Key management is the one of the fundamental requirement for securing the Hierarchical Wireless Sensor Networks (HWSN) and also prevents adversarial activities. This paper presents a new pairwise key management scheme using matrix for HWSNs. In HWSN, cluster headers are more powerful than cluster members in all the resources like power, storage, communication and processing data. This heterogeneity alleviates the overhead of cluster members during the key establishment. All the expensive computations can be given to cluster headers in the network.
