Wireless sensor networks (WSNs) are ad-hoc networks composed of tiny devices with limited computation and energy capacities. For such devices, data transmission is a very energy-consuming operation. It thus becomes essential to the lifetime of a WSN to minimize the number of bits sent by each device. Concealed data aggregation (CDA) schemes that are based on the homomorphic characteristics of a privacy homomorphism (PH) enable end-to-end encryption in wireless sensor networks CDAMA is designed by using multiple points, each of which has different order. it is designed for a multi-application environment. it mitigates the impact of compromising attacks in single application environments and degrades the damage from unauthorized aggregations. In the database-service-provider model to maintain data privacy, clients need to outsource their data to servers in encrypted form. So that time, clients must still be able to execute queries over encrypted data.
