Wireless Sensor Networks (WSN) are network of sensors having low computation, storage and battery power. Hierarchical WSN are heterogeneous network of sensors having different capabilities which form a hierarchy to achieve energy efficiency. Key management algorithms are center of the security protocols in WSN. It involves key pre distribution, shared key discovery, key revocation, and refreshing. Due to resource constraints in WSN achieving a perfect key management scheme has been quite challenging. In this paper a new key management scheme for Hierarchical WSN based on Chinese Remainder Theorem has been proposed. An experimental setup is created to evaluate this scheme. The results indicate that it establishes the key with minimum computation, communication, storage cost at each node, also it is scalable and resilient to different attacks.
