In the recent times the concept of group key management is found to be one of the very essential issues in the field of wireless sensor network. Because of the dual impact limitations and various operations in open and hash environment the security and confidentiality which are considered as very challenging issues in WSN. The main issues which are associated with securing the sensor network have more complexity when the group communication of the network is considered. This paper addresses the security issues associated with the group key management techniques and ensures some significant conclusions for group key management in cluster tree WSNs.
