摘要：We present an effective and secure mechanism for key distribution in wireless sensor network (WSN). Wireless sensor network finds unique and special applications as compare to the Wi Fi, Wi Max and etc networks because sensors are deployed in a very secret, hostile environment like battlefield, environmental monitoring, and health care industry. Various wireless sensor nodes are interconnected and form a wireless sensor network. Wireless sensor network are infrastructure less and can operating any environment as compare to the traditional network. WSN mainly consist of large number of tiny and simple nodes that are randomly deployed in operating areas unattended. Ma jor issue of WSN is to have a more secure network which is a function of Hash keys. More uses of Hash keys means enhance security but at the cost of power and area. In this paper, we introduce concept of Hash function to use a different key in each session between a pair of sensor, without allocating a large amount of memory space to store the keys. This scheme is based on multipath key reinforcement, this scheme is used to update the number of iteration to achieve a higher level of security. Increase usage of Hash keys means enhance security but at the cost of power and area. Paper also shown effect of number of Hash function of performance of wireless sensor node. This scheme is minimized the overhead introduce in the network
