WSN) security is important for various futuristic applications like military, nuclear power plant, health care etc., In these applications the security is considered along with the additional challenging tasks such as low energy consumption, low computation capability and limited memory. In this paper a detailed investigation on the security related issues and challenges in WSN based on an asymmetric approach are made. Also an overview on various security frameworks based on asymmetric encryption and hash function is given.
