Wireless Sensor Networks (WSNs) are constrained in terms of memory, computation, communication, and energy. To reduce communication overhead and energy expenditure in (WSNs), data aggregation is used. Data aggregation is a very important technique, but it gives extra opportunity to the adversary to attack the network, inject false messages into the network and trick the base station to accept false aggregation results. This paper presents a Secure Data Aggregation Framework (SDAF) for (WSNs). The goal of the framework is to ensure data integrity and data confidentiality.
