AB  - WSN is a way of handling dangerous and hostile environments safely. It replaces human existence
with nodes and units that could sustain its existence under extreme circumstances. The significance of WSN
arises from the importance of the data gathered through its nodes. Due to the fact of WSN that it is open air
environment, security issues must be considered for example authentication of new units and the encryption
of data transmitted between these units. This research provides a new model covering two important aspects
in WSN. The first aspect is the creation of the key that will be used for the current session between a pair of
nodes. In this step the research introduces the intuitionistic fuzzy sets to handle the WSN criteria
simultaneously and efficiently in order to decide the exact key length required depending on the status of the
network parameters. The second aspect is the distribution of the key between the units desiring
communications. This phase starts by authenticating each entity to each other and to the cluster head, then
one unit suggests a key and the other one confirms. It then starts communication using that key. This phase
shows the hybrid cryptography applied in which the algorithm uses asymmetric encryption for authentication
then uses symmetric encryption to secure the connection between the two units. Experimental results in this
research could categorized also into two classes. The first class is key size model in which the proposed model
compared to ordinary KNN and fuzzy model related to the determination of the key size. The proposed model
shows an overall efficient way relating to decide the key size. The second class of experiments is to distribute
the intermediate key efficiently at this point the proposed model shows resilience and efficiency compared to
distributing the key directly through cluster head.
