Requirements and Challenges in Wireless Sensor Network Security

Abstract

The need of a powerful security mechanism has become essential, with the rapid growth of wireless sensor network. Since these networks may deal with confidential information or work in unfriendly unattended situations, it becomes extremely important that such security issues be strongly dealt withright from the system design phase. It is true that wireless sensor networks face issues which are totally different from that of customary networks because of restricted resources. Due to great potential of research, sensor networks have become hot topic for researchers. Keeping all these things in mind, we are trying to review the significant aspectsofsecurity of sensor network, and figure out the hindrances and prerequisites in wireless sensor security.
