In order to conserve wireless sensor network (WSN) lifetime, data aggregation is applied. Some researchers consider the importance of security and propose secure data aggregation protocols. The essential of those secure approaches is to make sure that the aggregators aggregate the data in appropriate and secure way. In this paper we give the description of ESPDA (Energy-efficient and Secure Pattern-based Data Aggregation) and SRDA (Secure Reference-Based Data Aggregation) protocol that work on cluster-based WSN and the deep security analysis that are different from the previously presented one.
