The network made up by small nodes wirelessly is known as wireless sensor networks. This is one of the demanding technologies which are grown drastically. Now-a-day in most of the fields the authors use sensor technology. As per as the demands increase several other issues are also associated with it. These issues are security, fault tolerance, energy consumption, quality of service etc. Their main aim to write this paper is to give the more efficient approach to tackle with security issues. Due to increasing demands of sensors in military and other fields, it is very necessary to make them secure. Loss of useful and confidential information may lead the network to greater deficiency.
