New Approach for Improving Security Measures of Private Key Algorithm in Wireless Sensor Network Environment

A wireless sensor network (WSN) is mainly made of distributed manually working sensors to monitor both physical and environmental conditions like temperature, sound, pressure, etc. and it collect the data from the all thee node and pass their data by the network to a main location. Nowadays many modern sensor networks are bi-directional, and it also control of sensor activity. Wireless sensor networks is mainly developed by the motivation of military applications like battlefield surveillance; today wireless sensor networks are mainly used in industrial and consumer applications like monitoring process of industry and health monitoring control industries and so on. So Many algorithms are already exits with many security limitations in wireless sensor network but with many limitation .For instance key maintenance is a great problem faced in less security level is a major problem of private key encryption methods even though key maintenance is hard .So by improving the security of this algorithm we can solve this problem.
