In wireless sensor networks, data aggregation is a critical strategy for energy conservation. Compromised aggregators, on the other hand, might provide fake results and attempt to steal data from the system. several data-gathering strategies are using wireless sensor networks, each with its drawbacks. It is proposed SPAED (Secure Paillier key-based encrypted data aggregation). SPAED encrypts data using homomorphic encryption. Data is encrypted using the paillier key. Before authentication, the source data is decrypted. In comparison to other asymmetric systems, SPAED provides a high-level of security upon this aggregated result while consuming the least energy.
