Keying technique in Wireless Sensor Networks(WSNs) is one of the most emerging fields of WSN security. In order to provide security on WSN, the role of Key distribution technique is considered to be very significant and thus the key management plays a crucial and fundamental roles in the security service of WSNs. This paper reviews pairwise key establishment technique along with the architecture and the environment of WSN. The cluster based group key agreement protocols for infrastructure base WSN are discussed in this paper. This paper also reviews how the security can be provided to WSNs with the integration of clustering and keying techniques. The survey also provides a more detailed discussion on the comparison between different cluster based group key agreement protocols.
