Abstract: Wireless Sensor Network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions. WSN is a gateway that provides wireless connectivity back to the wired world or the distribution contract system includes. The nature of WSN as it is distributed and located in extreme conditions poses many security challenges to this type of networks. Ensuring security in WSN is challenging because most devices are resource constrained. In addition, different protocols that are used in these networks use their own set of security requirements. In this study, the security requirements of WSN are firstly identified. Then Public Key Infrastructure (PKI) is pointed out to be a feasible solution for distributing session keys, it has some difficulties to satisfy the requirements in availability, privacy preservation and scalability. PKI could be used in authenticating units and session keys. To complement the functions of PKI and overcome the rapidly changing conditions fuzzy rule based systems is used to provide a very convincing solution to decide the accurate session key length and other factors in WSN.
