Data aggregation scheme reduces the large amount of transmission in Wireless Sensor Networks (WSN). Concealed Data Aggregation schemes that are extended from homomorphic public encryption system are designed for a multi-application environment. The drawbacks of existing work include address aggregation security for Database As Service (DAS) Model. Client query aggregation increases the computation cost. Compromised secret keys affect the sensor node aggregations that are loosed. In DAS client stores database are on an entrusted service provider. The proposed work presented Concealed Data Aggregation for Database-AS-Service.
