 Wireless Sensor Networks have been used practically every application because they give a cost-effective solution to real-world challenges. However, the sensor nodes have limited processing capacity, battery power, and memory. These nodes immediately transmit the measured environmental or physical data to the Base Station (BS). This direct transfer of data raises the cost of data connectivity. Furthermore, increased data exchange consumes more energy, reducing the lifespan of sensor networks. As a result, the data aggregation methodology is used in WSN to minimize transmission costs and extend the lifespan of sensor networks. Because the nodes are put in a hostile area and communicate through broadcast, the sensor nodes are quickly taken, and the aggregate data is quickly destroyed. As a result, data security is an important study topic in WSN. Because the sensor network has limited resources, specific wireless network security solutions cannot be used for WSN.The research that has been done indicates that lightweight block cyphers are the most effective method for protecting health data. The Provably Secured Data Aggregation (PSDA) method evaluates the outcomes of the AES, Simon, and Speck lightweight cryptosystems. The Speck method involves less time for calculation, which means it can be used for encryption and decryption. As a direct consequence of this, the Speck algorithm is utilised in order to encrypt patient information.
