Secure schemes in Wireless Sensor Network: A Survey

Abstract

-Wireless Sensor Network (WSN) is the combination of small devices called as sensor nodes which have sensing, computing and processing capabilities. Due to distributed nature of the WSNs, nodes are more vulnerable and can be physically accessible by an attacker; he/she can destroy the network and injects some extra bits in the information. An attacker can put some potential threats in the network. So, security is main concern in wireless sensor network especially in hostile environment. In this paper we focus on security requirements, threats and some security schemes that provide the solutions for such attacks.
